DESCRIPTION

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 textile materials; particularly to make the substrate stain repellent and easier to clean with subsequent washing.

The invention has been developed primarily for use in textile materials, and will be described hereinafter with reference to these applications.

Background of the invention

Generally the textile materials are cleaned with detergents. Conventional detergent compositions include surfactants and detergency builders. Surfactants clean textile materials. Some detergent compositions also contain soda ash to enhance the cleaning action. Many detergent compositions also include specialty polymers that help release stains. Such polymers are called dirt release polymers (SRP). Some detergent compositions also include additives that reduce the redeposition of dirt that is released in the wash waters. Such additives are called anti-redeposition agents (ARD).

Textile materials tend to stain during use. The spots are generally either oily or watery. Common sources of water stains include tea, coffee, beverages and inks. Common sources of oily spots include pickles, sauces and ketchups, motor oil and grease. People prefer to dress in clothes that have less stains. This is particularly applicable to white textile materials, such as white shirts. People also prefer that bathroom surfaces, kitchen and window surfaces be free of stains.

One of the ways to prevent textile materials and hard surfaces from staining is to treat them with compositions that form a film on the surface of the textile material or the hard surface. This film prevents, or at least reduces, the adhesion of spots. The film also allows easy removal of stains during washing, and it can be said that it forms a sacrificial layer, as disclosed in the application WO 2009/077255.

Another way to provide easier cleaning with the next wash is to reduce the ability of the textile material to get dirty or stained. Normally metal salts are generally present in such compositions. The surfaces get stained when the spots spread over them. In such cases, the stain moistens the surface. When a spot moistens a surface, the contact angle between the spot and the surface is very low, generally less than 10 (°). When a composition for surface treatment forms a film, the film increases the contact angle. In other words, this movie does not allow the stain to moisten the surface. Generally, a contact angle of water in the range of 90 (°) to 170 (°) is considered good for repelling aqueous stains. On the other hand, oil contact angles greater than 60 are considered good to repel oily spots. Such treated surfaces may be called superhydrophobes or superoleophobes. Compositions for providing such stain repellency to textile materials are described in WO 2010/069731.

The contact angle is the angle at which a liquid / vapor contact surface (or two immiscible liquids) meets a solid surface. The contact angle is specific to any given system and is determined by the interactions between the two contact surfaces. Most often, the concept is illustrated with a liquid droplet placed on a flat horizontal solid surface. The shape of the droplet is determined by the Young-Laplace equation. One of the ways to measure the contact angle is to use a contact angle goniometer in a sessile drop of the liquid. This method is used to estimate the wetting properties of a region located on a solid surface. The angle between the base of the drop and the tangent at the limit of the drop is the contact angle.

Compositions for the treatment of textile materials have been disclosed in the applications of India being processed together with this unpublished WO 2011/134755 and WO 2011/134756 (both of Unilever). WO 2011/134756 discloses liquid stain repellent compositions and a method for their use. The compositions help make the substrates, particularly textile materials, repellent to hydrophilic stains. Compositions include 25 to 50% by weight of soap, 10 to 30% by weight of a complex of zinc and triethanolamine, 30 to 65% by weight of trivalent metal ion and / or tetravalent metal ion, and a solvent that has a lower alcohol and water in a ratio of 99: 1 to 85:15.

Ideally, such compositions are dosed in the final rinse of the machine wash cycle, together with or instead

of a conditioner of textile materials.

In US 4,555,349, textile material conditioners comprising metal salt and soap electrolytes have been disclosed, however, they have not been found to provide any stain repellency or improvement in cleaning benefits in washing later. Similar compositions are disclosed in US 4,417,995, which discloses a fabric softener composition comprising aluminum hydrochloride (also known as poly (aluminum chloride)) and Pristerene (a tallow fatty acid), but such compositions do not provide improvement in cleaning in subsequent washing or improvement in stain repellency. Furthermore, US 4,555,349 and US 4,417,995 do not provide an improvement in the supply of perfume to the textile material.

GB 552447 discloses a permanent coating for impermeable and imputrescible materials. Similarly, GB 662945 discloses a composition for the treatment of textile materials that serves as an ironing aid and gives the textile material a permanent, protective, stain resistant, water repellent and starch finish. In addition, GB 662945 discloses polymer concentrations of less than 0.3%. However, when it comes to textile materials, consumers prefer removable coatings to permanent ones. Therefore, it is still desirable to have compositions that confer an improvement in stain repellency and cleaning benefits the next time through a textile material conditioner.

WO 01/07551 discloses the use of polyvinyl alcohols (soil release polymers) as detergent additives in main wash detergent compositions. However, the composition disclosed in this document does not provide a cleaning benefit next time through a conditioner of textile materials.

US 4136038 relates to conditioning compositions of textile materials comprising a polymer for dirt release. However, the composition disclosed in this document does not provide a cleaning benefit next time. Therefore, a cleaning benefit is still desired next time through a textile material conditioner.

It is an object of the present invention to provide stain repellency to a textile material.

It is a further object of the present invention to provide an improvement in cleaning with subsequent washing.

It is yet another object of the invention to provide a stable composition that does not separate into phases.

It is still another object of the invention to provide a composition that provides an improvement in the supply of perfume to the textile material.

It is still another object of the invention to provide a composition that provides an improvement in the release of perfume from the textile material.

It is still another object of the invention to provide a composition that provides softness to the textile material.

Surprisingly, it has been found that an improvement in the perfume supply is obtained in compositions comprising a fatty acid, a water-soluble aluminum salt and a non-ionic polymer. The improvement in stain repellency is obtained when the polymer's HLB is between 12 and 18.

Summary of the invention

Accordingly, the present invention provides a composition for treating a substrate, said composition comprising 2-25% by weight of a C8-C24 fatty acid, 2.5-40% by weight of a water soluble aluminum salt, 0.01 -2.0% by weight of an alkalinity source; 0.3-10% by weight of a non-ionic polymer having an HLB value of 10 to 20, perfume and water; and in which the pH of the composition is between 1 and 6 and in which 5 to 50% by weight of the total fatty acid is neutralized by the alkalinity source.

In a second aspect, the present invention provides a method for treating a substrate comprising the steps of preparing a 0.05-1% solution by weight of the composition according to the invention in water, clearing an article of textile material in the solution and dry the article of textile material.

In a third aspect, the present invention provides a method for preparing the composition of the invention comprising the steps in sequence of partially neutralizing a fatty acid with the alkali source at a temperature above the melting point of the fatty acid, mixing the polymer in the partially neutralized fatty acid mixture, add the aluminum salt to the mixture, homogenize the mixture and allow the composition to cool to room temperature; and optionally add a perfume.

In a fourth aspect, the present invention provides a bottled rinse conditioning agent comprising the composition according to the invention in a 250 ml bottle at 5 l.

For the avoidance of doubt, improved cleaning after the benefit of subsequent washing is also called cleaning benefit next time, while the composition as applied to the textile material is also called the sacrificial layer. The benefit of reduced uptake of stains or dirt on or in a textile material is also called stain repellent, regardless of whether it refers to a specific stain or dirt in general.

These and other aspects, features and advantages will be apparent to those skilled in the art from a reading of the following detailed description and the appended claims. For the avoidance of doubt, any feature of one aspect of the present invention can be used in any other aspect of the invention. The term "comprising" is intended to mean "including" but not necessarily "consisting of" or "composed of." In other words, it is not necessary for the stages or options listed to be exhaustive. It is indicated that the examples provided in the description below are intended to clarify the invention and are not intended to limit the invention to these examples per se. Similarly, all percentages are weight / weight percentages unless otherwise indicated.

It is understood that the numerical intervals expressed in the format "from x to y" include x and y. When multiple preferred intervals are described for a specific characteristic in the "from x to y" format, it is understood that all intervals combining the different endpoints are also contemplated.

Detailed description of the invention

The present invention provides a composition for treating a substrate, comprising a C8-C24 fatty acid, a water-soluble aluminum salt, a source of alkalinity; a non-ionic polymer and perfume. The composition preferably comprises additional optional components. The rest of the composition is made up to 100% by weight with water. The pH of the composition is between 1 and 6.

Fatty acid

The composition comprises a fatty acid comprising a carbon chain length of from 8 to 24 carbon atoms, hereinafter referred to as C8-C24 fatty acid. The composition preferably comprises a fatty acid having a carbon chain length of at least 10 carbon atoms, but preferably not more than 20, more preferably not more than 18, still more preferably not more than 16 carbon atoms or even not more than 14 carbon atoms. Combinations of different fatty acids from a cost perspective are preferred, since commercially available fatty acids typically comprise a mixture of different fatty acids with similar chain lengths.

The fatty acid may or may not have one or more double bonds or triple carbon-carbon bonds. The iodine index, which is indicative of the degree of unsaturation, is preferably less than 20, more preferably less than 10 and most preferably less than 5. Particularly preferred is fatty acid that does not have a double bond or triple carbon-carbon bond. .

Fatty acids are insoluble in water. Non-limiting examples of water insoluble fatty acids that can be used according to the present invention include lauric acid, caprylic acid, myristic acid, stearic acid, oleic acid and palmitic acid.

The composition comprises 2-25% by weight of the fatty acid, preferably at least 5% or even at least 10% by weight, but usually less than 22% by weight of the composition.

Alkalinity source

The composition comprises a source of alkalinity. The purpose of the alkalinity source is to partially neutralize the fatty acid. Preferably 5-50% by weight of the total fatty acid is neutralized by the alkalinity source, more preferably at least 10%, more preferably at least 12% or even at least 15% by weight, but usually not more than 40%, more preferably no more than 30% by weight of the total fatty acid is neutralized.

The source of alkalinity is preferably a hydroxide salt, more preferably an alkali metal hydroxide, in which sodium and potassium hydroxides are the most common. Sodium hydroxide is the most preferred alkalinity source.

To neutralize the fatty acid to a degree of 5-50% by weight of the total fatty acid, the composition comprises 0.05-0.5 mol of a hydroxide salt per mol of the fatty acid.

Therefore, the composition comprises 0.01-2.0% by weight of an alkalinity source, preferably at least 0.02%, more preferably at least 0.05%, still more preferably at least 0, 1% by weight, but usually not more than 1.5%, more preferably not more than 1.2% by weight of the composition.

Aluminum salt

The aluminum salt is preferably a water soluble aluminum salt, including aluminum nitrate, aluminum sulfate and aluminum chloride. For the avoidance of doubt, the aluminum compounds of the invention include poly (aluminum salts), including poly (aluminum chloride) and poly (aluminum sulfate). Poly (aluminum chloride) is the most preferred.

The poly (aluminum chloride) (PAC) can be defined as a non-stoichiometric aluminum hydroxychloride oligomer having the general formula [AlnCl (3n-m) (OH) m] where the value of m is preferably in the range of 5 to 24 and preferably in the range of 2 to 12.

Water insoluble aluminum compounds such as clays, alumina and aluminum hydroxide are excluded from the scope of the present invention.

The best results are obtained when a 1% solution of the aluminum salt according to the invention in water of 20 ° C provides a pH between 1 and 6, more preferably between 2 and 5.

The composition comprises 2.5-40% by weight of the water soluble aluminum salt, preferably at least 5%, more preferably at least 10% by weight, but usually not more than 30%, more preferably not more 25% by weight of the composition.

Without wishing to restrict itself to a theory, it is believed that the aluminum salt and fatty acid form an aluminum soap that is deposited on the fibers of the textile material, thereby providing hydrophobicity.

Additional polyvalent metal ion

Additional improved results can be obtained when the composition comprises an additional polyvalent metal ion. From the perspective of the cost of the composition, several polyvalent metal ions are also less expensive than aluminum, and therefore more preferred. The polyvalent metal salt is ideally soluble in water.

Metal salts provide additional ionic strength to the medium that aids in the deposition of active agents on the surface. Therefore, polyvalent metal salts are more preferred than monovalent metal salts. Polyvalent metal salts are also more hydrolyzable than monovalent metal salts and thus tend to aid in the deposition of active agents in addition to flocculation and weak agglomeration of active agents on the surface.

Preferred polyvalent metal ions are selected from alkaline earth metal ions, titanium and zinc ions. More preferably, metal salts include calcium, zinc, magnesium, barium, titanium, more preferably calcium, zinc, magnesium or iron is chosen. These metal salts can be used in combination with PAC in the composition. Chromium is not preferred for domestic use since it is toxic. The corresponding anions of the metal salts may be chloride, nitrate, sulfate and acetate, or other water soluble anions. Chloride, nitrate, sulfate and acetate are the most preferred.

The polyvalent metal salt is preferably present in the composition in a concentration of between 5 and 30% by weight, more preferably 5-25% by weight, still more preferably 5-20% by weight, or even 515 % by weight of the composition.

When a polyvalent metal salt is present, the combined amount of the water soluble aluminum salt and the polyvalent metal salt together is 7.5-40% by weight, preferably at least 10% by weight, but usually not more than 30%, more preferably not more than 25% by weight of the composition.

When both aluminum (Al) and the additional polyvalent metal (M) are present in the composition, the best results are obtained when the molar ratio of Al to M is between 0.2 and 2.5 for a good supply of fragrance. The best hydrophobicity and stability results are obtained between 0.5 and 2.5. The best cleaning results are obtained at a molar ratio of between 0.2 and 1, preferably between 0.5 and 1.

Reason for fatty acid with respect to metal ion

The ratio of fatty acid to metal ion determines the deposition of perfume, the hydrophobicity of the textile material and the cleaning efficiency.

Fatty acid with respect to aluminum alone

The ratio of fatty acid to aluminum salt (based on weight) is preferably between 0.2 and 5 for a good deposition and supply of perfume, preferably between 0.4 and 2 or even between 0.6 and 1 , 5 for hydrophobicity and improved stain repellency.

The compositions are usually separated in phases at fatty acid ratios with respect to aluminum salt above 1.5 (based on weight). However, 2-phase systems that need to be shaken before use are also acceptable to the consumer.

For the best stain-repellent properties, the ratio of fatty acid to aluminum salt is preferably between 0.6 and 1.5, or even more preferably between 0.8 and 1.2 based on weight.

Reason for fatty acid with respect to total metal ion (aluminum + additional polyvalent metal)

The ratio of fatty acid to metal ion (on a molar basis) is preferably between 0.2 and 2 for a good deposition and supply of perfume, preferably between 0.5 and 1.2 for a hydrophobicity and repellency of Improved stains

The compositions are usually separated in phases or solidified at fatty acid ratios with respect to metal ion (on a molar basis) above 1.2.

For the best stain repellent properties, the ratio of fatty acid to metal ion is preferably between 0.6 and 1.5, or even more preferably between 0.8 and 1.2 on a molar basis.

Polymer

The composition according to the invention comprises a non-ionic polymer. Non-ionic polymers normally comprise the 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 stabilize the composition and aid in the deposition of the composition on the textile material.

The HLB values can be calculated, for example by the Griffin method (Griffin WC: "Calculation of HLB Values of Non-Ionic Surfactants", Journal of the Society of Cosmetic Chemists 5 (1954): 259), or the contribution method of Davies groups (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 method of calculating groups (HLB = 7 + X (numbers of hydrophilic groups) -X (numbers of lipophilic groups)).

For the purpose of the present invention, compositions are obtained which provide an excellent perfume supply a and a prolonged perfume release from a textile material when the HLB value is in the range of from 10 to 20.

The best stain repellent properties are obtained when the HLB value is between 10 and 18, preferably between 12 and 18, or even between 15 and 17.

For the best stability of the compositions, and to obtain compositions that do not separate into phases, the HLB is preferably between 12 and 18.

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 and polyvinyl alcohols, which have a HLB value in the range of from 12 to 20.

Block copolymer of ethylene oxide / propylene oxide and polyvinyl alcohols are most preferred.

In order to achieve the best stability of the composition, it is preferred that polyvinyl alcohol (PVA) polymers, when used, have a degree of hydrolyzing of at least 75 (%), preferably at least 80% or even at least 85%, but preferably less than 95%. A degree of hydrolyzing between 85-91%, or even 87-89% is most preferred. The molecular mass of the PVA is preferably between 10,000 u and 200,000 u.

Especially preferred are ethylene oxide / propylene oxide block copolymers (commercially available as Pluronic, from BASF), and preferably have a molecular mass of between 2500 and 25000 u (in which u is the SI atomic mass unit) , and a PPG block of between 5 and 30%, more preferably 10-25%, or even between 15 and 20% by weight of the polymer.

Optional additional components for oily dirt removal

For the best cleaning performance with subsequent washing, especially for an improved cleaning of dirt and oily stains, it is preferred that the composition also comprises an additional polymer or non-ionic surfactant.

Cellulose polymers

It is found that the addition of a lower alkyl cellulose, preferably methyl cellulose, improves the removal of oily dirt after the next wash. It is preferred that a 2% solution of the alkylcellulose in water has a viscosity between 2000 and 6000 mPa.s (at 20 ° C, measured in a Brookfield viscometer). The composition preferably comprises between 0.1 and 2.5% by weight of the alkyl cellulose composition.

Similar results are found with dirt release polymers, such as Rhodia's Repel-O-Tex range (trade mark) ie SF2, PF94, Crystal, notably Repel-O-Tex SF2. The composition preferably comprises between 0.1 and 2.5% by weight of the dirt release polymer.

Similar results can be obtained with sodium carboxymethylcellulose having a molecular mass of 40-200 ku, poly (acrylic acid) having a molecular mass of 2 k-100 ku and poly (ethylene oxide) having a molecular mass of 10 k -100 ku.

The best results are obtained when both the Repel-O-Tex polymer and the alkyl cellulose are included in the composition.

Larger containers for industrial scale use are also included within the scope of this invention.

Examples

The invention is now illustrated by means of the following non-limiting examples.

Preparation of the compositions

First, a fatty acid with alkali solution was partially neutralized at a temperature of 70 ° C. Then, polyvinyl alcohol was mixed in the partially neutralized fatty acid. After that, PAC was added to the previous mixture. After the complete addition of PAC, the mixture was homogenized for 5 min and allowed to cool to room temperature (25 ° C) and perfume was added to the cooled mixture and mixed well. Additional components were subsequently added as used in some of the examples.

Textile treatment protocol

All the treatment processes in the examples were carried out in a 5 kg front loading washing machine (manufactured by IFB, 5 kg) with 62fH water. 10 10x10 cm samples of cotton, polyalgodon and polyester each were used for the treatment. 3.5 kg of textile materials were used comprising a mixture of cotton, polyalgodon (60:40) and polyester shirts as ballast material. Samples of textile material were stapled on one of the ballast shirts. 30 grams of Surf Excel Matic - Front Load (from Hindustan Unilever Ltd, India) were used for the main wash and dispensed through the detergent compartment of the washing machine. In a typical process, 40 g of the test formulation was used as described in the examples for the surface treatment of textile materials and dispensed through the textile material conditioner compartment of the washing machine during the third rinse (= final). After completion of the complete cycle (comprising washing and 3 rinsing with centrifugation), the samples were removed and then dried in a dryer and ironed.

Evaluation of the hydrophobicity of textile materials

Wash protocol

Dirty 10x10 cm samples were stapled onto one of the ballast shirts (as described in the textile materials treatment protocol). The total wash load was 3.5 kg, which included dirty samples and ballast shirts. Washing was done with 30 grams of Surf Excel Matic Front Load (from Hindustan Unilever Ltd, India) at 6 ° fH. Samples of cotton, polyalgodon and polyester, both treated and untreated, were used for each study. A typical wash cycle included washing and two rinses along with centrifugation. After the washing was completed, the samples were removed and then dried in the dryer.

The degree of stain removal compared to control (untreated) textile materials on a one-to-one basis for each type of stains was compared. A “+” score was given in cases where the stains on the treated textile materials seemed lighter than on the untreated textile materials. Similarly, a "-" score was given in cases where the stains on the treated textile materials appeared darker than on the untreated textile materials. In all cases, the evaluation was carried out by a trained person.

Perfume performance evaluation

50x50 cm polyester samples were used for the perfume evaluation study. Five samples were treated with each of the test formulations, as described in the examples, in a manner already described. 40 g of test formulation were used for the treatment. As a control, 40 g of Comfort® were used (market-lot sample No. B.876, Blue variant, India). After 2 hours of treatment and drying, the perfume impact of the treated samples was compared to the control (in this case treated with Comfort) on a one-to-one basis for each set. A “+” score was given in cases where the impact of perfume on treated textile materials seemed greater than on control textile materials. Similarly, a “-” score was given in cases where the impact of perfume on treated textile materials seemed less than on control textile materials. In all cases, the evaluation was carried out by trained people.
