Abstract

Cosmetic treatment of oily skin comprises topical application of a composition comprising a interpenetrated polymer network of polyurethane polymer and acrylic polymer, in a medium, in the form of aqueous dispersion of solid particles, on the skin.

Description

The present invention relates to the cosmetic use of a synthetic polyurethane / acrylic interpenetrating polymer network in the form of an aqueous dispersion of solid particles, in a composition suitable for topical application to the skin, as an agent. mattifying.

The invention also relates to a process for the cosmetic treatment of oily skin, comprising the topical application to the skin of a composition containing, in a physiologically acceptable medium, a synthetic polymer of the interpenetrating polymer network (IPN) type polyurethane / acrylic in the form of an aqueous dispersion of solid particles.

The shine of the skin, often related to a high secretion of sebum, is a problem affecting more particularly adolescents but which can also manifest itself in adulthood under the effect in particular of a hyperproduction of androgens. It can also be related to sweat resulting from physical activity or weather conditions. However, a shiny skin is considered unsightly, especially since it often results in less good hold makeup that tends to degrade visually during the day.

In order to absorb sebum and excess oil from the composition not absorbed by the skin, use is conventionally made of powders of natural or synthetic origin, among which mention may be made in particular of fillers such as talc, starch, mica, silica, nylon powders, polyethylene powders, poly-beta-alanine, poly (meth) acrylate powders. This type of fillers has the disadvantage of giving the skin a powdery appearance, not natural, which can even accentuate skin defects. In addition, the compositions containing them are generally drying in the long term and their effect is not very durable over time.

In addition, it has been proposed by the Applicant to use, as matting agents, vinylpyrrolidone / 1-triacontene copolymers (FR-2,820,972) or particles of melamine-formaldehyde or urea-formaldehyde resin (FR-2,792). 642), acrylic styrene (FR-2 801 215) or polytetrafluoroethylene (FR-2 820 977) or colloidal dispersions of inorganic particles, in particular silica, which can be prepared by a sol-gel process ( 0 682 939).

Although these matting agents have interesting properties, there remains the need for matting agents.

The Applicant has now discovered that the use of a synthetic polymer interpenetrating network type network (said IPN) in the form of aqueous dispersion of particles, used to formulate products for oily skin having a good matting power.

Such a polymer is known from Application FR-A-2843025 for treating skin wrinkles by its tightening effect. However, it is not suggested in this document that such polymers can have an instant matifying effect, that is to say, to impart a dull appearance to the skin upon application, and that they can therefore find an interest. precisely in the care of oily skin.

However, the Applicant has demonstrated that these particular polymers have the aforementioned matifying properties.

The subject of the present invention is therefore a process for the cosmetic treatment of oily skin, comprising the topical application to the skin, in particular oily skin, of a composition comprising, in a physiologically acceptable medium, a polymer of the polymer network type. interpenetrating (said IPN) polyurethane / acrylic in the form of particles in aqueous dispersion.

By "cosmetic treatment of oily skin" in the sense of the present invention is meant the topical application of skincare products, intended to instantly reduce the brightness of the skin.

The invention also relates to the cosmetic use of a synthetic polyurethane / acrylic interpenetrating polymer network in the form of an aqueous dispersion of particles, in a composition suitable for topical application to the skin, as a matting agent.

By "matting agent" in the sense of the present invention is meant a raw material capable of instantly reducing (from the application) the brightness of the skin.

The composition according to the invention is suitable for topical application to the skin and therefore generally comprises a physiologically acceptable medium, that is to say compatible with the skin and / or its integuments.

For the purposes of the present invention, the term "interpenetrating polymer network" is intended to mean a mixture of two entangled polymers obtained by simultaneous polymerization and / or crosslinking of two types of monomer, the mixture obtained having a single glass transition temperature range.

A particularly preferred IPN is in the form of an aqueous dispersion of particles having a number average size ranging from 50 nm to 100 nm.

The IPN preferably has a glass transition temperature range (Tg) ranging from about 50 ° C to + 130 ° C, and preferably from 45 ° C to + 130 ° C. The Tg is measured in particular by scanning differential scanning calorimetry (DSC) using the device DSC 7 from Perkin Elmer, by preconditioning the polymer sample in a climatic chamber for 48 h at 25 ° C. 50% relative humidity, in an aluminum cup.

The measurement is carried out under nitrogen flushing, with a first heating ranging from -45 ° C. to + 140 ° C. at a rate of 10 ° C./min and a second heating ranging from -45 ° C. to + 230 ° C.

IPNs are described in the publication Solvent-free urethane-acrylic hybrid polymers for coating; E. Galgoci et al., JCT Coatings Tech, 2 (13), 28-36 (February 2005), as well as in US Pat. Nos. 4,64,4030 and 5173526. Advantageously, the interpenetrating polyurethane / acrylic polymer network can be prepared according to the method. described in US 5173526. This process comprises the following steps: (a) forming an isocyanate-terminated polyurethane prepolymer comprising water-dispersible carboxylic groups; (b) adding to the prepolymer a vinyl monomer mixture containing an ethylenically unsaturated monomer; (c) adding a tertiary amine to the prepolymer / vinyl monomer mixture; (d) dispersing the prepolymer / vinyl monomer mixture in water; (e) adding a free radical initiator (oil soluble) and a chain extender to the aqueous dispersion; and (f) polymerizing the vinyl monomers and completing the chain extension of the prepolymer by heating the aqueous dispersion. The isocyanate-terminated polyurethane prepolymer can be obtained by reacting organic monomer containing at least two active hydrogen atoms per molecule, especially a diol and preferably a polyester polyol, with an excess of diisocyanate monomer.

Preferably, the polyurethane prepolymer comprises unreacted carboxylic acid groups which are neutralized as tertiary amine salt after prepolymer formation and addition of the vinyl monomers, but prior to formation of the aqueous dispersion. The polyisocyanates used for the manufacture of the prepolymer can be aliphatic, cycloaliphatic, or aromatic. As examples of polyisocyanates, mention may be made of ethylene diisocyanate, lel, 6-hexamethylene diisocyanate, isophorone diisocyanate, cyclohexane-1,4-diisocyanate, 4,4'-dicyclohexylmethane diisocyanate and 1,4-phenylene diisocyanate. 2,4-toluene diisocyanate, 2,6-toluene diisocyanate, 4,4'-diphenylmethane diisocyanate, 2,4'-diphenylmethane diisocyanate, 1,5-naphthylene diisocyanate, and mixtures thereof. Polymeric polyols having a molecular weight ranging from 500 to 6000, preferably from 700 to 3000, which may be used for the preparation of the prepolymer, may be chosen from diols and triols or mixtures thereof. The polyols may be chosen in particular from polyesters, polyesteramides, polyethers, polythioethers, polycarbonates and polyacetals. The polyester polyols may be selected from hydroxyl-terminated reaction products of polyhydric alcohols such as ethylene glycol, propylene glycol, diethylene glycol, neopentyl glycol, 1,4-butanediol, furan dimethanol, cyclohexane, and the like. dimethanol, glycerol, trimethylolpropane, pentaerythritol, or mixtures thereof with polycarboxylic acids, in particular dicarboxylic acids or their ester form, such as succinic acid, glutaric acid, adipic acid or their methyl ester , phthalic anhydride or dimethyl terephthalate. It is also possible to use polyesters obtained by polymerization of lactones, such as caprolactone, and of polyol. The polyesteramides can be obtained using amino alcohols such as ethanolamine in the polyesterification mixture. The polyether polyols which may be used include the products obtained by cyclic oxide polymerization, for example ethylene oxide, propylene oxide, tetrahydrofuran, or by addition of these cyclic oxides to polyfunctional initiators such as water, ethylene glycol, propylene glycol, diethylene glycol, cyclohexane dimethanol, glycerol, trimethylol propane, pentaerythritol, Bisphenol A. The polyethers may also be chosen from polyoxypropylene diols and triols, diols and triols. poly (oxyethylene-oxypropylene) obtained by simultaneous or sequential addition of propylene oxide and ethylene oxide with the appropriate initiators, and polytetramethylene glycol ethers obtained by polymerization of tetrahydrofuran. The polythioether polyols may be chosen from products obtained by condensation of thiodiglycol, either alone or with other glycols, dicarboxylic acids, formaldehyde, aminoalcohols or amino carboxylic acids. The polycarbonate polyols may be chosen from the reaction products of diols such as 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, diethylene glycol or tetraethylene glycol with diaryl carbonates, such as diphenyl carbonate, or with phosgene. The polyacetal polyols may be selected from the reaction products of glycols such as diethylene glycol, triethylene glycol or hexanediol with formaldehyde. The acid group-containing reactive isocyanate group compounds which may be used in the preparation of water-dispersible anionic prepolymers include diols and triols containing carboxylic acid groups, for example those of the formula (I) RC (CH 2 OH) 2 COOH (I) wherein R is hydrogen or a C1-C10 alkyl group. The carboxylic group diol is preferably 2,2-dimethylolpropionic acid. The carboxylic group diol or triol may be incorporated into a polyester by reaction with a dicarboxylic acid before being introduced into the prepolymer. Acidic compounds are for example aminocarboxylic acids, for example lysine, cystine, 3,5-diaminobenzoic acid. The water-dispersible anionic isocyanate-terminated polyurethane prepolymer can be conventionally prepared by reacting a stoichiometric excess of an organic polyisocyanate with a polymeric polyol and any other necessary compound reacting with an isocyanate under anhydrous conditions at a temperature between 30 and 130 ° C until the reaction between the isocyanate groups and the hydroxyl groups is complete.

The polyisocyanate and the active hydrogen-containing compounds are advantageously used so that the ratio of the number of isocyanate groups to the number of hydroxyl groups ranges from 1.1 / 1 to 6/1, preferably 1.5 / 1. to 3/1. It is possible to use a well known tin catalyst to assist in the formation of the prepolymer. A mixture of water-dispersible polyurethane prepolymer containing carboxylic groups and the vinyl monomer is obtained by simply adding the vinyl monomer composition to the prepolymer. The vinyl monomer composition must contain at least one ethylenically initiated monomer. The vinyl monomers which may be added to the prepolymer may be ethylenically unsaturated hydrocarbon monomers, ethylenically unsaturated esters, ethylenically unsaturated ethers, in particular (meth) acrylic acid esters, vinyl alcohol esters, styrene. It may especially be mentioned butadiene, isoprene, styrene, alkyl (meth) acrylates having a C1-C6 alkyl group, alkyl maleates having a C1-C6 alkyl group, vinyl acetate vinyl butyrate, acrylonitrile, vinylmethyl ether, vinylpropyl ether, vinylbutyl ether, vinyl chloride, vinylidene chloride. The unsaturated polyethylenic monomers may be chosen from butadiene, isoprene, allyl methacrylate, diesters of acrylic acid and of C2-C6 diols, such as butylene diacrylate and hexylene diacrylate, divinyl benzene, divinyl ether, divinyl sulfide, trimethylolpropane triacrylate. Advantageously, the vinyl monomer is methyl methacrylate. Before dispersing the prepolymer / vinyl monomer mixture in water, a tertiary amine is added to the mixture in an amount sufficient to render the prepolymer dispersible in water, i.e., in an amount sufficient to neutralize the groups carboxylic. For example, the amine can be added in an amount ranging from 65 to 100% amine equivalent per carboxylic equivalent equivalent. The tertiary amines that can be used are relatively volatile so that they are evaporated from the film after the filming. There may be mentioned, for example, amines of formula R-N (R 1) (R 2) in which R, R 1 and R 2 independently represent a C 1 -C 4 alkyl or hydroxyalkyl group. For example, triethylamine, dimethylethanolamine, methyldiethanolamine and methyldiethylamine may be mentioned. It is important that the tertiary amine be added to the prepolymer / monomer mixture before this mixture is dispersed in water to ensure compatibility of the organic and aqueous phases in the resulting dispersion. The prepolymer / vinyl monomer mixture can be dispersed in water using known technologies. Preferably, the mixture is added to the water with stirring, or the water can be poured into the mixture. The chain extender containing the active hydrogen which reacts with the prepolymer may be a polyol, an amino alcohol, ammonia, a primary or secondary amine, and more particularly a diamine. Mention may be made, for example, of ethylenediamine, diethylene triamine, triethylene tetramine, propylene diamine, butylene diamine, hexamethylenediamine, cyclohexylenediamine, piperazine, 2-methylpiperazine, phenylenediamine and toluene diamine. , tris (2-aminoethyl) amine, 4,4'-methylenebis (2-chloraniline), 3,3'-dichloro-4,4'-diphenyl diamine, 2,6-diaminopyridine, 4,4 diaminodiphenyl methane, isophorone diamine. The free radical initiator may be an azo initiator such as 2,2'-azobis (2,4-dimethylpentanenitrile) and 2,2'-azobis (2-methylpropanenitrile) [or AIBN]. The radical polymerization of the vinyl monomer mixture and the chain extender of the prepolymer is advantageously carried out at elevated temperature, for example between 50 ° C and 90 ° C, and preferably between 60 ° C and 80 ° C. The amount of chain extender used is advantageously equivalent to the free isocyanate groups in the prepolymer, the ratio of the number of active hydrogens in the chain extender to the number of isocyanate groups in the prepolymer preferably ranging from 0.7 to 1. 3. The polymerization of the vinyl monomers can be carried out according to two methods. According to a first method, the monomers are added and can swell the polyurethane prepolymer before the addition of the tertiary amine. The monomers are then polymerized using the free radical initiator. The proportion of the vinyl monomers can range from 25 to 75%, preferably from 40% to 60%, by weight of the total weight of solids of the aqueous dispersion. According to a second method of polymerization, a part of the vinyl monomers is added to the prepolymer, then neutralized with the tertiary amine and the prepolymer / vinyl monomer mixture is dispersed in water, followed by the polymerization during which the remainder of the monomers. Alternatively, the second monomer portion may be added to the vinyl prepolymer / monomer dispersion after addition of the amine and stir the mixture before the start of the polymerization. The polymer dispersion can contain from 20 to 60% by weight of solids.
