Description
A COMPOSITION AND METHOD FOR TREATING SUBSTRATES Field of the invention
The present invention relates to a composition and a method for treating substrates, such as fabrics; particularly for improved stain removal and better cleaning upon the subsequent wash and also for reduced re-deposition of dirt.
Background of the invention
Fabric stains run the gamut from food spills to household substances and can be of different types; mainly aqueous, oily, particulate and bleachable. Stains are something that people try to avoid, yet they are unavoidable. Nonetheless, people still prefer to wear clothes with lesser stains or no stains at all. In fact, people prefer to avoid stains not just on clothes but in general in kitchens, bathrooms and also on various household surfaces.
Consequently, improved stain removal is one of the constant goals of the detergent industry. There is always an interest to improve the detergency effect, especially on fabric stains. Fabric stains such as particulate stains, especially mud or clay containing iron oxides, aqueous/ bleachable stains such as tea stains or oily stains such as motor oil stains, grease are difficult to remove during main wash. Even if such stains are removed during the wash process, re-deposition of the removed dirt onto the fabric is hard to avoid.
JP09/137378A discloses an antibacterial softener composition comprising a cationic bactericide, a salt of an oolefinsulfonic acid having 20 or more carbon atoms and/or a salt of a dialkylsulfosuccinic acid where the alkyl group has 16 or more carbon atoms, a wax component and optionally a metal chelating agent for better antibacterial property and texture. However, JP09/137378A has not been found to provide improved stain removal or better cleaning upon the subsequent wash and reduced re-deposition of dirt.
US 2003/0073597 disclose a liquid fabric softener composition comprising anionic and cationic surfactants and optionally amphoteric and/or non-ionic surfactants. But said
composition does not provide improved stain removal on the subsequent wash or improved cleaning benefits or reduced re-deposition of dirt.
Laundry compositions have been disclosed in applications WO2010/ 069957, WO201 1/ 151 170 and WO201 1/154225 (all by Unilever). These documents disclose laundry compositions comprising hydroxamate and a surfactant system of anionic and non- ionic surfactants. Similarly, WO2012/062566 (by Unilever) discloses laundry
compositions comprising hydroxamate and a surfactant system of two different types of anionic surfactants. However, these documents have not been found to provide improved aqueous/bleachable, oily and particulate stain removal or better cleaning upon the subsequent wash. Also, the need to reduce or even avoid the re-deposition of removed stains onto the fabric is still desired.
Our co-pending application EP12160157, describes a composition and a method for treating substrates, such as fabrics; particularly to make the substrate stain repellent and easier to clean upon the subsequent wash; and describing that that improved perfume delivery and stain repellence is obtained in compositions comprising a fatty acid, a water soluble salt of aluminium and a non-ionic polymer having a specific HLB value. However it is a long felt need to reduce or even avoid the re-deposition of removed stains onto the fabric.
It is therefore an object of the present invention to provide improved
aqueous/bleachable, oily or particulate stain removal. It is a further object of the present invention to provide improved cleaning upon subsequent wash.
It is yet another object of the invention to reduce re-deposition of dirt. It is still another object of the invention to provide a composition that provides fabric softness.
It is still another object of the invention to provide a composition that provides improved perfume delivery to the fabric.
It is still another object of the present invention to provide a stable composition;
especially a composition that does not phase separate.
Surprisingly, it has been found that improved aqueous, oily or particulate stain removal and reduced re-deposition of dirt can be achieved by depositing a surfactant complex of an anionic and a cationic surfactant, a non-ionic polymer and a chelating agent onto the fabric.
Summary of the invention
Accordingly, in a first aspect, the present invention provides a composition for treating a substrate, said composition comprising 2-22 % by weight of a surfactant complex, selected from cationic and anionic surfactants, wherein the cationic to anionic surfactant weight ratio is in the range of 1 :1 and 6:1 ; 0.5- 10% by weight of a non-ionic polymer having a molecular weight of less than 50ku and a HLB value in the range of 12.5 and 18 and; 1-7% by weight of a chelating agent, selected from hydroxamates of the formula R- CO - NH - OM wherein, R is an alkyl, aryl or alkylaryl group having 6-20 carbon atoms; and M is hydrogen or an alkali metal.
In a second aspect the present invention provides a method for treating a substrate comprising the steps in sequence of preparing a 0.05- 1 % by weight solution of the composition according to claims 1 to 8 in water, rinsing the substrate in the prepared solution, and drying the substrate.
In a third aspect the present invention provides a method for preparing the composition of the invention comprising the steps in sequence of dispersing the anionic surfactant in a mixture of water and non-ionic polymer, mixing the cationic surfactant into the non- ionic polymer and anionic surfactant mixture, adding the chelating agent to the mixture; and optionally adding a perfume.
In a fourth aspect the present invention provides a bottled rinse conditioner agent comprising the composition according to the invention in a 250 ml to 5 L bottle.
For the avoidance of doubt, the improved cleaning upon the subsequent wash benefit is also referred to as next time cleaning benefit.

Detailed description of the invention
The present invention provides a composition for treating a substrate, comprising a surfactant complex selected from cationic and anionic surfactants; a non-ionic polymer and; a chelating agent, selected from hydroxamates of the formula R- CO - NH - OM. The balance of the composition is made up to 100% by weight with water. Surfactant complex
The surfactant complex of the present invention is a detersive surfactant system comprising surfactants selected from cationic and anionic surfactants. The cationic and
anionic surfactants are present in a ratio such that the cationic : anionic surfactant weight ratio is from 1 :1 to 6:1 , preferably from 2:1 to 6:1 .
Cationic surfactants are included in the composition for rendering softness to the fabric. The cationic surfactant used herein may be a quaternary ammonium salt of the general formula: R-|R2R3R4N+ X", wherein
N is nitrogen; R1 is C8-C22 alkyl, alkenyl, alkyl/alkenylamidopropyl, alkoxyalkenylethyl,
alkyl/alkenyl(poly)alkoxyalkyl, C C4 alkyl C8-C2o alkanoate or alkenoate group, or a C2- C4 alkyl bis [C8-C20 (alkanoate or alkenoate)] group.
R2 is Ci-C22 alkyl group, C2-C22 alkenyl group, C8-C22 alkyl/alkenylamidopropyl, alkyl/alkenyl(poly)alkoxyalkyl, alkanoylethyl or alkenoylethyl group or a group of the formula— A— (OA)n— OH , C C4 alkyl C8-C20 alkanoate or alkenoate group, or a C2-C4 alkyl bis [C8-C20 (alkanoate or alkenoate)] group.
R3 and R4 are Ci -C4-alkyl or hydroxyalkyl group, C2-C2i alkenyl group or a group of the formula— A— (OA)n— OH;
A is— C2H4— and/or— C3H6— ;
n is a number from 0 to 20;
O is oxygen;
H is hydrogen; and
X is an anion such as chloride, bromide, iodide, nitrate, sulphate or a methyl or ethyl sulfate. The preferred cationic surfactants of the present invention are esterquats in which partially hardened triethanolamine ester quats are most preferred.
Non-limiting examples of the cationic surfactants that can be used according to the present invention include methyl bis[ethyl (tallowate)]-2-hydroxyethyl ammonium methyl sulphate; methyl bis[ethyl (palmate)]-2-hydroxyethyl ammonium methyl sulphate, ditallow dimethyl ammonium chloride; ditallow dimethyl ammonium methyl sulfate; dihexadecyl dimethyl ammonium chloride; di (hydrogenated tallow alkyl) dimethyl ammonium chloride; dioctadecyl dimethyl ammonium chloride; dieicosyl dimethyl ammonium chloride; didocosyl dimethyl ammonium chloride; di (hydrogenated tallow) dimethyl ammonium methyl sulfate; dihexadecyl diethyl ammonium chloride; di(coconut alkyl) dimethyl ammonium chloride.
Most preferred examples of the cationic surfactants that can used according to the present invention include Methyl bis[ethyl (tallowate)]-2-hydroxyethyl ammonium methyl sulphate, Methyl bis[ethyl (palmate)]-2-hydroxyethyl ammonium methyl sulphate.
Anionic surfactants are included in the composition for primary cleaning action. Any non-soap anionic surfactant known in the art for use in laundry detergents may be used herein. Preferred anionic surfactants are water-soluble salts, particularly alkali metal, ammonium and alkylolammonium salts of organic sulphur reaction products having in their molecular structure an alkyl group containing from about 10 to 20 carbon atoms and a sulphonic acid or sulphuric acid ester group. Non-limiting examples of the anionic surfactants include any of the common anionic surfactants such as linear or modified, e. g., branched, alkylbenzene sulphonates, alkylpoly(ethoxylates), alkyl sulphates, methyl ester sulphonates, or mixtures thereof.
In the composition of the present invention, the surfactant complex may be present in a concentration of 2 -22%, preferably not more than 20%, more preferably not more than 15% but preferably not less than 3% by weight of the total composition.
For the best stability of the compositions, and to obtain compositions that do not phase separate, the concentration of the surfactant complex is preferably between 3- 20 % by weight of the total composition. Without wishing to be bound by a theory, it is thought that the coulombic interaction of the positively charged quaternary ammonium ion of the cationic surfactant and the negative charge on the sulfate/sulfonate group of the anionic surfactant leads to formation of a complex adduct. Non-ionic polymer
The composition according to the invention comprises a non-ionic polymer. Non-ionic polymers typically comprise of hydrophilic and lipophilic parts. To define the hydrophilic to lipophilic balance, the HLB value of a polymer is widely used in the art. The polymer is used to stabilise the composition and aid in the deposition of the composition onto the fabric.
The composition comprises 0.5 - 10% by weight of the non-ionic polymer, preferably at least 1 %, more preferably at least 3% by weight, but typically less than 8% by weight of the composition. For the best stability the concentration is preferably at least 1 %. For the best stability and cleaning performance the polymer is preferably present in a concentration of from 1 to 10% by weight, more preferably from 1 to 8% by weight of the composition. HLB values may be calculated, e.g. by Griffin's method (Griffin WC: "Calculation of HLB Values of Non-Ionic Surfactants," Journal of the Society of Cosmetic Chemists 5 (1954): 259), or Davies' group contribution method (Davies JT: "A quantitative kinetic theory of emulsion type, I. Physical chemistry of the emulsifying agent," Gas/Liquid and Liquid/Liquid Interface. Proceedings of the International Congress of Surface Activity (1957): 426-438); or the group calculation method (HLB= 7+∑(Hydrophilic group numbers)-∑(Lipophilic group numbers)).
For the purpose of the present invention, compositions providing excellent perfume delivery to and extended perfume release from the fabric are obtained when the HLB value is in the range from 12.5 to 18. The best mud cleaning properties are obtained when the HLB value is between 14 and 17, preferably between 15 and 16.
For the best stability of the compositions, and to obtain compositions that do not phase separate, the HLB is preferably between 14 and 17.
The non-ionic polymer of the invention is preferably selected from homopolymers and copolymers of alkylene oxides, including ethylene oxide and propylene oxide and copolymers thereof, polypropylene glycols and polyvinyl alcohols, having an HLB value in the range from 12.5 to 18.
Ethylene oxide/Propylene oxide block co-polymer and polyvinyl alcohols are the most preferred.
To get the best stability and cleaning of the composition, it is preferred that poly vinyl alcohol polymers (PVA), when used, is in a concentration of 1 -10% by weight of the composition and have a degree of hydrolysation of at least 75(%), preferably at least 80%, or even at least 85%, but preferably less than 95%. A degree of hydrolysation between 85-91 %, or even 87-89% is the most preferred. The molecular mass of the PVA is less than 50ku, preferably between 10ku and 50ku, and most preferably in the range of 12ku and 25ku. For the avoidance of doubt, "u" is the SI atomic mass unit, also known as amu, Dalton, D or Da.
Ethylene oxide/Propylene oxide block co-polymers (commercially available as Pluronic, ex BASF) used in the present invention have a molecular mass of less than 50 ku, preferably between 2.5ku and 25ku, and a PPG block of between 5 and 30%, more preferably 10-25%, or even between 15 and 20% by weight of the polymer.
To get the best stability and cleaning of the composition, it is preferred that Ethylene oxide/Propylene oxide block co-polymers, when used, is in a concentration of 2-10% by weight of the composition and is a triblock co-polymer. It is found that when a non-ionic polymer of more than 50 ku is used, the composition phase separates resulting in inferior cleaning, especially of particulate stains.
Chelating agent
To further enhance the next time cleaning benefit and reduce the re-deposition of the stains onto the fabric, the composition further comprises a chelating agent,
The chelating agent of the present invention is selected from hydroxamates of the formula: R- CO - NH - OM
where, R is an alkyl, aryl or alkylaryl group having 6-20 carbon atoms; and
M is hydrogen or an alkali metal.
In the above formula, R is preferably hexyl, octyl, decyl, dodecyl, 2-ethylhexyl, oleyl, eicosyl, phenyl, naphthyl or hexylphenyl; and M is lithium, sodium, potassium, rubidium or caesium.
Without wishing to be bound by theory, it is believed that the hydroxamate deposited onto the fabric acts by binding to the metal ions that are present in the stains thereby preventing the contact of the stains with the fabric and facilitating easy removal and suspension of the metal ions, such as iron ions from the fabric into the wash liquor and thus reducing re-deposition of dirt onto the fabric.
The composition comprises 1-7% by weight of the chelating agent, preferably at least 2%, more preferably at least 3% by weight, but typically not more than 6%, more preferably not more than 5% by weight of the composition.
For the best stability of the compositions, and to obtain compositions that do not phase separate, the concentration of the chelating agent is preferably between 1- 6 % by weight of the total composition. Further optional polymers
For the best cleaning performance upon the subsequent wash, especially for improved cleaning of soils and stains it is preferred that the composition further comprises a further polymer. It is found that the addition of methyl cellulose improves the removal of soils and stains upon the next wash. The most preferred is methyl cellulose having a methoxy substitution of between 27.5-31 .5% by weight of the methyl cellulose and preferably has a degree of substitution (D.S., average number of substituent groups attached to the ring hydroxyls) between 1.5 and 1 .9. It is preferred that a 2% solution of the methyl cellulose in water has a viscosity of between 2000 and 6000 mPa.s (at 20°C, measured in a Brookfield viscometer). The composition preferably comprises between 0.1 and 2% by weight of the composition of the methyl cellulose.
Water
The composition of the present invention is an aqueous composition comprising water. The composition is preferably made upto 100 percent by adding water.
Optional ingredients
The composition typically comprises a perfume, typically between 0.1 and 10% of the total composition, preferably between 0.1 and 5%, or even between 0.3 and 3% of the composition.
The composition may further comprise softening agents as commonly used in fabric softening compositions, antimicrobial agents, silicone oils and co-solvents like 2- phenoxyethanol (commercially available as ex Dow Chemicals as Dowanol EP- trademark) to improve stability and dispersibility.
In addition, the formulation may optionally contain certain non-ionic surfactants. Any type of non-ionic surfactants may be used. In general, the non-ionic surfactants may be chosen from the surfactants described in 'Surface Active Agents' Vol. 1 , by Schwartz & Perry, Interscience 1949, Vol. 2 by Schwartz, Perry &Berch, Interscience 1958, in the current edition of 'McCutcheon's Emulsifiers and Detergents' published by
Mnufacturing Confectioners Company or in Tenside- Taschenbuch', H.Stache, 2nd Edn., Carl Hauser Verlag, 1981.
Process for treating a fabric
In another aspect the invention provides a method for treating a substrate comprising the steps of preparing a 0.05 - 1 % by weight solution of the composition of the invention in water, rinsing the substrate in the prepared solution, and drying the substrate. The solution is preferably 0.1 - 0.5% by weight of the composition in water.
The solution as dosed to a commercially available front load - horizontal axis - washing machine is typically between 25 and 100 ml of the composition into 12-15 L of rinse water. For top load - vertical axis - washing machines the dosage is typically 50-150 ml to 50-60 L of rinse water.
Process for preparing the composition
In another aspect the invention provides a method for preparing the compositions according to the invention comprising the steps in sequence of dispersing the anionic surfactant in a mixture of water and non-ionic polymer, mixing the cationic surfactant into the non-ionic polymer and anionic surfactant mixture in a mixer at 4000 rpm for 5- 10 minutes at 30 °C, adding a chelating agent to the mixture and mixing at 4000 rpm for 5 minutes, and optionally adding a perfume and mixing at 4000 rpm for 2-3 minutes at 30 °C.
Further ingredients according to the invention may be added subsequently.
Product Format
The product is typically packed in a bottle, preferably a plastic bottle at volumes of between 250 ml and 5 L, more preferably between 250 ml and 1.5 L. Common supermarket size bottles are 250 ml, 500 ml, 750ml, 1 L and 1 .5 L. The bottles may optionally have a measuring cup attached, or a measuring scale indicator in the cap, to enable the consumer to dose the right amount into the rinse conditioner compartment of the washing machine.
Also considered in the context of the present invention for the purpose of direct application, such as direct application onto a fabric article or a household surface, is a product format in the form of a bottle with a trigger spray dispenser comprising the composition according to the invention. Trigger spray dispenser bottles typically have a volume of between 250 ml and 1.5 L. Common volumes include 400 ml, 500 ml, 750 ml, and 1 L.
Larger containers for industrial scale use are also included the scope of this invention.

Preparing the compositions
First, the anionic surfactant was dispersed in a water and non-ionic polymer mixture. To this mixture, cationic surfactant was added and mixed well in a mixer at 4000 rpm for 5-10 minutes at 30 °C. Following which, a chelating agent was added to the mixture and mixed at 4000 rpm for 5 minutes, and perfume was added and mixed at 4000 rpm for 2-3 minutes at 30 °C. Further ingredients as used in some of the examples were added subsequently.
Fabric treatment protocol
All the treatment processes in the examples were carried out in a 5 kg front loader washing machine (IFB, MODEL: SENATOR DX, 5 kg) with 6°fH water. 10 of each cotton, poly-cotton and polyester 10x10 cm2 swatches were used for treatment. 3.5 kg of fabrics which comprised of a mix of cotton, poly-cotton and polyester shirts were used as ballast material. The fabric swatches were stapled into one of the ballast shirts. 30 grams of Surf Excel Matic - Front Load (ex Hindustan Unilever Ltd, India) was used for the main-wash and it was dispensed through the detergent compartment of the
machine. In a typical process, 35 mL of the test formulation as described in the examples, was used for fabric surface treatment and was dispensed through the fabric conditioner compartment of the machine during the third (=final) rinse. After the completion of the full cycle (comprising of wash step, and 3 rinse steps and centrifuging), the swatches were removed and then dried in a drier and ironed.
Staining Protocol
Red mud soiling: To 1 L de-ionized water 5 g of red mud (sieved, < 150 microns) was added and sonicated in a sonication bath for 2 hrs. 0.2 ml of this slurry was dropped onto the fabric which was placed at an inclined plane of 45°. The fabrics were allowed to dry over- night.
Tea stain soiling: Two tea bags were dipped in 150ml hot milk to make tea. 0.2 ml of this tea was dropped onto the fabric which was placed at an inclined plane of 45°. The fabrics were allowed to dry over-night.
Dirty Motor oil (DMO) stain soiling: 50 ml of motor oil was mixed with 50 ml of engine oil to obtain the stain. 0.2 ml of the stain was dropped onto the fabric which was placed at an inclined plane of 45°. The fabrics were allowed to dry over-night.
Washing Protocol
The soiled 10x10 cm2 swatches were stapled onto one of the ballast shirts (as described in the fabric treatment protocol). Total wash load was 3.5kg comprising of the soiled swatches and the ballast shirts. Washing was done with 30 grams Surf Excel Matic Front Load (ex Hindustan Unilever Ltd, India) at 6°fH. Cotton, poly-cotton and polyester swatches, both treated and untreated, were used for each study. A typical wash cycle comprised of wash and two rinses along with spin. After washing was completed, the swatches were removed and then dried in the drier. Evaluation of fabrics
The extent of stain removal was compared against the control (untreated) fabrics on a one to one basis for each stain type. A score "+" was given in cases where the stains on the treated fabrics appeared lighter than that on the untreated fabrics. Similarly, a
score "-" was given in cases where the stains on the treated fabrics appeared darker than that on the untreated fabrics. In all the cases, the evaluation was done by trained panellists. Reflectance measurement:
The reflectance of the fabric was measured at AR460 (values at 460 nanometer, UV excluded) using a Macbeth 7000 color eye reflectometer. A SAV aperture and SAV lens were used for the measurement. Reflectance measured of the fabrics (control and experimental) were recorded each time before and after washing. The extent of stain removal for any given set was evaluated from the difference in their reflectance values before and after washing, as shown below:
AR(Control)= Rfinai (Control)-
(Control);
where, Control refers to untreated fabrics
AR(Experimental)= Rfinai (experimental)- Rinitiai(experimental)
where, Experimental refers to fabrics treated with the said formulations.
Extent of stain removal (W.r.t untreated) A(AR)= AR(Experimental)- AR(Control).
For each set of experiments, three replicates of each fabric type were used. The average A(AR) values were calculated and compared. The higher the average A(AR) values, the better is the cleaning efficacy.
Evaluation of Perfume Performance
50X50 cm2 polyester swatches were used for the perfume evaluation study. 5 swatches were treated with each of the test formulation, as described in the examples, in a manner already described. 35 mL of test formulation was used for treatment. As a
®
control, 40g Comfort (Blue variant, India) was used. After 2 hours of treatment and drying, the perfume impact of the treated swatches was compared against the control (in this case Comfort treated) on a one to one basis for each set. A score "+" was given in cases where the perfume impact on the treated fabrics appeared greater than that on the control fabrics. Similarly, a score "-" was given in cases where the perfume
impact on the treated fabrics appeared lesser than that on the control fabrics. In all the cases, the evaluation was done by trained persons.
Evaluation of Softness Benefits
100X100 cm2 terry-towel swatches were used for the softness evaluation study. 5 such swatches were treated with each of the test formulation, as described in the examples, in a manner already described. 35ml of test formulation was used for treatment. After 2 hours of treatment and drying, the softness impact of the treated swatches was
®
