Description

LIQUID DETERGENT COMPOSITIONS COMPRISING

PROTEASE AND ENCAPSULATED LIPASE

FIELD OF THE INVENTION

The present invention is in the field of cleaning compositions.

BACKGROUND OF THE INVENTION

An important purpose of detergents and/or cleaning compositions is to remove soils and stains from fabrics to achieve consumer perceivable cleaning benefit. Enzymes are especially useful cleaning components and particularly lipase enzymes as they are effective at removing oily soils. However they can be difficult to formulate because most liquid detergent compositions comprise protease enzymes. Lipase enzymes are particularly vulnerable to proteases and may be degraded by the presence of other components of the detergent composition so that on storage, the lipase tends to be gradually degraded. Many efforts have been made to alleviate this problem, for example by separating the protease or lipase, however this generally does not solve the problem of formulating with both enzymes.

SUMMARY OF THE INVENTION

The present invention relates to a liquid detergent composition comprising a protease enzyme, a lipase enzyme and from 2 to 80 wt%, preferably from 5 to 60 wt% non-soap surfactant system wherein the surfactant system comprises (i) anionic surfactant and (ii) nonionic surfactant wherein the weight ratio of (i) to (ii) is from 1:1 to 99:1, characterized in that in the composition at least 65 wt% of the lipase enzyme is present in an encapsulate, wherein the encapsulate comprises a shell wherein the shell is insoluble in the liquid detergent composition but which dissolves upon dilution of the liquid detergent composition in the wash liquor.

Preferably the weight ratio of anionic surfactant (i) to nonionic surfactant (ii) is from 51:49 to 99: 1, or preferably 55:45 to 99:1, preferably from 3:2 to 9:1.

The cleaning compositions may have a form selected from liquid, powder, single-phase or multi-phase unit dose or pouch form, tablet, gel, paste, bar, or flake. In a preferred embodiment of the present invention, the cleaning composition of the present invention is a liquid laundry or dish detergent composition, which is in a single phase or multiphase unit dose form as encapsulated by a single compartment or multi-compartment water-soluble pouch, e.g., formed by a water-soluble polymer such as polyvinyl alcohol (PVA) or copolymers thereof. More preferably, the cleaning composition of the present invention is a liquid laundry detergent composition designated for treating fabrics to achieve improved whiteness maintenance benefit.

As used herein, the term "laundry detergent" means a liquid or solid composition, and includes, unless otherwise indicated, granular or powder-form all-purpose or "heavy-duty" washing agents, especially cleaning detergents as well as cleaning auxiliaries such as bleach additives or pre-treat types. In a preferred embodiment of the present invention, the laundry detergent is a liqiuid laundry detergent composition.

The present invention provides a cleaning composition, preferably a detergent composition, most preferably a liquid laundry detergent composition, as above and comprising optional additional adjunct ingredients.

The cleaning composition of the present invention can be in any liquid product form, and it can be a laundry detergent composition, a hard surface cleaning composition, a hand dishwashing composition, and an automatic dishwashing composition. The cleaning composition comprises a liquid, and even more preferably it comprises a single phase or multiphase unit dose form, i.e., the liquid cleaning composition is contained in a single compartment or multicompartment water-soluble pouch. In a specific embodiment, the cleaning composition is in a single phase or multiphase unit dose form containing either a liquid automatic dishwashing composition or a liquid laundry detergent composition encapsulated in a single compartment or multi-compartment water-soluble unit dose article or pouch, which is formed, for example, by a water-soluble polymer such as polyvinvyl alcohol (PVA) and/or polyvinylpyrrolidone (PVP).

The laundry treatment composition may be any composition suitable for treating or laundering a fabric.

The liquid detergent composition , preferably laundry detergent of the present invention overall is liquid in nature. That is to say, even though it comprises a solid phase dispersed within a liquid phase, the composition has the nature of a liquid rather than a solid or granular composition. Herein the laundry treatment composition of the present invention, the term 'liquid' encompasses forms such as dispersions, gels, pastes and the like. The liquid composition may also include gases in suitably subdivided form. The term 'liquid laundry treatment composition' refers to any laundry treatment composition comprising a liquid capable of wetting and treating fabric e.g., cleaning clothing in a domestic washing machine. A dispersion for example is a liquid comprising solid or particulate matter contained therein.

The laundry treatment composition can be used as a fully formulated consumer product, or may be added to one or more further ingredient to form a fully formulated consumer product. The laundry treatment composition may be a 'pre-treat' composition which is added to a fabric, preferably a fabric stain, ahead of the fabric being added to a wash liquor.

Preferably, the liquid laundry detergent composition has a viscosity of between 300mPa.s and 700mPa.s, more preferably between 350mPa.s and 600mPa.s at a shear rate of 1000s^"1.

Because phase separation is a constant challenge for liquid laundry detergent compositions, especially when the salt content in such compositions is high, the solvent system of the present invention is particularly designed to minimize the risk of phase separation. Specifically, the solvent system of the present invention is composed mostly of diols, such as ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, pentanediols, and combinations thereof. The diols are present in the liquid laundry detergent composition of the present invention in a total amount ranging from about 2 wt% to about 50 wt%.

Suds Supressor

Compounds for reducing or suppressing the formation of suds may be incorporated into the compositions of the present invention. Suds suppression can be of particular importance in the so-called "high concentration cleaning process" as described in U.S. Pat. No. 4,489,455 and 4,489,574, and in front-loading -style washing machines. A wide variety of materials may be used as suds suppressors, and suds suppressors are well known to those skilled in the art. See, for example, Kirk Othmer Encyclopedia of Chemical Technology, Third Edition, Volume 7, pages 430-447 (John Wiley & Sons, Inc., 1979). Examples of suds supressors include monocarboxylic fatty acid and soluble salts therein, high molecular weight hydrocarbons such as paraffin, fatty acid esters (e.g., fatty acid triglycerides), fatty acid esters of monovalent alcohols, aliphatic C18-C40 ketones (e.g., stearone), N-alkylated amino triazines, waxy hydrocarbons preferably having a melting point below about 100 °C, silicone suds suppressors, and secondary alcohols. Suds supressors are described in U.S. Pat. No. 2,954,347; 4,265,779; 4,265,779; 3,455,839; 3,933,672; 4,652,392; 4,978,471; 4,983,316; 5,288,431; 4,639,489; 4,749,740; and 4,798,679; 4,075,118; European Patent Application No. 89307851.9; EP 150,872; and DOS 2,124,526.

For any detergent compositions to be used in automatic laundry washing machines, suds should not form to the extent that they overflow the washing machine. Suds suppressors, when utilized, are preferably present in a "suds suppressing amount. By "suds suppressing amount" is meant that the formulator of the composition can select an amount of this suds controlling agent that will sufficiently control the suds to result in a low-sudsing laundry detergent for use in automatic laundry washing machines. The compositions herein will generally comprise from 0% to 10% of suds suppressor. When utilized as suds suppressors, monocarboxylic fatty acids, and salts therein, will be present typically in amounts up to 5%, by weight, of the detergent composition.

Many suitable examples of perfumes are provided in the CTFA (Cosmetic, Toiletry and Fragrance Association) 1992 International Buyers Guide, published by CFTA Publications and OPD 1993 Chemicals Buyers Directory 80^th Annual Edition, published by Schnell Publishing Co. It is usual for a plurality of perfume components to be present in the compositions of the invention, for example four, five, six, seven or more. In perfume mixtures preferably 15 to 25 wt% are top notes. Top notes are defined by Poucher (Journal of the Society of Cosmetic Chemists 6(2):80 [1995]). Preferred top notes include rose oxide, citrus oils, linalyl acetate, lavender, linalool, dihydromyrcenol and cis-3-hexanol.

Process of making liquid laundry detergent compositions:

The liquid laundry detergent composition can be formulated and prepared by any suitable process. Such process typically involves mixing the essential and optional ingredients in any desired order to a relatively uniform state, with or without heating, cooling, application of vacuum, and the like, thereby providing cleaning compositions containing ingredients in the requisite concentrations.

Preferably, the external structurant is added, typically as part of a premix, after the incorporation of ingredients that require high shear mixing, in order to minimise damage to the structuring network formed by the external structurant. This is particularly beneficial where the external structurant is a non-polymeric crystalline hydroxyl functional structurant. More preferably, the external structurant is the last ingredient incorporated into the liquid composition. The external structurant is preferably incorporated into the liquid composition using low shear mixing. Preferably, the aqueous structuring premix is incorporated into the liquid composition using average shear rates of less than 1000s^"1, preferably less than 500s^"1, more preferably less than 200s^"1. The residence time of mixing is preferably less than 20s, more preferably less than 5s, more preferably less than Is. The shear rate and residence time is calculated according to the methods used for the mixing device, and is usually provided by the manufacturer. For instance, for a static mixer, the average shear rate is calculated using the equation: pipe

Y =

^pipe

where:

Vj is the void fraction of the static mixer (provided by the supplier)

Dpipe is the internal diameter of the pipe comprising the static mixer elements

vpipe i^{s tne} average velocity of the fluid through a pipe having internal diameter D_pi] calculated from the equation:

Q is the volume flow rate of the fluid through the static mixer.

For a static mixer, the residence time is calculated using the equation: nD_≠pe ²v_fL

residence time = —

where:

L is the length of the static mixer.

The compositions of the invention may be present in the form of a unit dose, for example a tablet or pouch which may comprise liquid and/or solid composition in a water-soluble film.

Water soluble unit dose article

When in the form of a water-soluble unit dose article, the article comprises at least one water-soluble film shaped such that the unit-dose article comprises at least one internal compartment surrounded by the water-soluble film. The at least one compartment comprises the first particle. The water-soluble film is sealed such that the first particle does not leak out of the compartment during storage. However, upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and releases the contents of the internal compartment into the wash liquor.

The compartment should be understood as meaning a closed internal space within the unit dose article, which holds the particle. Preferably, the unit dose article comprises a water-soluble film. The unit dose article is manufactured such that the water-soluble film completely surrounds the particle and in doing so defines the compartment in which the particle resides. The unit dose article may comprise two films. A first film may be shaped to comprise an open compartment into which the particle is added. A second film is then laid over the first film in such an orientation as to close the opening of the compartment. The first and second films are then sealed together along a seal region. The film is described in more detail below.

The unit dose article may comprise more than one compartment, even at least two compartments, or even at least three compartments. The compartments may be arranged in superposed orientation, i.e. one positioned on top of the other. Alternatively, the compartments may be positioned in a side-by-side orientation, i.e. one orientated next to the other. The compartments may even be orientated in a 'tyre and rim' arrangement, i.e. a first compartment is positioned next to a second compartment, but the first compartment at least partially surrounds the second compartment, but does not completely enclose the second compartment.

Alternatively one compartment may be completely enclosed within another compartment.

Wherein the unit dose article comprises at least two compartments, one of the

compartments may be smaller than the other compartment. Wherein the unit dose article comprises at least three compartments, two of the compartments may be smaller than the third compartment, and preferably the smaller compartments are superposed on the larger

compartment. The superposed compartments preferably are orientated side-by-side. In a multi-compartment orientation, the first particle according to the present invention may be comprised in at least one of the compartments. It may for example be comprised in just one compartment, or may be comprised in two compartments, or even in three compartments.

Each compartment may comprise the same or different compositions. The different compositions could all be in the same form, or they may be in different forms.

Water-soluble film

The film is preferably soluble or dispersible in water. The water-soluble film preferably has a thickness of from 20 to 150 micron, preferably 35 to 125 micron, even more preferably 50 to 110 micron, most preferably about 76 micron.

Preferably, the film has a water- solubility of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set out here after using a glass-filter with a maximum pore size of 20 microns:

5 grams ± 0.1 gram of film material is added in a pre-weighed 3L beaker and 2L ± 5ml of distilled water is added. This is stirred vigorously on a magnetic stirrer, Labline model No. 1250 or equivalent and 5 cm magnetic stirrer, set at 600 rpm, for 30 minutes at 30°C. Then, the mixture is filtered through a folded qualitative sintered-glass filter with a pore size as defined above (max. 20 micron). The water is dried off from the collected filtrate by any conventional method, and the weight of the remaining material is determined (which is the dissolved or dispersed fraction). Then, the percentage solubility or dispersability can be calculated.

More preferred polymers are selected from polyacrylates and water-soluble acrylate copolymers, methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin, polymethacrylates, and most preferably selected from polyvinyl alcohols, polyvinyl alcohol copolymers and hydroxypropyl methyl cellulose (HPMC), and combinations thereof. Preferably, the level of polymer in the pouch material, for example a PVA polymer, is at least 60%. The polymer can have any weight average molecular weight, preferably from about 1000 to 1,000,000, more preferably from about 10,000 to 300,000 yet more preferably from about 20,000 to 150,000.

Mixtures of polymers can also be used as the pouch material. This can be beneficial to control the mechanical and/or dissolution properties of the compartments or pouch, depending on the application thereof and the required needs. Suitable mixtures include for example mixtures wherein one polymer has a higher water-solubility than another polymer, and/or one polymer has a higher mechanical strength than another polymer. Also suitable are mixtures of polymers having different weight average molecular weights, for example a mixture of PVA or a copolymer thereof of a weight average molecular weight of about 10,000- 40,000, preferably around 20,000, and of PVA or copolymer thereof, with a weight average molecular weight of about 100,000 to 300,000, preferably around 150,000.

Preferred for use herein are polymers which are from about 60% to about 98% hydrolysed, preferably about 80% to about 90% hydrolysed, to improve the dissolution characteristics of the material.

Preferred films exhibit good dissolution in cold water, meaning unheated distilled water. Preferably such films exhibit good dissolution at temperatures of 24°C, even more preferably at 10°C. By good dissolution it is meant that the film exhibits water- solubility of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set out here after using a glass-filter with a maximum pore size of 20 microns, described above.

Preferred films are those supplied by Monosol under the trade references M8630, M8900, M8779, M8310.

Of the total PVA resin content in the film described herein, the PVA resin can comprise about 30 to about 85 wt% of the first PVA polymer, or about 45 to about 55 wt% of the first PVA polymer. For example, the PVA resin can contain about 50 w.% of each PVA polymer, wherein the viscosity of the first PVA polymer is about 13 cP and the viscosity of the second PVA polymer is about 23 cP.

Naturally, different film material and/or films of different thickness may be employed in making the compartments of the present invention. A benefit in selecting different films is that the resulting compartments may exhibit different solubility or release characteristics.

The film material herein can also comprise one or more additive ingredients. For example, it can be beneficial to add plasticisers, for example glycerol, ethylene glycol, diethyleneglycol, propylene glycol, sorbitol and mixtures thereof. Other additives may include water and functional detergent additives, including surfactant, to be delivered to the wash water, for example organic polymeric dispersants, etc.

The film may be opaque, transparent or translucent. The film may comprise a printed area. The printed area may cover between 10 and 80% of the surface of the film; or between 10 and 80% of the surface of the film that is in contact with the internal space of the compartment; or between 10 and 80% of the surface of the film and between 10 and 80% of the surface of the compartment.

Alternatively, an ink or pigment may be added during the manufacture of the film such that all or at least part of the film is coloured.

The film may comprise an aversive agent, for example selected from bittering agents, pungent agents, emetic agents and mixtures thereof. Bittering agents are a preferred component. Suitable bittering agents include, but are not limited to, naringin, sucrose octaacetate, quinine hydrochloride, denatonium benzoate, or mixtures thereof. Any suitable level of aversive agent may be used in the film. Suitable levels include, but are not limited to, 1 to 5000ppm, or even 100 to 2500ppm, or even 250 to 2000rpm.

METHODS:

A) Method of evaluating the phase stability of fluid laundry detergent compositions:

The phase stability of the composition is evaluated by placing 300ml of the composition in a glass jar for up to a time period of 21 days at 25°C. They are stable to phase splits if, within said time period, (i) they are free from splitting into two or more layers or, (ii) said composition splits into layers, a major layer comprising at least 90%, preferably 95%, by weight of the composition is present.

B) Method of measuring viscosity:

The viscosity is measured using an AR 2000 rheometer from TA instruments using a cone and plate geometry with a 40 mm diameter and an angle of 1°. The viscosity at the different shear rates is measured via a logarithmic shear rate sweep from 0.1 s^"1 to 1200 s^"1 in 3 minutes time at 20°C. Low shear viscosity is measured at a continuous shear rate of 0.05 s^"1.

C) Turbidity (NTU):

The turbidity (measured in NTU: Nephelometric Turbidity Units) is measured using a

Hach 2100P turbidity meter calibrated according to the procedure provided by the manufacture. The sample vials are filled with 15ml of representative sample and capped and cleaned according to the operating instructions. If necessary, the samples are degassed to remove any bubbles either by applying a vacuum or using an ultrasonic bath (see operating manual for procedure). The turbidity is measured using the automatic range selection.

D) Percentage of liquid crystalline phase:

Product is prepared, without the presence of external structurants, and without particulates or other solids which do not dissolve in the product. The product sample is then put in storage in scaled centrifuge tubes for a minimum of 1 day at 5°C and then centrifuged for lh at 4400rpm. After centrifugation, the % liquid crystalline phase is measured as the height of the liquid crystalline phase with a ruler compared to the total height of the centrifuged sample.

E) Method of measuring pH:

The pH is measured, at 25°C, using a Santarius PT-10P pH meter with gel-filled probe

(such as the Toledo probe, part number 52 000 100), calibrated according to the instructions manual.

METHODS OF USING CLENANING COMPOSITIONS

The present invention includes methods of using the cleaning compositions described hereinabove for cleaning soiled material. As will be appreciated by one skilled in the art, the cleaning compositions of the present invention are suited for use in laundry pretreatment applications, laundry cleaning applications, and home care applications.

Such methods include, but are not limited to, the steps of contacting the cleaning compositions in neat form or diluted in wash liquor, with at least a portion of a soiled material and then optionally rinsing the soiled material. The soiled material may be subjected to a washing step prior to the optional rinsing step.

For use in laundry pretreatment applications, the method may include contacting the detergent or cleaning compositions described herein with soiled fabric. Following pretreatment, the soiled fabric may be laundered in a washing machine or otherwise rinsed.

Machine laundry methods may comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of a machine laundry cleaning composition in accord with the invention. An "effective amount" of the cleaning composition means from about 20g to about 300g of product dissolved or dispersed in a wash solution of volume from about 5L to about 65L. The water temperatures may range from about 5°C to about 100°C. The water to soiled material (e.g., fabric) ratio may be from about 1:1 to about 30:1. The compositions may be employed at concentrations of from about 500 ppm to about 15,000 ppm in solution. In the context of a fabric laundry composition, usage levels may also vary depending not only on the type and severity of the soils and stains, but also on the wash water temperature, the volume of wash water, and the type of washing machine (e.g., top-loading, front-loading, top-loading, vertical-axis Japanese-type automatic washing machine).

The cleaning compositions herein may be used for laundering of fabrics at reduced wash temperatures. These methods of laundering fabric comprise the steps of delivering a laundry detergent composition to water to form a wash liquor and adding a laundering fabric to said wash liquor, wherein the wash liquor has a temperature of from about 0°C to about 20°C, or from about 0°C to about 15°C, or from about 0°C to about 9°C. The fabric may be contacted to the water prior to, or after, or simultaneous with, contacting the laundry detergent composition with water.

Another method includes contacting a nonwoven substrate impregnated with an embodiment of the detergent or cleaning composition with soiled material. As used herein, "nonwoven substrate" can comprise any conventionally fashioned nonwoven sheet or web having suitable basis weight, caliper (thickness), absorbency, and strength characteristics. Non- limiting examples of suitable commercially available nonwoven substrates include those marketed under the tradenames SONTARA® by DuPont and POLYWEB® by James River Corp.

Hand washing/soak methods, and combined handwashing with semi-automatic washing machines, are also included. TEST METHODS
