Description

MALODOR REDUCING COMPOSITION CONTAINING AMBER AND MUSK MATERIALS

TECHNICAL FIELD The present invention relates to malodor reducing compositions including an amber chemical material and a musk material, and consumer products including the malodor reducing compositions. The malodor reducing composition is designed to reduce malodor impression on surfaces, such as fabrics, hair, floors, etc., which, for example, have been contaminated with environmental odors such as cigarette smoke odors, cooking smoke odors, and/or that have been wetted with perspiration. The compositions are also useful for reducing malodor in confined air spaces such as bathrooms and kitchens and in reducing malodor in consumer products which contain inherently malodorous ingredients.

BACKGROUND OF THE INVENTION A wide variety of deodorizing compositions are known in the art, the most common of which only contain a perfume to mask the malodor. Odor masking is the intentional concealment of one odor by the addition of another. The preference to the masking perfume is varied greatly, depending on the application, e.g., underarm odor masking, fabric odor masking, bathroom odor masking, etc. Appropriate perfume ingredients need to be selected to connote freshness. Such odor masking composition known to those skilled in the art generally includes strong perfume ingredients and/or includes high volume of perfume composition, in order to achieve odor masking effect that meets consumer needs. However, some consumers do not prefer strong perfumes and/or long lasting perfumes remaining on the surface after treating such odor masking perfume, i.e., such consumers seek an odor masking product that have no odor or very faint odor after applying the product .

Odor modification, in which the odor is changed, e.g., by chemical modification, has also been used. Current malodor modification methods known in the art which do not simply mask odors are oxidative degradation, which uses oxidizing agents such as oxygen bleaches, chlorine, chlorinated materials such as sodium hypochlorite, chlorine dioxide, etc., and potassium permanganate to reduce malodor, and reductive degradation which uses reducing agents such as sodium bisulfite to reduce malodor. Both of these methods are unacceptable for use on fabrics because they can damage colored fabrics, specifically, they can bleach and discolor colored fabrics.

Other methods of odor control contain actives that are targeted to react with malodors having specific chemical functional groups. Examples of such actives are: biguanide polymers, which complex with organic compounds containing organically bound N and/or S atoms and fatty alcohol esters of methyl methacrylic acid which react with thiols, amines, and aldehydes. A more detailed description of these methods can be found in U.S. Pat. Nos. 2,544,093, 3,074,891 , and U.K. Pat. App. No. 941 ,105, all of said patents and applications are incorporated herein by reference. Other types of deodorizing compositions known in the art contain antibacterial and antifungal agents which regulate the malodor-producing microorganisms found on the surface to which the deodorizing composition is directed. Many skin deodorant products use this technology. These compositions are not effective on malodors that do not come from bacterial sources, such as cigarette smoke or cooking smoke odors.

Fabric malodor is most commonly caused by environmental odors such as cigarette smoke odor, cooking and/or cooking smoke odors, or body odor. The unpleasant odors are mainly organic molecules which have different structures and functional groups. One type of malodor that is very noticeable, and is commonly found on worn fabrics is low molecular weight, straight-chain, branched , and unsaturated Cρ-C-n fatty acids that cause axillary odor.

The condensation products of primary and secondary aliphatic alcohols with from about 1 to about 25 moles of ethylene oxide are suitable for use as the nonionic surfactant of the nonionic surfactant systems of the present invention. The alkyl chain of the aliphatic alcohol can either be straight or branched, primary or secondary, and generally contains from about 8 to about 22 carbon atoms. Preferred are the condensation products of alcohols having an alkyl group containing from about 8 to about 20 carbon atoms, more preferably from about 10 to about 18 carbon atoms, with from about 2 to about 10 moles of ethylene oxide per mole of alcohol. About 2 to about 7 moles of ethylene oxide and most preferably from 2 to 5 moles of ethylene oxide per mole of alcohol are present in said condensation products. Examples of commercially available nonionic surfactants of this type include TergitofT 15-S-9 (the condensation product of C-| i-C-|5 linear alcohol with 9 moles ethylene oxide), Tergitol^Tlvl 24-L-6 NMW (the condensation product of C-12-C14 primary alcohol with 6 moles ethylene oxide with a narrow molecular weight distribution), both marketed by Union Carbide Corporation; Neodol^{Tl l} 45-9 (the condensation product of C-14-C15 linear alcohol with 9 moles of ethylene oxide), NeodofT 23-3 (the condensation product of C-|2- "|3 linear alcohol with 3.0 moles of ethylene oxide), NeodolT 45-7 (the condensation product of C14-C-15 linear alcohol with 7 moles of ethylene oxide), Neodol^M 45.5 (the condensation product of C-14-C15 linear alcohol with 5 moles of ethylene oxide) marketed by Shell Chemical Company, KyroTM EOB (the condensation product of C13-C-15 alcohol with 9 moles ethylene oxide), marketed by The Procter & Gamble Company, and Genapol LA O3O or 05O (the condensation product of C12-C14 alcohol with 3 or 5 moles of ethylene oxide) marketed by Hoechst.

Any reducing saccharide containing 5 or 6 carbon atoms can be used, e.g., glucose, galactose and galactosyl moieties can be substituted for the glucosyl moieties (optionally the hydrophobic group is attached at the 2-, 3-, 4-, etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside). The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and/or 6- positions on the preceding saccharide units.

The preferred alkylpolyglycosides have the formula:

R²0(C_nH_2nO)t(glycosyl)_x

The glycosyl is preferably derived from glucose. To prepare these compounds, the alcohol or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1 -position). The additional glycosyl units can then be attached between their 1 -position and the preceding glycosyl units 2-, 3-, 4- and/or 6- position, preferably predominately the 2-position.

The condensation products of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol are also suitable for use as the additional nonionic surfactant systems of the present invention. The hydrophobic portion of these compounds will preferably have a molecular weight of from about 1500 to about 1800 and will exhibit water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially-available Plurafac™ LF404 and Pluronic™ surfactants, marketed by BASF. Also suitable for use as the nonionic surfactant of the nonionic surfactant system of the present invention, are the condensation products of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylenediamine. The hydrophobic moiety of these products consists of the reaction product of ethylenediamine and excess propylene oxide, and generally has a molecular weight of from about 2500 to about 3000. This hydrophobic moiety is condensed with ethylene oxide to the extent that the condensation product contains from about 40% to about 80% by weight of polyoxyethylene and has a molecular weight of from about 5,000 to about 11 ,000. Examples of this type of nonionic surfactant include certain of the commercially available TetronicT compounds, marketed by BASF.

Balance Comprising Carrier

The consumer products of the present invention may include balance comprising carrier. The level and species of the carrier are selected according to the compatibility with other components, and desired characteristic of the product. As used herein, the term "balance comprising carrier" includes any of the known balance comprising carriers, generally liquids, including water, C-1-C4 monohydric alcohols; C2-Cg polyhydric alcohols; propylene carbonate; liquid polyalkylene glycols; triethyl citrate; isopropyl myristate; benzyl benzoate; and the like; and mixtures thereof. The preferred carrier is aqueous solution, especially, water. The water which is used can be distilled, deionized, or tap water. Water not only serves as the liquid carrier. For example, in the case that consumer product of the present invention is a fabric freshening composition including cyclodextrin (which is fully described below), water not only serves as the liquid carrier of cyclodextrins, but it also facilitates the complexation reaction between the cyclodextrin molecules and any malodorous molecules that are on the fabric when it is treated. It has recently been discovered that water has an unexpected odor controlling effect of its own. It has been discovered that the intensity of the odor generated by some polar, low molecular weight organic amines, acids, and mercaptans is reduced when the odor-contaminated surfaces are treated with an aqueous solution. Not to be bound by theory, it is believed that water solubilizes and depresses the vapor pressure of these polar, low molecular weight organic molecules, thus reducing their odor intensity. In the case that consumer product is a hair treating composition, for example, a high percentage of volatile solvents of low boiling point and/or propellant are suitably used for product forms aimed to be left on the hair. Volatile solvents useful herein include water, lower alkyl alcohols having from 1 to 3 carbons, and hydrocarbons having from about 5 to about 8 carbons, The preferred volatile solvents are water, ethanol, isopropanol, pentane, hexane, and heptane. The water useful herein include deionized water and water from natural sources containing mineral cations. Deionized water is preferred. In the case that consumer product is an air freshening composition, one or more, volatile solvents are generally included in the composition.

Non-volatile solvents useful herein include alkyl alcohols having more than 3 carbons, and polyhydric alcohols. The polyhydhc alcohols useful herein include 1 ,2-proprane diol or propylene glycol, 1 ,3-propane diol, hexylene glycol, glycerin, diethylene glycol, dipropylene glycol, 1 ,2-butylene glycol, and 1 ,4- butylene glycol.

Propellants may be used for consumer products e.g., mousse and hair spray product forms. Propellants, when used in the present invention, are selected depending on variables such as the remainder of components, the package, and whether the product is designed to be used standing or invert.

Propellants useful herein include fluorohydrocarbons such as difluoroethane 152a available from DuPont, dimethylether, and hydrocarbons such as propane, isobutane, n-butane, mixture of hydrocarbons such as LPG (liquid petroleum gas), carbon dioxide, nitrous oxide, nitrogen, and compressed air.

The carriers are generally present at from about 0.5% to about 99.5%, preferably from about 5.0% to about 99.5%, more preferably from about 10.0% to about 98.0%, of the consumer products of the present invention.

Specific Consumer Products The following specific consumer products further describe the preferred examples within the scope of present invention.

(i) Fabric Freshening Compositions The fabric freshening composition of the present invention preferably includes: from about 0.002% to about 1% of a malodor reducing composition of the present invention; from about 0.01% to about 5% of a cyclodextrin; and the balance comprising carrier, wherein the total amount of the amber chemical material and the musk material (1) in the malodor reducing composition is at least about 5% by weight; and (2) in the fabric freshening composition is from about 0.0001% to about 1%. I. Cyclodextrin

The fabric freshening composition generally include cyclodextrin. As used herein, the term "cyclodextrin" includes any of the known cyclodextrins such as unsubstituted cyclodextrins containing from six to twelve glucose units, especially, alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and/or their derivatives and/or mixtures thereof. The alpha-cyclodextrin consists of six glucose units, the beta-cyclodextrin consists of seven glucose units, and the gamma-cyclodextrin consists of eight glucose units arranged in donut-shaped rings..

Preferably, the cyclodextrins used in the present invention are highly water-soluble such as, alpha-cyclodextrin and/or derivatives thereof, gamma- cyclodextrin and/or derivatives thereof, derivatised beta-cyclodextrins, and/or mixtures thereof. The derivatives of cyclodextrin consist mainly of molecules wherein some of the OH groups are converted to OR groups. Cyclodextrin derivatives include, e.g., those with short chain alkyl groups such as methylated cyclodextrins, and ethylated cyclodextrins, wherein R is a methyl or an ethyl group; those with hydroxyalkyl substituted groups, such as hydroxypropyl cyclodextrins and/or hydroxyethyl cyclodextrins, wherein R is a -CH2-CH(OH)- CH3 or a "CH2CH2-OH group; branched cyclodextrins such as maltose-bonded cyclodextrins; cationic cyclodextrins such as those containing 2-hydroxy-3- (dimethylamino)propyl ether, wherein R is CH2-CH(OH)-CH2-N(CH3)2 which is cationic at low pH; quaternary ammonium, e.g., 2-hydroxy-3- (trimethylammonio)propyl ether chloride groups, wherein R is CH2-CH(OH)-CH2- N⁺(CH3)3CI^_; anionic cyclodextrins such as carboxymethyl cyclodextrins, cyclodextrin sulfates, and cyclodextrin succinylates; amphoteric cyclodextrins such as carboxymethyl/quaternary ammonium cyclodextrins; cyclodextrins wherein at least one glucopyranose unit has a 3-6-anhydro-cyclomalto structure, e.g., the mono-3-6-anhydrocyclodextrins, as disclosed in "Optimal Performances with Minimal Chemical Modification of Cyclodextrins", F. Diedaini-Pilard and B. Perly, The 7th International Cyclodextrin Symposium Abstracts, April 1994, p. 49, said references being incorporated herein by reference; and mixtures thereof. Other cyclodextrin derivatives are disclosed in U.S. Pat. Nos: 3,426,011 , Parmerter et al., issued Feb. 4, 1969; 3,453,257; 3,453,258; 3,453,259; and 3,453,260, all in the names of Parmerter et al., and all issued July 1 , 1969; 3,459,731 , Gramera et al., issued Aug. 5, 1969; 3,553,191 , Parmerter et al., issued Jan. 5, 1971 ; 3,565,887, Parmerter et al., issued Feb. 23, 1971 ; 4,535,152, Szejtli et al., issued Aug. 13, 1985; 4,616,008, Hirai et al., issued Oct. 7, 1986; 4,678,598, Ogino et al., issued Jul. 7, 1987; 4,638,058, Brandt et al., issued Jan. 20, 1987; and 4,746,734, Tsuchiyama et al., issued May 24, 1988; all of said patents being incorporated herein by reference. Highly water-soluble cyclodextrins are those having water solubility of at least about 10 g in 100 ml of water at room temperature, preferably at least about 20 g in 100 ml of water, more preferably at least about 25 g in 100 ml of water at room temperature. The availability of solubilized, uncomplexed cyclodextrins provides for effective and efficient odor control performance. Solubilized, water- soluble cyclodextrin can exhibit more efficient odor control performance than non-water-soluble cyclodextrin when deposited onto surfaces, especially fabric.

Examples of preferred water-soluble cyclodextrin derivatives suitable for use herein are hydroxypropyl alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkyl cyclodextrin derivatives preferably have a degree of substitution of from about 1 to about 14, more preferably from about 1.5 to about 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of from about 1 to about 18, preferably from about 3 to about 16. A known methylated beta-cyclodextrin is heptakis-2,6-di-O-methyl-β- cyclodextrin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14. A preferred, more commercially available, methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having different degrees of substitution, normally of about 12.6. RAMEB is more preferred than DIMEB, since DIMEB affects the surface activity of the preferred surfactants more than RAMEB. The preferred cyclodextrins are available, e.g., from Cerestar USA, Inc. and Wacker Chemicals (USA), Inc.

It is also preferable to use a mixture of cyclodextrins. Such mixtures absorb odors more broadly by complexing with a wider range of odoriferous molecules having a wider range of molecular sizes. Preferably at least a portion of the cyclodextrins is alpha-cyclodextrin and its derivatives thereof, gamma- cyclodextrin and its derivatives thereof, and/or derivatised beta-cyclodextrin, more preferably a mixture of alpha-cyclodextrin, or an alpha-cyclodextrin derivative, and derivatised beta-cyclodextrin, even more preferably a mixture of derivatised alpha-cyclodextrin and derivatised beta-cyclodextrin, most preferably a mixture of hydroxypropyl alpha-cyclodextrin and hydroxypropyl beta- cyclodextrin, and/or a mixture of methylated alpha-cyclodextrin and methylated beta-cyclodextrin. For controlling odor on fabrics, the composition is preferably used as a spray. It is preferable that usage of fabric freshening comositions of the present invention contain low levels of cyclodextrin so that a visible stain does not appear on the fabric at normal usage levels. Preferably, the solution used to treat the surface under usage conditions is virtually not discernible when dry. Typical levels of cyclodextrin in usage compositions for usage conditions are from about 0.01% to about 5%, preferably from about 0.1% to about 4%, more preferably from about 0.5% to about 2% by weight of the composition. Compositions with higher concentrations can leave unacceptable visible stains on fabrics as the solution evaporates off of the fabric. This is especially a problem on thin, colored, synthetic fabrics. In order to avoid or minimize the occurrence of fabric staining, it is preferable that the fabric be treated at a level of less than about 5 mg of cyclodextrin per gram of fabric, more preferably less than about 2 mg of cyclodextrin per gram of fabric. The presence of the surfactant can improve appearance by minimizing localized spotting. Concentrated compositions can also be used in order to deliver a less expensive product. When a concentrated product is used, i.e., when the level of cyclodextrin used is from about 3% to about 20%, more preferably from about 5% to about 10%, by weight of the concentrated composition, it is preferable to dilute the concentrated composition before treating fabrics in order to avoid staining. Preferably the concentrated cyclodextrin composition is diluted with about 50% to about 6000%, more preferably with about 75% to about 2000%, most preferably with about 100% to about 1000% by weight of the concentrated composition of water. The resulting diluted compositions have usage concentrations of cyclodextrin as discussed hereinbefore, e.g., of from about 0.1 % to about 5%, by weight of the diluted composition.

II. Optional Ingredients for Fabric Freshening Compositions

Optionally, fabric freshening compositions of the present invetnion may include: (a) cyclodextrin-compatible surfactant (e.g., block copolymers of ethylene oxide and propylene oxide, preferable non-limiting examples includes polyalkyleneoxide polysiloxanes having a dimethyl polysiloxane hydrophobic moiety and one or more hydrophilic polyalkylene side chains) ; (b) cyclodextrin compatible antimicrobial active (e.g., biguanides and quaternary compounds); (c) low molecular weight polyols (e.g., ethylene glycol, propylene glycol and/or glycerol); (d) optional aminocarboxylate chelators (e.g., ethylenediaminetetraacetic acid (EDTA), hydroxyethylene-diaminet acetic acid, diethylenetriaminepentaacetic acid, and other aminocarboxylate chelators, and mixtures thereof, and their salts, and mixtures thereof); (e) metal salts (e.g., copper salts, zink salts, and mixtures thereof); (f) humectant (e.g., glycerine, inorganic hygroscopic material); (g) adjunct odor-controlling materials; (h) chelating agents; (i) antistatic agents; 0) insect and moth repelling agents; (k) colorants; (I) antioxidants, and mixtures thereof .

The compositions of the present invention can optionally include one or more other hard surface cleaning adjunct materials, carriers, solvents or other materials for assisting or enhancing cleaning performance, treatment of the substrate to be cleaned, or to modify the aesthetics of the detergent composition (e.g., perfumes, colorants, dyes, etc.). Builders

Builders can optionally be included in the compositions herein to assist in controlling mineral hardness. Preferable are builders that have reduced filming/streaking characteristics at the critical levels of the compositions of the present invention. Addition of specific surfactant builders at critical levels further improves cleaning without the problem of filming/streaking that usually occurs when surfactant builders are added to hard surface cleaners. In light of the improvement displayed by the compositions of the present invention, however, the need for builders to prevent filming and streaking is reduced. Inorganic as well as organic builders can be used.

The level of builder can vary widely depending upon the end use of the composition and its desired physical form. When present, the compositions will typically comprise at least about 0.1% builder. Liquid formulations typically comprise from about 0.1% to about 5%, more typically about 0.2% to about 2%, by weight, of surfactant builder. Lower or higher levels of builder, however, are not meant to be excluded.

Builders suitable for use in the compositions of the present invention include polycarboxylates and phosphates as well as others cited hereinafter. Included among the polycarboxylate builders are a variety of categories of useful materials. One important category of polycarboxylate builders encompasses the ether polycarboxylates, including oxydisuccinate, as disclosed in Berg, U.S. Patent 3,128,287, issued April 7, 1964, and Lamberti et al, U.S. Patent 3,635,830, issued January 18, 1972. See also "TMS/TDS" builders of U.S. Patent 4,663,071 , issued to Bush et al, on May 5, 1987. Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Patents 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903.

Other useful builders include the ether hydroxypolycarboxylat.es, copoly- mers of maleic anhydride with ethylene or vinyl methyl ether, 1 , 3, 5-trihydroxy benzene-2, 4, 6-trisulphonic acid, and carboxymethyloxysuccinic acid, the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethylene-diamine tetraacetic acid and nit lotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene 1 ,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof.

Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance due to their availability from renewable resources and their biodegradability. Oxydisuccinates are also especially useful in the compositions and combinations of the present invention.

A preferred polycarboxylate builder is iminodisuccinate. Other suitable polycarboxylates are disclosed in U.S. Patent 4,144,226, Crutchfield et al, issued March 13, 1979 and in U.S. Patent 3,308,067, Diehl, issued March 7, 1967. See also Diehl U.S. Patent 3,723,322.

Suitable additional optional detergent builders include salts of ethylenediaminetetraacetic acid (hereinafter EDTA), citric acid, nitroacetic acid, (hereinafter NTA), sodium carboxymethylsuccinic acid, sodium N-(2-hydroxy- propyl)-iminodiacetic acid, and N-diethyleneglycol-N,N-diacetic acid (hereinafter DIDA). The salts are preferably compatible and include ammonium, sodium, potassium and/or alkanolammonium salts. The alkanolammonium salt is preferred as described hereinafter. A preferred detergent builder are the mixtures citric acid/acetate and bicarbonate/carbonate, more preferred bicarbonate/carbonate. The additional optional surfactant builders, when present, are typically at levels of from about 0.01 % to about 0.5%, more preferably from about 0.02% to about 0.3%, most preferably form about 0.02% to about 0.15%. The levels of these additional builders, present in the wash solution of hard surfaces that comprise glass should be less than about 0.2%. Chelating Agents The hard surface cleaning compositions herein may also optionally contain one or more transition metal chelating agents. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates.

Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilo- triacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein.

A preferred biodegradable chelator for use herein is ethylenediamine disuccinate ("EDDS"), especially the [S,S] isomer as described in U.S. Patent 4,704,233, November 3, 1987, to Hartman and Perkins.

If utilized, these chelating agents will generally comprise from about 0.1% to about 10% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.1% to about 3.0% by weight of such compositions. Optional Solvents

Optionally, the compositions of the present invention further comprise one or more solvents. Solvents are broadly defined as compounds that are liquid at temperatures of 20°C-25°C and which are not considered to be surfactants. One of the distinguishing features is that solvents tend to exist as discrete entities rather than as broad mixtures of compounds. Solvents of this invention contain from about 1 carbon atom to about 35 carbon atoms, and contain contiguous linear, branched or cyclic hydrocarbon moieties of no more than about 8 carbon atoms. Examples of suitable solvents for the present invention include, methanol, ethanol, propanol, isopropanol, 2-methyl pyrrolidinone, benzyl alcohol and morpholine n-oxide. Preferred among these solvents are methanol and isopropanol.

In a preferred embodiment of the invention, the solvents are selected from the group of compounds comprising ether derivatives of mono-, di- and tri- ethylene glycol, propylene glycol, butylene glycol ethers, and mixtures thereof. The molecular weights of the preferred solvents are less than about 350, more preferably between about 100 and about 300, even more preferably between about 115 and about 250. Examples of preferred solvents include, for example, mono-ethylene glycol n-hexyl ether, mono-propylene glycol n-butyl ether, and tri- propylene glycol methyl ether. Ethylene glycol and propylene glycol ethers are commercially available from the Dow Chemical Company under the tradename "Dowanol" and from the Arco Chemical Company under the tradename "Arcosolv". Other preferred solvents including mono- and di-ethylene glycol n- hexyl ether are available from the Union Carbide company. Preferred solvents according to this invention are present in from about 1% to about 10%, more preferably from about 2% to about 8%, most preferably from about 3% to about 7%, by weight of the hard surface cleaner composition.

Basic Blue 80), Drima ne Blue Z-RL (Cl. Reactive Blue 18), Alizarine Light Blue H-RL (Cl. Acid Blue 182), FD&C Blue No. 1 and FD&C Green No. 3. (See the patents of Kitko, U.S. Pat. No. 4,248,827 issued February 3, 1981 and U. S. Pat. No. 4,200,606, issued April 29, 1980, both incorporated herein by reference.) Cl. refers to Color Index. Polymeric Dispersing Agents

Polymeric dispersing agents can advantageously be utilized at levels from about 0.1% to about 7%, by weight, in the compositions herein. Suitable polymeric dispersing agents include polymeric polycarboxylates, polystyrene sulfonates and polyethylene glycols, although others known in the art can also be used. It is believed, though it is not intended to be limited by theory, that polymeric dispersing agents enhance overall detergent builder performance, when used in combination with other builders (including lower molecular weight polycarboxylates) by crystal growth inhibition, particulate soil release peptization, and anti-redeposition.

Polymeric polycarboxylate materials can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein or monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight.

Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water-soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most preferably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials. Use of polyacrylates of this type in detergent compositions has been disclosed, for example, in Diehl, U.S. Patent 3,308,067, issued March 7, 1967.

Acrylic/maleic-based copolymers may also be used as a preferred component of the dispersing/anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form preferably ranges from about 2,000 to 100,000, more preferably from about 5,000 to 75,000, most preferably from about 7,000 to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1 :1 , more preferably from about 10:1 to 2:1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent Application No. 66915, published December 15, 1982, as well as in EP 193,360, published September 3, 1986, which also describes such polymers comprising hydroxyp ropy lacry late. Still other useful dispersing agents include the maleic/acrylic/vinyl alcohol terpolymers. Such materials are also disclosed in EP 193,360, including, for example, the 45/45/10 terpolymer of acrylic/maleic/vinyl alcohol.

Another polymeric material which can be included is polyethylene glycol (PEG). PEG can exhibit dispersing agent performance as well as act as a clay soil removal-antiredeposition agent. Typical molecular weight ranges for these purposes range from about 500 to about 100,000, preferably from about 1 ,000 to about 50,000, more preferably from about 1 ,500 to about 10,000.

Polyaspartate and polyglutamate dispersing agents may also be used. Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) of about 10,000. Abrasives

An essential component of many solid or viscous semi-solid hard surface cleaning compositions is the abrasive material added to facilitate the action of scouring. Abrasive scouring cleansers provide a convenient and useful means for carrying out the sanitizing of porcelain and tile surfaces, especially tubs, showers and toilet bowls. The particulate abrasive material within such compositions serves to abrade and loosen soil adhering to hard surfaces and further serves to create more intimate contact between hard surface stain and the surfactant and/or bleaching agents also present in the cleansing compositions.

Abrasive cleaners have traditionally contained water-insoluble, relatively hard, particulate mineral material as the abrasive agent. The most common such abrasive agent is finely divided silica sand having particle size varying between about 1 and 300 microns and specific gravity of about 2.1 or higher. While such material is generally very effective in scouring soil and stains from the surfaces being treated, abrasive material of this type tends to be difficult to rinse away from the toilet bowl, shower or bathtub surface.

It has been discovered that abrasive compositions of this desired type can be realized by utilizing a particular type of expanded perlite abrasive in combination with the surfactants, filler material, and other optional scouring material ingredients listed herein. The abrasive materials suitable to the present invention are those contained in U.S. Pat. No. 4,051 ,056, Hartman, issued September 27, 1977 and included herein by reference.

I. Optional Ingredients for Antiperspirant and/or Deodorant Compositions

Some antiperspirant gel stick compositions of the present invention may include the ingredients discussed below. Although the term "stick" as utilized herein includes semi-solid forms (i.e., preferably having a viscosity of at least about 1 ,000,000 centipoise at 25°C), solid forms (i.e., preferably having an average penetration value within a given production batch from about 3 to about 25 mm over a period of 5 seconds as measured utilizing American Society for Testing Materials (ASTM) Method D-5, with a penetration cone (Model H1312; sold by Humbolt Manufacturing Company) weighing 2.0 g (making the total mass 50 g and a Sommer & Runge Model PNR10 Penetrometer) are preferred. Gelling Agent:

The "gelling agent" as used herein is a mixture of a primary gellant and a secondary gellant; both discussed hereinafter. The primary gellant is selected from the group consisting of 12-hydroxystearic acid, esters of 12-hydroxystearic acid, amides of 12-hydroxystearic acid and mixtures thereof. The secondary gellant is selected from the group consisting of n-acyl amino acid derivatives. The level of the gelling agent within the composition is typically from about 1% to about 15%; preferably, from about 3% to about 12%; more preferably, from about 5% to about 10%. The primary gellan secondary gellant ratio is typically between about 1 :2 and about 20:1 ; preferably, from about 1 :1 to about 10:1 ; more preferably, from about 2:1 to about 7:1 ; and even more preferably, from about 3:1 to about 5:1. The primary gellan secondary gellant ratio appears to be more critical when the level of polar, non-volatile liquid within the liquid base material (discussed hereinafter) in the composition is relatively low; e.g., below about 25%.

This gelling agent offers significant benefits when used in an antiperspirant gel stick. The gelling agent of the present invention exhibits unexpected benefits, e.g., decreased residue upon application to the skin, increased hardness and better aesthetics, relative to a similar composition having either of the two gellants alone. In fact, these gellants in combination are more effective than either alone so that the overall level of gelling agent within the composition can be reduced while maintaining such desirable stick characteristics. Moreover, when these gellants are used together as the gelling agent of the present invention, degradation of the gelling agent by the acidic antiperspirant active during manufacturing is unexpectedly significantly reduced; i.e., as compared to each gellant alone. To further reduce degredation, a heated solution of the gelling agent and the liquid base material preferably remains in solution such that the antiperspirant active can be substantially uniformely mixed therein at a temperature less than about 120°C; more preferably, less than about 105°C; more preferably, less than about 95°C; and most preferably, less than about 80°C (hereinafter, the "mixing temperature"). This reduced mixing temperature is made possible partly because the primary gellant, once molten, is an unexpectedly good co-solvent for the secondary gellant, thereby facilitating their dissolution at a lower temperature. Additional methods of reducing the mixing temperature or otherwise enabling a reduction of the interaction of the acidic antiperspirant active with other components, e.g., the gelling agent, is discussed hereinafter. Since lower mixing temperatures can be utilized, the gelling agent is more compatible with additional gel stick components which have lower boiling points, such as perfumes, a. Primary Gellant

The primary gellant of the gelling agent of the present invention is selected from the group consisting of 12-hydroxystearic acid, esters of 12-hydroxystearic acid, amides of 12-hydroxystearic acid and mixtures thereof. The primary gellant is preferably selected from the group consisting of 12-hydroxystearic acid, 12- hydroxystearic acid methyl ester, 12-hydroxystearic acid ethyl ester, 12- hydroxystearic acid stearyl ester, 12-hydroxystearic acid benzyl ester, 12- hydroxystearic acid amide, isopropyl amide of 12-hydroxystearic acid, butyl amide of 12-hydroxystearic acid, benzyl amide of 12-hydroxystearic acid, phenyl amide of 12-hydroxystearic acid, t-butyl amide of 12-hydroxystearic acid, cyclohexyl amide of 12-hydroxystearic acid, 1-adamantyl amide of 12-hydroxystearic acid, 2- adamantyl amide of 12-hydroxystearic acid, diisopropyl amide of 12- hydroxystearic acid, and mixtures thereof; even more preferably, 12- hydroxystearic acid, isopropyl amide of 12-hydroxystearic acid, and mixtures thereof. b. Secondary Gellant

With regard to the secondary gellant of the gelling agent of the present invention, N-acyl amino acid derivatives include N-acyl amino acid amides and N- acyl amino acid esters prepared from glutamic acid, lysine, glutamine, aspartic acid and mixtures thereof.

Preferably the N-acyl amino acid derivatives are selected from the group consisting of N-lauroyl-glutamic acid diethyl amide, N-lauroyl-glutamic acid dibutyl amide, N-lauroyl-glutamic acid dihexyl amide, N-lauroyl-glutamic acid dioctyl amide, N-lauroyl-glutamic acid didecyl amide, N-lauroyl-glutamic acid didodecyl amide, N-lauroyl-glutamic acid ditetradecyl amide, N-lauroyl-glutamic acid dihexadecyl amide, N-lauroyl-glutamic acid distearyl amide, N-stearoyl-glutamic acid dibutyl amide, N-stearoyl-glutamic acid dihexyl amide, N-stearoyl-glutamic acid diheptyl amide, N-stearoyl-glutamic acid dioctyl amide, N-stearoyl-glutamic acid didecyl amide, N-stearoyl-glutamic acid didodecyl amide, N-stearoyl-glutamic acid ditetradecyl amide, N-stearoyl-glutamic acid dihexadecyl amide, N-stearoyl- glutamic acid distearyl amide and mixtures thereof; more preferred, is n-lauroyl- glutamic acid dibutyl amide, n-stearyl-glutamic acid dihexyl amide, and mixtures thereof. Liquid Base Materials

The liquid base matrix of antiperspirant stick compositions of the present invention is formed by combining the gelling agent with a liquid base material. As used herein, the term "liquid" refers to materials which are liquids at ambient conditions and the term "liquid base material" includes all liquids within the composition. It is important that the liquid base material be of a type, and used at a level sufficient to solubilize the gelling agent when heated, to permit substantially uniform mixing of the antiperspirant active into the heated solution at the mixing temperature, and form a stick when cooled to ambient temperature. The liquid base material should be compatible with the gelling agent so that the mixture of the two remains homogeneous and does not phase separate during manufacturing and so that the finished product remains homogeneous and does not phase separate at ambient conditions over the normal shelf-life which may be upwards of one year. Furthermore, the liquid base materials are typically selected to provide aesthetic benefits, such as emolliency, low tack or minimized visible residue, without significant interference with the effectiveness of the antiperspirant active component. Lastly, the particular liquid base material should be safe for application to human skin.

The liquid base materials include emollients which have a solubility parameter from about 5 to about 11. It is preferable that, in aggregate, the average solubility parameter of the liquid base material be from about 6 to about

10. Hence, a mixture of emollients may be used as the liquid base material herein, each having a solubility parameter in the range of from about 5 to about

11 , such that the average solubility parameter of the mixture is from about 6 to about 10. Solubility parameters are common to the art of antiperspirant stick formulation and the means to determine them are disclosed by CD. Vaughan, "Solubility Effects in Product, Package, Penetration and Preservation" 103 Cosmetics and Toiletries 47-69, October, 1988; and CD. Vaughan, " Using Solubility Parameters in Cosmetics Formulation", 36 J Soc. Cosmetic Chemists 319-333, Sept/Oct, 1985. The liquid base material of the present invention is preferably used at levels from about 10% to about 95%; and more preferably from about 45% to about 80%. The liquid base material preferably includes a volatile, non-polar, oil and a non-volatile, relatively polar co-solvent; each discussed more fully hereinafter. The term "non-volatile" as used herein refers to materials which exhibit a vapor pressure of no more than about 0.2mm Hg at 25°C at one atmosphere and/or to materials which have a boiling point at one atmosphere of at least about 300°C The term "volatile" as used herein refers to all materials which are not "non-volatile" as previously defined herein. The phrase "relatively polar" as used herein means more polar than another material in terms of solubulity parameter; i.e., the higher the solubility parameter the more polar the liquid. The term "non-polar" typically means that the emollient has a solubility parameter below about 6.5. a. Non-polar, Volatile Oil

The non-polar, volatile oil tends to impart highly desirable aesthetic properties to the gel stick. Consequently, the non-polar, volatile oils are preferably utilized at a fairly high level. Such non-polar, volatile oils are preferably used at levels from about 10% to about 70%; more preferably, from about 25% to about 60%; more preferably from about 40% to about 60%.

Non-polar, volatile oils particularly useful in the present invention are selected from the group consisting of silicone oils; hydrocarbons; and mixtures thereof. Such non-polar, volatile oils are disclosed, for example, in Cosmetics, Science, and Technology, Vol. 1 , 27-104 edited by Balsam and Sagarin, 1972. The non-polar, volatile oils useful in the present invention may be either saturated or unsaturated, have an aliphatic character and be straight or branched chained or contain alicyclic or aromatic rings. Examples of preferred non-polar, volatile hydrocarbons include isodecane (such as Permethyl-99A® which is available from Presperse Inc.) and the C7-C8 through C12-C15 isoparaffins (such as the Isopar® Series available from Exxon Chemicals).

Non-polar, volatile silicone oils are highly preferred as the non-polar, volatile oil in the liquid base material, since they endow the antiperspirant stick composition with highly desirable aesthetics. Non-polar, volatile liquid silicone oils are disclosed in U.S. Pat. 4,781 ,917 issued to Luebbe et al. on Nov. 1 , 1988. Additionally, a description of various volatile silicones materials is found in Todd et al., "Volatile Silicone Fluids for Cosmetics", Cosmetics and Toiletries, 91 :27-32 (1976). Particularly preferred volatile silicone oils are cyclic and linear volatile silicones like those disclosed hereinbefore. b. Relatively Polar. Non-volatile Co-solvent

The relatively polar co-solvent aids in the utilization of reduced processing temperatures by solubulizing at least one of the gellants and being soluble in the non-polar, volatile oil when subjected to reduced processing temperatures. The non-volatile co-solvent is "relatively polar" as compared to the non-polar, volatile oil discussed above. Therefore, the non-volatile co-solvent is more polar (i.e., has a higher solubility parameter) than at least one of the non-polar, volatile oils.

In addition to enabling reduced processing temperatures, the co-solvent enables the inclusion of greater amounts of the non-polar, volatile oil. This is advantageous because, as discussed above, the non-polar, volatile oil provides significant cosmetic benefits. The quantity of relatively polar, non-volatile co- solvent, however, is preferably kept to a minimum because it tends to adversely affect product cosmetics. Thus, the relatively polar, non-volatile co-solvent is preferably included at levels from about 5% to about 60%; more preferably from about 5% to about 25%; and most preferably from about 7% to about 20%.

Relatively polar, non-volatile liquids potentially useful as the co-solvent in the present invention are disclosed, for example, in Cosmetics, Science, and Technology, Vol. 1 , 27-104 edited by Balsam and Sagarin, 1972; U.S. Pat. 4,202,879 issued to Shelton on May 13, 1980; and U.S. Pat. 4,816,261 issued to Luebbe et al. on March 28, 1989. Relatively polar, non-volatile co-solvents useful in the present invention are preferably selected from the group consisting of silicone oils; hydrocarbon oils; fatty alcohols; fatty acids; esters of mono and dibasic carboxylic acids with mono and polyhydric alcohols; polyoxyethylenes; polyoxypropylenes; mixtures of polyoxyethylene and polyoxypropylene ethers of fatty alcohols; and mixtures thereof. The relatively polar, non-volatile co-solvents useful in the present invention may be either saturated or unsaturated, have an aliphatic character and be straight or branched chained or contain alicyclic or aromatic rings. More preferably, the relatively polar, non-volatile liquid co-solvent are selected from the group consisting of fatty alcohols having from about 12-26 carbon atoms; fatty acids having from about 12-26 carbon atoms; esters of monobasic carboxylic acids and alcohols having from about 14-30 carbon atoms; esters of dibasic carboxylic acids and alcohols having from about 10-30 carbon atoms; esters of polyhydric alcohols and carboxylic acids having from about 5-26 carbon atoms; ethoxylated, propoxylated, and mixtures of ethoxylated and propoxylated ethers of fatty alcohols with from about 12-26 carbon atoms and a degree of ethoxylation and propoxylation of below about 50; and mixtures thereof.

More preferred are propoxylated ethers of C14-C18 fatty alcohols having a degree of propoxylation below about 50, esters of C₂-Cg alcohols and C₁₂-C₂₆ carboxylic acids (e.g. ethyl myristate, isopropyl palmitate), esters of C₁₂-C₂₆ alcohols and benzoic acid (e.g. Finsolv TN® supplied by Finetex), diesters of C₂- Cδ alcohols and adipic, sebacic, and phthalic acids (e.g., diisopropyl sebacate, diisopropyl adipate, di-n-butyl phthalate), polyhydric alcohol esters of Cg-C₂₆ carboxylic acids (e.g., propylene glycol dicaprate/dicaprylate, propylene glycol isostearate); and mixtures thereof.

Even more preferred are branched-chain aliphatic fatty alcohols having from about 12-26 carbon atoms. Even more preferred is isocetyl alcohol, octyldecanol, octyldodecanol and undecylpentadecanol; and most preferred is octyldodecanol. Such preferred aliphatic fatty alcohols are particularly useful in combination with the volatile liquid silicone oils discussed herein to adjust the average solubility of the liquid base material, c. Non-polar, Non-volatile Emollients In addition to the liquids discussed above, the liquid base material can optionally include non-volatile, non-polar emollients which tend to improve product cosmetics. Typical non-volatile, non-polar emollients are disclosed, for example, in Cosmetics, Science, and Technology, Vol. 1 , 27-104 edited by Balsam and Sagarin, 1972; U.S. Pat. 4,202,879 issued to Shelton on May 13, 1980; and U.S. Pat. 4,816,261 issued to Luebbe et al. on March 28, 1989.get good dissolution.

II Additional Components for Hair Treating Compositions, Antiperspirant and/or Deodorant Compositions

A wide variety of additional components can be employed in the hair treating compositions, antiperspirant and/or deodorant compositions herein. Non-limiting examples include the following: 1. Deodorant Active Ingredients

Suitable types of deodorant actives include antimicrobial ingredients such as bactericides and fungicides. Exemplary deodorant actives include quaternary ammonium compounds such as cetyl-trimethylammonium bromide, cetyl pyridinium chloride, benzethonium chloride, diisobutyl phenoxy ethoxy ethyl dimethyl benzyl ammonium chloride, sodium N-lauryl sarcosine, sodium N- palmethyl sarcosine, lauroyl sarcosine, N-myristoyl glycine, potassium N-lauryl sarcosine, stearyl, trimethyl ammonium chloride, sodium aluminum chlorohydroxy lactate, tricetylmethyl ammonium chloride, 2,4,4^,-trichlorio-2'-hydroxy diphenyl ether, diaminoalkyl amides such as L-lysine hexadecyl amide, heavy metal salts of citrate, salicylate, and piroctose, especially zinc salts, and acids thereof, heavy metal salts of pyrithione, especially zinc pyrithione and zinc phenolsulfate.

Other deodorant actives include odor absorbing materials such as carbonate and bicarbonate salts, e.g. as the alkali metal carbonates and bicarbonates, ammonium and tetraalkyiammonium carbonates and bicarbonates, especially the sodium and potassium salts.

Mixtures of deodorant actives are also contemplated and intended to be encompassed herein. 2. Antiperspirant Actives The compositions of the present invention can also contain an astringent antiperspirant active. These actives are typically used at levels from about 0.5% to about 60%, preferably from about 5% to about 35%, in, e.g., an antiperspirant gel stick composition. This active can be incorporated either in solubilized or particulate form. These weight percentages are calculated on an anhydrous metal salt basis (exclusive of, e.g., glycine, the salts of glycine, or other complexing agents). Such materials include, for example, many aluminum or zirconium astringent salts or complexes and are well known in the antiperspirant art.

The antiperspirant active is preferably in particulate form wherein the surface area of the active is relatively low. The surface area of the antiperspirant active can be reduced by increasing the size and density of the active particles. Consequently, the particulate antiperspirant active preferably has a density which is preferably greater than about 0.7 g/cm3 and an average particle size (as measured by a Coulter Multisizer 11 manufactured by Coulter Corporation, Haleah, Florida) greater than about 10 microns; more preferably, greater than about 30 microns; and most preferably, greater than about 40 microns. Such preferred materials can be purchased from Westwood Chemical Company, Middletown, N.Y. under the trade name Westchlor® ZR. Suitable antiperspirant active is disclosed, for example in U.S. Patent 4,147,766 which issued on April 3, 1979 to Kozischek.

Any aluminum astringent antiperspirant salt or aluminum and/or zirconium astringent complex can be employed herein. Salts useful as astringent antiperspirant salts or as components of astringent complexes include aluminum halides, aluminum hydroxy-halides, zirconyl oxyhalides, zirconyl hydroxy-halides, and mixtures of these materials.

Aluminum salts of this type include aluminum chloride and the aluminum hydroxyhalides having the general formula Al2(OH) x Q y .XH2O where Q is chlorine, bromine or iodine; where x is from about 2 to about 5, and x+y = about

6, and x and y do not need to be integers; and where X is from about 1 to about 6. Aluminum salts of this type can be prepared in the manner described more fully in U.S. Patent 3,887,692 issued to Gilman on June 3, 1975, and U.S. Patent 3,904,741 issued to Jones and Rubino on September 9, 1975.

The zirconium compounds which are useful in the present invention include both the zirconium oxy salts and zirconium hydroxy salts, also referred to as the zirconyl salts and zirconyl hydroxy salts. These compounds may be represented by the following general empirical formula:

ZrO(OH)2-_nzBz wherein z may vary from about 0.9 to about 2 and need not be an integer, n is the valence of B, 2-nz is greater than or equal to 0, and B may be selected from the group consisting of halides, nitrate, sulfamate, sulfate, and mixtures thereof. Although only zirconium compounds are exemplified in this specification, it will be understood that other Group IVB metal compounds, including hafnium, can be used in the present invention.

As with the basic aluminum compounds, it will be understood that the above formula is greatly simplified and is intended to represent and include compounds having coordinated and/or bound water in various quantities, as well as polymers, mixtures and complexes of the above. As will be seen from the above formula, the zirconium hydroxy salts actually represent a range of compounds having various amounts of the hydroxy group, varying from about 1.1 to only slightly greater than zero groups per molecule.

Several types of antiperspirant complexes utilizing the above antiperspirant salts are known in the art. For example, U.S. Patent 3,792,068 issued to Luedders et al. on February 12, 1974 discloses complexes of aluminum, zirconium and amino acids, such as glycine. Complexes such as those disclosed in the Luedders et al. patent and other similar complexes are commonly known as ZAG. ZAG complexes are chemically analyzable for the presence of aluminum, zirconium and chlorine. ZAG complexes useful herein are identified by the specification of both the molar ratio of aluminum to zirconium (hereinafter "AI:Zr" ratio) and the molar ratio of total metal to chlorine (hereinafter "Metal:CI" ratio). ZAG complexes useful herein have an AI:Zr ratio of from about 1.67 to about 12.5 and a Metal:CI ratio of from about 0.73 to about 1.93.

Preferred ZAG complexes are formed by (A) co-dissolving in water (1) one part Al2(OH)g__mQ_m, wherein Q is an anion selected from the group consisting of chloride, bromide and iodide, and m is a number from about 0.8 to about 2.0;

(2) x parts ZrO(OH)2-_aQ_a-nH2θ, where Q is chloride, bromide or iodide; where a is from about 1 to about 2; where n is from about 1 to about 8; and where x has a value of from about 0.16 to about 1.2;

(3) p parts neutral amino acid selected from the group consisting of glycine, dl-tryptophane, dl-b-phenylalanine, dl-valine, dl-methionine and b-alanine, and where p has a value of from about 0.06 to about 0.53;

(B) co-drying the resultant mixture to a friable solid; and (C) reducing the resultant dried inorganic-organic antiperspirant complex to particulate form.

A preferred aluminum compound for preparation of such ZAG type complexes is aluminum chlorhydroxide of the empirical formula Al2(OH)5CI.2H2θ. Preferred zirconium compounds for preparation of such ZAG-type complexes are zirconyl hydroxychloride having the empirical formula ZrO(OH)CI.3H2θ and the zirconyl hydroxyhalides of the empirical formula ZrO(OH)2-aCl2-nH2θ wherein a is from about 1.5 to about 1.87, and n is from about 1 to about 7. The preferred amino acid for preparing such ZAG-type complexes is glycine of the formula CH2(NH2)COOH. Salts of such amino acids can also be employed in the antiperspirant complexes. See U.S. Patent 4,017,599 issued to Rubino on April 12, 1977.

A wide variety of other types of antiperspirant complexes are also known in the art. For example, U.S. Patent 3,903,258 issued to Siegal on September 2, 1975 discloses a zirconium aluminum complex prepared by reacting zirconyl chloride with aluminum hydroxide and aluminum chlorhydroxide. U.S. Patent 3,979,510 issued to Rubino on September 7, 1976 discloses an antiperspirant complex formed from certain aluminum compounds, certain zirconium compounds, and certain complex aluminum buffers. U.S. Patent 3,981 ,896 issued to Pauling on September 21 , 1976 discloses an antiperspirant complex prepared from an aluminum polyol compound, a zirconium compound and an organic buffer. U.S. Patent 3,970,748 issued to Mecca on July 20, 1976 discloses an aluminum chlorhydroxy glycinate complex of the approximate general formula [Al2(OH)₄CI][H2CNH₂COOH].

C Article of Manufacture for Consumer Products Containing Malodor Reducing Composition

The following description is non-limiting examples for manufacturing consumer products, especially for fabric freshening compositions, of the present invention. Other conventional article of manufacture known to those skilled in the art can be included as the article of manufacture for consumer product of the present invention . SPRAY DISPENSER The article of manufacture herein comprises a spray dispenser. The composition of the present invention (e.g., fabric freshening composition) is placed into a spray dispenser in order to be distributed onto the surface of the material (e.g., fabric). Said spray dispenser is preferably any of the manually activated means for producing a spray of liquid droplets as is known in the art, e.g. trigger-type, pump-type, non-aerosol self-pressurized, and aerosol-type spray means. The spray dispenser herein does not normally include those that will substantially foam the clear, aqueous odor absorbing composition.

The spray dispenser can be an aerosol dispenser. Said aerosol dispenser comprises a container which can be constructed of any of the conventional materials employed in fabricating aerosol containers. The aerosol dispenser utilizes a pressurized sealed container from which the clear, aqueous odor- absorbing composition is dispensed through a special actuator/valve assembly under pressure. The aerosol dispenser is pressurized by incorporating therein a gaseous component generally known as a propellant. Common aerosol propellants, e.g., gaseous hydrocarbons such as isobutane, and mixed halogenated hydrocarbons, which are not preferred. Halogenated hydrocarbon propellants such as chlorofluoro hydrocarbons have been alleged to contribute to environmental problems. Preferred propellants are compressed air, nitrogen, inert gases, carbon dioxide, etc. A more complete description of commercially available aerosol-spray dispensers appears in U.S. Pat. Nos.: 3,436,772, Stebbins, issued April 8, 1969; and 3,600,325, Kaufman et al., issued August 17, 1971 ; both of said references are incorporated herein by reference.

For a fabric freshening composition, preferably, the spray dispenser is a non-aerosol, manually activated, pump-spray dispenser. Said pump-spray dispenser comprises a container and a pump mechanism which securely screws or snaps onto the container. The container comprises a vessel for containing the aqueous odor-absorbing composition to be dispensed.

The pump mechanism comprises a pump chamber of substantially fixed volume, having an opening at the inner end thereof. Within the pump chamber is located a pump stem having a piston on the end thereof disposed for reciprocal motion in the pump chamber. The pump stem has a passageway there through with a dispensing outlet at the outer end of the passageway and an axial inlet port located inwardly thereof.

The container and the pump mechanism can be constructed of any conventional material employed in fabricating pump-spray dispensers, including, but not limited to: polyethylene; polypropylene; polyethyleneterephthalate; blends of polyethylene, vinyl acetate, and rubber elastomer. A preferred container is made of clear, e.g., polyethylene terephthalate. Other materials can include stainless steel. A more complete disclosure of commercially available dispensing devices appears in: U.S. Pat. Nos.: 4,895,279, Schultz, issued January 23, 1990; 4,735,347, Schultz et al., issued April 5, 1988; and 4,274,560, Carter, issued June 23, 1981 ; all of said references are herein incorporated by reference.

Such spray dispenser can be a manually activated trigger-spray dispenser. Said trigger-spray dispenser comprises a container and a trigger both of which can be constructed of any of the conventional material employed in fabricating trigger-spray dispensers, including, but not limited to: polyethylene; polypropylene; polyacetal; polycarbonate; polyethyleneterephthalate; polyvinyl chloride; polystyrene; blends of polyethylene, vinyl acetate, and rubber elastomer. Other materials can include stainless steel and glass. A preferred container can be made of clear, e.g. polyethylene terephthalate. The trigger- spray dispenser does not incorporate a propellant gas into the odor-absorbing composition, and preferably it does not include those that will foam the odor- absorbing composition. The trigger-spray dispenser herein is typically one which acts upon a discrete amount of the odor-absorbing composition itself, typically by means of a piston or a collapsing bellows that displaces the composition through a nozzle to create a spray of thin liquid. Said trigger-spray dispenser typically comprises a pump chamber having either a piston or bellows which is movable through a limited stroke response to the trigger for varying the volume of said pump chamber. This pump chamber or bellows chamber collects and holds the product for dispensing. The trigger spray dispenser typically has an outlet check valve for blocking communication and flow of fluid through the nozzle and is responsive to the pressure inside the chamber. For the piston type trigger sprayers, as the trigger is compressed, it acts on the fluid in the chamber and the spring, increasing the pressure on the fluid. For the bellows spray dispenser, as the bellows is compressed, the pressure increases on the fluid. The increase in fluid pressure in either trigger spray dispenser acts to open the top outlet check valve. The top valve allows the product to be forced through the swirl chamber and out the nozzle to form a discharge pattern. An adjustable nozzle cap can be used to vary the pattern of the fluid dispensed.

For the piston spray dispenser, as the trigger is released, the spring acts on the piston to return it to its original position. For the bellows spray dispenser, the bellows acts as the spring to return to its original position. This action causes a vacuum in the chamber. The responding fluid acts to close the outlet valve while opening the inlet valve drawing product up to the chamber from the reservoir.

A more complete disclosure of commercially available dispensing devices appears in U.S. Pat. Nos. 4,082,223, Nozawa, issued Apr. 4, 1978; 4,161 , 288, McKinney, issued Jul. 17, 1985; 4,434,917, Saito et al., issued Mar. 6, 1984; and 4,819,835, Tasaki, issued Apr. 11 , 1989; 5,303,867, Peterson, issued Apr. 19, 1994; all of said references are incorporated herein by reference.

A broad array of trigger sprayers or finger pump sprayers are suitable for use with the compositions of this invention. These are readily available from suppliers such as Calmar, Inc., City of Industry, California; CSI (Continental Sprayers, Inc.), St. Peters, Missouri; Berry Plastics Corp., Evansville, Indiana, a distributor of Guala® sprayers; or Seaquest Dispensing, Cary, Illinois.

P. Method of Using Consumer Products Containing Malodor Reducing Composition The consumer products of the present invention are used in conventional ways to provide the desired benefit appropriate to the product such as freshening fabrics, freshening air, freshening and styling hair, freshening and holding hair, freshening and cleaning household products, the like. Such methods of use depend upon the type of composition employed but generally involve application of an effective amount of the product to the fabrics, households, hair or skin, which can then be allowed to remain on the surface of fabrics/households, (as in the case of fabric freshening compositions/ household cleaning compositions; allowed to remain on the hair (as in the case of spray, mousse, or gel products); or allowed to remain on the skin (as in the case of the antiperspirants/ deodolants). By "effective amount" is meant an amount sufficient to provide the benefit desired.

The aspects and embodiments of the present invention set forth in this document have many surprising advantages, including providing malodor reducing compositions which provide malodor impression on surfaces of, e.g., a including fabrics and hair, that are contaminated with environmental odors such as cigarette smoke odors, cooking smoke odors and/or that are wetted with perspiration, air in confined spaces such as bathrooms and kitchens and in consumer products which contain materials which are inherently malodorous, with substantially no odor or faint odor impression on the surfaces after treating the compositions.

Procedures of Odor Evaluations:

Odor evaluations for three different kinds of malodors on fabric were conducted by following procedures.

Preparations for Fabric Swatches with Different Kinds of Malodors: • Cigarette Smoke Odor:

1. Prepare swatches of white poly-cotton (60 cotton/40 polyester) fabric. (Size: 8 inch x 8 inch, weight: ~8.4g).

2. Place the lighted one cigarette in a lidded container.

3. Hang the swatches on the lid of the container over the cigarette in the trash can.

4. Time to 60 seconds.

5. Close the lid tightly and let the smoke absorbed by the swatches.

6. Take the swatches out from the can and store them in a plastic bag.

7. Store the swatches in a plastic bag to keep the odor and avoid contamination until technical evaluations.

• Cooking Smoke Odor:

1. Prepare swatches of white poly-cotton (60 cotton/40 polyester) fabric. (Size: 8 inch x 8 inch, weight: ~8.4g). 2 Place the swatches on a table counter in a restaurant which is filled with cooking smoke for one hour while cooking so the odor from cooking can be absorbed by the swatches. 3. Store the swatches in a plastic bag to keep the odor and avoid contamination until technical evaluations. • Body (Worn T-shirt) Odor:

1. Prepare 100% cotton T-shirts.

2. T-shirt are worn for a whole day so the odor of body can be absorbed by the T-shirt.

3. Cut the worn T-shirt into 8 inch x 8 inch size swatches.

4. Store the swatches in a plastic bag to keep the odor and avoid contamination until technical evaluations.

Technical Odor Evaluations: (Done by at least three sensory evaluators in an odor free room.)

1. Smell all the swatches to measure malodor impact using a 0-100 scale below and select the one with the same impact.

2. Spray 0.6 g of Febreze on the four corners and center of a swatch. 3. Smell swatch to measure perfume and malodor impact for "wet fabric" using a 0-100 odor impact scale. (See the definition of the scale below.)

4. Hang swatches on a drying line in an odor-free room.

5. Smell swatch 1.5 hours later to measure perfume and malodor impact for "dry down" using the 0-100 odor impact scale.
