(2) from 0.1% to 20% by weight, based on the total solids, of a water-soluble or water-dispersible polyamide reaction product of (a) a polyalkyleneimine having an average molecular weight of from 300 to 6000 selected from the group consisting of polyethyleneimines and polypropyleneimines and (b) an organic THE PRIOR ART It is known to add to washing and cleaning compositions which contain surface-active compounds, substances which improve the dirt-carrying capacity of the washing liquors. Such substances, subsequently called graying inhibitors, prevent re-absorption of the detached dirt on the cleaned surfaces. These substances are mostly polyanionic polymers, which are prepared either from natural substances such as cellulose, gelatine or glue or by polymerization of vinyl compounds such as acrylic acid, methacrylic acid, maelic acid and mixtures of these with copolymerizable olefins. The polysulfonates of vinyl polymers have also already been recommended as graying inhibiting additions to washing and cleaning compositions. Of these compounds, however, only carboxymethylcellulose has attained relatively great technical importance, chiefly since it surpasses all known synthetic polymers in its graying-inhibiting action. Carboxymethylcellulose and the said synthetic polymers, however, have the disadvantage that their graying-preventing action is restricted to cellulosic fibers. They are largely inactive in the washing of synthetic fibrous material, chemically altered cellulose or finished cottons. This disadvantage becomes specially noticeable in the case of white textiles from polyester or polyolefin fibers, non-iron cottons and mixed fabrics from the said synthetic fibers and cellulose 3,663,444 Patented May 16, 1972 fibers which, in spite of frequent washings, may become gray and consequently of poor appearance.

OBJECTS OF THE INVENTION An object of the present invention is to develop a composition which may not have the aforesaid disadvantages.

Another object of the invention is the development of a washing and cleansing composition with improved dirtcarrying capacity consisting of essentially of (1) a surface-active detergent composition,

(2) from'-'0cl%-to..2.0%.-by weight, based on the total solids, of a water-soluble or water-dispersible polyamide reaction product of (a) a polyalkyleneimine having an average molecular weight of from 300 to 6000 selected from the group consisting of polyethyleneimines and polypropyleneimines and (b) an organic polycarboxylic acid having from 2 to 10 carbon atoms selected from the group consisting of oxalic acid, alkanedioic acids, alkanetrioic acids, alkenedioic acids, benzenedicarboxylic acids, benzenetricarboxylic acids, cyclohexanedicarboxlic acids, cyclohexanetricarboxylic acids, hydroxyalkanedioic acids, hydroxyalkanetrioic acids, polyoxyalkanedioic acids, polythioalkanedioic acids, polyaminoalkanedioic acids, and polyaminoalkanetrioic acids, the molar ratio of alkyleneimine unit to organic polycarboxylic acid being from :1 to 5:1, and

( 3) optionally a non-surfaceacti-vebuilder saLt and aeorm pound with an intensified cleaning action.

These and other objects of the invention will become more apparent as the description thereof proceeds.

DESCRIPTION OF THE INVENTION The invention provides a washing and cleansing composition with improved dirt-carrying capacity especially for synthetic fibers comprising a surface-active detergent composition, froml0.1.%- to, 20%. by weight, based on the total solids, of a water-soluble or water-dispersible polyamide, which is obtained by reaction of a polyethyleneimine or 'polypropyleneimine of average molecular weight of from 300 to 6000 with a-di-, and/or tri-carboxylic acid containing 2 to 10 carbon atoms in the molecule and in which the molar ratio of alkyleneimine unit to polycarboxylic acid is from 100:1 to 5:1, and 0ptionally a non-surface-active builder salt and a compound with an intensified cleaning action.

The polyamides contained in the new washing compositions are obtainable by known method. It is preferred to use polyethyleneimines as starting substances which have an average molecular weight from 300 to 6000, especially 500 to 3000. Suitable polycarboxylic acids having 2 to 10 carbon atoms are aliphatic or cycloaliphatic, saturated or unsaturated, as well as aromatic, diand tricarhoxylie acids; such as alkanedioic acids carboxylic acids are polyoxyalkanedioic acids such as diglycolic acid; polythioalkanedioic acids such as thiodiglycolic acid; polyaminoalkanedioic acids such as iminodiacetic acid and polyaminoalkanetrioic acids such as nitrilotriacetic acid. Mixtures of the above-mentioned carboxylic acids may also be used. The reaction products of polyethyleneimine with dicarboxylic acids are preferred.

The preparation of the polyamides is carried out in known way, for example by heating the mixture of acid and polyalkyleneimine for several hours in vacuo or in the presence of a solvent from which the water formed in the reaction can be azeotropically distilled. Instead of the free dior tri-carboxylic acids, their derivatives capable of reaction, for example the acid anhydrides, chlorides or bromides, may also be used as starting substances. The amounts of dior tri-carboxylic acid used per alkyleneimine unit are preferably such that at least one mol of a dior tri-carboxylic acid is associated with one macromolecule consisting of polyalkyleneimine. The molar ratio of alkyleneimine unit to polyvalent carboxylic acid in the preferred range amounts to 50:1 to :1, depending upon the average molecular weight of the polyalkyleneimine.

The polyamides prepared in the manner indicated have a resinous consistency and are soluble or dispersible in water or in solutions of washing compositions. They may still contain minor amounts of unreacted starting substances, which can be removed by extraction with organic solvents and if desired again used in the reaction. Since these compounds do not affect the cleaning properties of the compositions, however, their separation is unnecessary. Owing to the insolubility of the high molecular weight compounds in organic solvents and on account of their content of low-molecular weight fractions, the usual methods of molecular weight determination cannot be used. The degree of polymerization and molecular weight of the final polyamides therefore cannot be given with sufiicient accuracy.

In addition to the polyamides, the washing and cleaning compositions according to the invention contain surface-active substances customary in such compositions such as anionic, non-ionic or amphoteric detergent substances. Further, non-surface-active inorganic and/ or organic builder salts may be present, as well as compounds which increase the cleaning capacity of the compositions or the degree of whiteness of the treated textiles.

Suitable detergent substances are anionic compounds of the sulfonate or sulfate type, for example alkylbenzene sulfonates; especially n-dodecylbenzenesulfonate, and also olefinsulfonates such as are obtained, for example, by sulfonation of primary or secondary aliphatic monoolefins with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis. Alkylsulfonates, such as are obtainable from n-alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization, or by addition of bisulfite to olefins, may also be used. In addition, a-sulfo-fatty acid esters, primary and secondary alkyl sulfates and the sulfates of ethoxylated or propoxylated higher molecular weight alcohols are suitable.

Further compounds of this anionic class which, if desired, may be present in the washing compositions, are the higher molecular weight sulfated partial ethers and partial esters of polyhydric alcohols, such as the alkali metal salts of the monoalkyl ethers or mono-fatty acid esters of glycerinemonosulfuric acid ester or 1,2-dihydroxypropanesulfonic acid respectively. Sulfates of ethoxylated or propoxylated fatty acid amides and alkylphenols and also fatty acid taurides and fatty acid isothionates are also suitable.

Further suitable anionic detergent substances are alkali metal soaps of higher fatty acids of natural or synthetic origin, for example the sodium soaps of coconut, palm kernel or tallow fatty acids. The amphoteric detergent substances may be alkylbetaines and especially alkylsulfobetaines, for example 3-(N,N-dimethyl-N-alkylammonium)-propane-l-sulfonate and 3-(N,N-dimethyl-N-alkylammonium) -2-hydroxypropanel-sulfonate.

The anionic detergent substances may be present as the sodium, potassium and ammonium salts or as salts of organic bases, such as mono-, di or tri-ethanolamine. When the said anionic and amphoteric compounds contain an aliphatic hydrocarbon residue, this should preferably be a straight chain and contain 8 to 22 carbon atoms. In compounds with an araliphatic hydrocarbon residue the preferably unbranched alkyl chains contain an average of 6 to 16 carbon atoms.

The most suitable non-ionic surface-active detergent substances are 01 glyegletherfierivatives of alcohols, fatty acids and a kylphenols which contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the hydrocarbon residue. Particularly suitable are polyglycol ether derivatives which contain from 5 to 15 ethylene glycol ether groups and of which the hydrocarbon residues are derived from straight chain primary alcohols having 12 to 18 carbon atoms or from alkylphenols with a straight alkyl chain containing 6 to 14 carbon atoms. By addition of 3 to 15 mols of propylene oxide to a last-named polyethylene glycol ether or by conversion into the acetals, washing substances are obtained which are marked by a particularly low foaming power.

Further suitable non-ionic detergent substances are the water-soluble adducts, containing 20 to 250 ethylene glycol ether groups and 10 to propylene glycol ether groups of polyethylene oxide to polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol with 1 to 10 carbon atoms in the alkyl chain. The said compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Non-ionic compounds of the amineoxide and sulfoxide type which, if desired, may also be ethoxylated, are also utilizable.

Suitable mixing components are also inorganic cleaning salts or builders, especially condensed phosphates such as pyrophosphates, triphosphates, tetraphosphates, trimetaphosphates, tetrametaphosphates and more highly condensed phosphates, in the form of the neutral or acid sodium, potassium or ammonium salts. Alkali metal triphosphates and their mixtures with pyrophosphate are preferably used. Further silicates may be used, especially sodium silicate, in which the ratio of Na OzsiO amounts to 1:3.5 to 1:1.

The condensed phosphates may also be wholly or partly replaced by organic nitrogenor phosphorus-containing complex-forming substances with a cleaning action. These compounds include the alkali metal or ammonium salts of nitrilotriacetic acid, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid and the higher homologues of the said aminopolycarboxylic acids. Suitable homologues may be prepared, for example, by polymerization of an ester, amide or nitrile of N-acetic acid aziridine and subsequent saponification to the carboxylic acid salts, or by reaction of polyamines 'with a molecular weight of 500 to 100,000 with salts of chloroacetic acid or bromoacetic acid in an alkaline medium. Further suitable aminopolycarboxylic acids are poly-(N-B-propionic acid)- ethyleneimines of average molecular weight from 500 to 200,000 which are obtainable analogously to the N-acetic acid derivatives. Phosphorus-containing complex-forming substances which may be used are the alkali metal and ammonium salts of aminopolyphosphonic acids, especially aminotri-(methylenephosphonic acid), ethylenediaminetetra-( methylenephosphonic acid), 1-hydroxyethane-1,ldiphosphonic acid, methylenediphosphonic acid, ethylenediphosphonic acid and the higher homologues of the said polyphosphonic acids. Mixtures of the aforesaid complexforming substances may also be used.

Further suitable mixing components are neutral salts such as sodium sulfate and sodium chloride, and substances for regulating the pH such as sodium or potassium bicarbonates, borates and hydroxides, and also acids such as lactic acid and citric acid. The quantity of alkaline-reacting substances inclusive of the alkali metal silicates and phosphates should be such that the pH of a liquor suitable for coarse washing amounts to 9 to 12 and for fine washing amounts to 6 to 9.

By suitable combination of different surface-active detergent substances and builder salts, increased actions may be obtained in many cases, for example, an improved washing power or a reduced foaming capacity. Such improvements are possible, for example, by combination of anionic with non-ionic and/or amphoteric compounds, by combination of different non-ionic compounds or by mixtures of detergents of the same type which differ in respect to the number of carbon atoms or the number and position of the double bonds or branchings of the chains in the hydrocarbons. Likewise synergistically-acting mixtures of inorganic and organic builder salts maye be used or combined with the aforesaid mixtures.

The compositions may contain oxygen-yielding bleaching agents, such as hydrogen peroxide, alkali metal perborates, alkali metal percarbonates, alkali metal perphosphates urea perhydrate and alkali metal pgrgulat or active chlorine-containing compouns, I I rmtal hypochlorites, chlorinated trisodium phosph te and chlorinated cyanuric acid or its alkali metal salts, according to the purpose of u Suitable optical brighteners are those of the bis(tri- "aiinyl)-4,4-diaminostilbenedisulfonic acid type of the formula pre comppunds my be-presenw cially 2 to 4 carbon atoms, and in the heterocyclic ring Some of these brighteners are to be regarded as transitional types to the cotton brighteners as regards their afiinity for the fiber, for example, the brightener in which R; equals NHC H The compound 4,4-bis-(4- phenyl-vicinal-triazolyl-Z-)-stilbenedisulfonic acid 2,2 also belongs to the cotton brighteners of the diaminostilbenesulfonic acid type.

In this formula Ar and Ar' signify aryl residues such as phenyl, diphenyl or naphthyl, which may be substituted by substituents such as hydroxy, alkoxy, hydroxyalkyl, amino, alkylamino, acylamino, carboxyl, sulfonic acid and sulfonamide groups or halogen atoms. It is preferred to use a 1,3-diarylpyrazoline derivative in which the residue Ar represents a p-sulfonamidophenyl group and the residue Ar represents a p'chlorophenyl group. Besides this, for brightening of other types of fibers, suitable white toners may also be present, for example, those of the type of the naphthotriazolestilbenesulfonates, ethylenebis benzimidazoles, ethylene bis benzoxazoles, thiophene bis benzoxazoles, dialkylaminocoumarins and cyanoanthracene. These brighteners or their mixtures may be present in the compositions in amounts fromv 0.01 to 1.5% by weight, preferably 0.1 to 1% by weight.

For the purpose of increasing the dirt carrying power, further known graying inhibitors may be added, such as sodium celluloseglycollate or the water-soluble alkali metal salts of polyesters and polyamides or vinyl polymers containing free carboxyl groups. These include the polyesters or polyamides from triand tetra-carboxylic acids and dihydric alcohols or diamines, and polymeric acrylic, methacrylic, maleic, fumaric, itaconic, citraconic and aconitic acids as well as the mixed polymerizates of the said unsaturated carboxylic acids or their copolymers with olefins.

Compositions which are intended for use in drum washing machines suitably contain known foam-inhibiting agents, as, for example, saturated fatty acids with 20 to 24 carbon atoms, or their alkali metal soaps, or triazine derivatives which are obtainable by the reaction of 1 mol of cyanuric chloride with 2 to 3 mol of an aliphatic, straight, branched or cyclic chain, primary monoamine or by propoxylation or butoxylation of melamine.

For further improvement of the dirt-loosening properties of the compositions according to the invention, these may also contain Whe class of proteases, lipases and amylases. The enzymes may be of animal and vegetable origin, for example may be obtained from digestive ferments or yeasts such as pepsin, pancreatin, trypsin, papain, catalase and diastase. Enzymic active substances obtained from strains of bacteria or fungi, such as Bacillus subtilis and Streptomyces griseus, are preferably used which are relatively stable towards alkali, per-compounds and anionic detergent substances and are not appreciably inactivated even at temperatures between 45 and 70 C.

The washing and cleaning compositions may be present in liquid, pasty or solid, for example pulverulent, granulated or lump form. Liquid preparations may contain solvents miscible with water, especially ethanol and isopropanol, and also solution aids such as the alkali metal salts of benzene-, toluene-, xylene-, or ethylbenzenc-sulfonic acids. To increase the foaming capacity and to improve the compatibility with the skin, alkylolamides such as fatty acid monoand di-ethanolamides may be added if desired. Moreover, the mixtures may contain dyestufis and perfumes, bactericides, substances with a freshening action, and fillers, for example urea.

The preparation of the compositions according to the invention may be effected in the usual way by mixing, granulatmg or spray drying. If enzymes are used, it is advisable to mix these with non-ionic detergent substances and possibly perfumes or to disperse them in the melt of a salt containing water of crystallization, for example Glaubers salt, and then to unite these prior mixtures with the remaining powder components. In this way the enzymes are cemented with the other particles of powder so that the mixtures do not tend to form dust or to separate into their components.

The qualitative and quantitative composition of the preparations according to the invention depend largely on their field of use. The content of polyamide from polycarboxylic acid and polyalkyleneimine amounts to 0.1% to 20%, preferably 0.2% to 10% by weight based on total solids. The difference of 80% to 99.9%, preferably 90% to 99.8% by weight is composed of other washing agent components, the quantitative composition of which may correspond to the following scheme (data in percent by weights):

1% to 40% of at least one compound from the class of the anionic, non-anionic and amphoteric surface-active compounds, preferably as utilizable in neutral to alkaline textile washing baths;

10% to 80% of at least one non-surface-active builder salt with a cleaning intensifying action or a complexforming action;

10% to 50% of a pre-compound, especially sodium perborate, anhydrous or containing water of crystallization or its mixtures with stabilizers and activators;

0.1% to 20% of other assistants and additives.

The surface-active compounds may consist of up to 100%, preferably 5% to 70%, of anionic surface-active compounds of the sulfonate and/or sulfate type; up to 100%, preferably 5% to 40%, of non-ionic surface-active compounds of the polyglycol ether type; and up to 100%, preferably 10% to 50%, of soap.

The builder salts may be composed of up to 100%, preferably 25% to 95%, of alkali metal triphosphates and their mixtures with alkali metal pyrophosphates; up to 100%, preferably 5% to 50%, of an alkali metal salt of a complex-forming substance from the class of polyphosphonic acids, nitrilotriacetic acid, ethylenediaminetetraacetic acid; and up to 100%, preferably 5% to 75% of at least one compound from the class of alkali metal silicates, alkali metal carbonates and alkali metal borates.

The other assistants and additives include, besides the optical brighteners, especially the foam inhibitors which may be present in the compositions according to the invention in a quantity up to 5%, preferably in a quantity of from 0.2% to 3%, and also the enzymes which may be present in a quantity up to 5%, preferably 0.2% to 3%, and the additional graying inhibitors, the amount of which may be up to 5%, preferably.0.2 t,o ,3%,

The present invention will be further described by way of reference to the following specific examples which are not deemed limitative in any respect.

0.5 to 3% of sodium celluloseglycollate Examples 2-16 The graying inhibiting action of the compounds described in the following examples was tested by the known soil redeposition method. In this method, 4 small pieces from the fabric to be examined having a total weight of 8.3 gm. together with 1.3 gm. of an artificially soiled cotton yarn are washed three times for 30 minutes each time in a laboratory washing machine. (Launder- Ometer," registered trademark.) The reflection value is then found with a photometer (Elrepho, registered trademark) using Filter N0. 6.

The combination of dust and skin fat similar to that found in practice used for soiling the cotton yarn consisted of a mixture of kaolin, black iron oxide, soot and synthetic skin fat (comprising /3 fatty acids, /3 fat and V3 hydrocarbons). After soiling, the cotton yarn contained about 1 1% of pigments and about 2% of skin fat.

A prior art washing preparation was used of the following composition (in percent by weight):

8% of n-dodecylbenzenesulfonate (Na salt) 3% of oleyl alcohol with 10 ethylene glycol ether groups 3% of Na soap of saturated C to C fatty acids 40% of pentasodium tripolyphosphate 22% of sodium perborate 3.5% of sodium silicate (Na O:SiO =1:3.3)

2.5% of magnesium silicate 0.2% of Na nitrilotriacetate 0.3% of an optical brightener 4% of graying inhibitors, as defined below, were added to this preparation and it was made up to 100% with sodium sulfate.

The concentration of the washing composition used was 5 gm. per liter, and the hardness of the water was 10 German hardness. The textile samples consisting of synthetic fabric (polyester fiber) and mixed fabric (polyester fiber with finished cotton and also polypropylene fiber with cotton) were washed at 60 C. and that of finished cotton was washed at C. The proportion by weight of textile material to wash liquor was 1:30. After a washing period of 30 minutes the samples were rinsed four times with distilled water. After three washing treatments the degree of whiteness of the samples was determined photometrically.

For the preparation of the graying inhibitors according to the invention, a solution of the polyethyleneimine of the average molecular weight indicated and polycarboxylic acid, as indicated, in xylene was heated at the boil until 2 mols of water had been azetropically distilled per mol of polyvalent carboxylic acid. The resin remaining after distilling the solvent was directly utilizable without further treatment.

The average molecular weight of the polyethyleneimine used, the polycarboxylic used, and the molar ratio (mols of ethyleneimine units per mol of dior tri-carboxylic acid) are given in the following Table I, as well as the remission values of the washed textiles. For comparison, washing experiments were carried out without use of a graying inhibitor and with use of sodium celluloseglyeolrespectively, The results show afiisffifitfihperiority of the SltlOIlS according to the invention.
