Description

COSMETIC COMPOSITION THAT COMPRISES AN ACRYLIC ANIONIC POLYMER AND A SILICONE? OXIALZÜILZNADA.

The present invention relates to cosmetic compositions containing, in a cosmetically acceptable medium, at least one acrylic anionic fixing polymer and at least one particular oxyalkylenated silicone. The subject of the invention is also a method for the cosmetic treatment of keratin materials, such as hair or eyelashes, characterized in that it consists of applying a cosmetic composition on the keratin materials as defined above, then optionally rinsing with water . The compositions for maintaining or shaping the hair containing their styling polymer formulation (fixing polymers) generally have the drawback of making it difficult to disentangle, re-comb or brush the hair, in particular during the brush marking. Some polymers also have the disadvantage of dusting the hair (presence of white films) during brushing or styling after drying the polymer.

REF: 26067 The association of silicone derivatives with fixative polymers is known in cosmetic compositions for the maintenance and / or fixation of the hairstyle. It has been observed that these silicone derivatives improve the disentangling, softness and gloss properties of the treated hair with the help of these compositions. However, on the one hand, the silicone derivatives are not favorable for the combing and / or fixing properties of the compositions containing fixative polymers, and on the other hand, the disentangling and softness properties are still not satisfactory. The purpose of the present invention is therefore to propose compositions that allow to fix and / or shape the hairstyle, these compositions having a good fixing power, good behavior properties over time, provide good touch properties and disentangling. In addition, they must form an invisible deposit on the hair and do not dust during brushing or combing. On the other hand it is known from the patent application EP 260 641, compositions for particular hairstyles in which specific silicone polymers (comprising a maximum of 90 SiO units) are associated with combing polymers in particular emulsions comprising at least one surfactant nonionic having a HLB value greater than or equal to 10 and an ionic surfactant. The proposed examples clearly express that when they weakly deviate from this particular formulation in the form of an emulsion, both the fixative and cosmetic properties of these compositions are diminished. However, the applicant now has just discovered that cosmetic compositions containing, in a cosmetically acceptable medium, at least one acrylic anionic polymer and at least one particular oxyalkylenated silicone unexpectedly and surprisingly allowed to obtain the properties described above, a touch more natural, and a good behavior of the hairstyle with time, and this without needing the use of a composition in the form of emulsion with very particular surfactants. The subject of the present invention is therefore a novel cosmetic composition characterized in that it comprises, in a cosmetically acceptable medium, at least one anionic fixing polymer derived from acrylic or methacrylic acid and at least one particular oxyalkylenated silicone described below. By "fixating polymer", it is understood according to the invention any polymer whose main function is to temporarily fix the shape of the hairstyle.

The anionic fixing polymer derived from acrylic or methacrylic acid which can be used according to the present invention is chosen from the following polymers: A) the homopolymers of acrylic or methacrylic acid or their salts and in particular the products sold under the names VERSICOL E or K by the company ALLIED COLLOID.

DOW CORNING. The one or more anionic fixing polymers are generally present in concentrations of between 0.1% and 20% by weight, and preferably in concentrations of between 1% and 10% by weight relative to the total weight of the composition. The oxyalkylenated silicone (s) may be present in concentrations ranging from 0.001% and 10% by weight, and preferably in concentrations comprised between 0.005% and 3% by weight relative to the total weight of the composition. The cosmetically acceptable medium generally comprises solvents compatible with the fixing polymer and the oxyalkylenated silicone. These solvents are, for example, water, alcohols, acetone, which can be used alone or as a mixture. Preferably, alcohols of 1-6 carbon atoms are used. Among the alcohols, mention may be made of ethanol, isopropanol, polyalcohols such as diethylene glycol, glycol ethers, glycol onoalkyl ethers, diethylene glycol, propylene glycol or dipropylene glycol. Ethanol is particularly preferred. The compositions according to the invention are preferably free of water, that is to say they contain less than 8% by weight of water relative to the total weight of the composition and preferably less than 5%. The drying of the compositions is thus faster The composition of the invention can also contain at least one additive selected from thickeners, fatty acid esters, fatty acid esters and glycerol, silicones, surfactants, perfumes, preservatives, sunscreens, proteins, vitamins, polymers, vegetable, animal, mineral or synthetic oils and any other additive classically used in the cosmetic field.

The compositions according to the invention can be in the form of gels, of milks, of creams, of dispersions, of emulsions, of more or less thick lotions or of foams. The compositions according to the invention are used more particularly as non-rinsed products, particularly for the maintenance of styling, shaping or combing of the hair. They are more particularly marking lotions, lotions for brush marking, fixing compositions (lacquers) and styling. The lotions may be conditioned in various forms, particularly in vaporizers, sprays, or in aerosol containers in order to ensure application of the composition in vaporized form i in the form of foam. Such forms of conditioning are indicated, for example, when it is desired to obtain a spray, a lacquer or a foam for fixing or treating the hair. When the composition according to the invention is packaged in the form of an aerosol in order to obtain a lacquer or an aerosol foam it comprises at least one propellant which can be chosen from volatile hydrocarbons such as n-butane, propane, isobutane , a chlorinated and / or fluorinated hydrocarbon and its mixtures. It is also possible to use carbon dioxide, nitrous oxide, dimethyl ether, nitrogen, compressed air and mixtures thereof as the propellant. The propellant concentration is generally between 10 and 90% by weight relative to the total weight of the pressurized composition and preferably between 15 and 70% by weight relative to the total weight of the composition. Another subject of the invention is a method for the cosmetic treatment of keratin materials, such as hair or eyelashes, consisting of applying a composition as defined above to these, then optionally rinsing with water.
