Description

COSMETIC COMPOSITION COMPRISING A PARTICULAR SILICONE COPOLYMER, A VOLATILE SOLVENT AND A PARTICULAR AMINO SILICONE The subject of the present invention is a cosmetic composition, in particular intended for the treatment of keratin fibers, such as human keratinous fibers such as the hair, as well as a process for treating keratin fibers using this composition. There are many styling products that can bring body, mass or volume to the hair. A disadvantage related to these products, most often based on film-forming polymers, lies in the fact that the cosmetic effect disappears from the first shampoo. It is possible to make a remanent styling by using a copolymer based on silicone resin and fluid silicone, better known as BioPSA. These copolymers are described in particular in patent applications WO 03/026596, WO 2004/073626, WO 2007/051505 and WO 2007/051506 for various cosmetic applications such as the application to hair, nails, skin. The touch obtained with these copolymers is generally sticky. When the BioPSA polymers are applied to the hair in a volatile solvent, the hair is homogeneously sheathed while remaining individualized, the sheathing obtained being residual to a few shampoos. This sheathing brings to the hair of the body, the mass of a remanent way. Compositions using these polymers are described elsewhere in European Patent Application EP 2,095,810, which relates to a composition comprising one or more copolymers based on silicone resin and fluid silicone, one or more volatile solvents, and one or more silicone resins having at least one trifunctional unit of formula (CH3) SiO312 (T unit). European application EP 2,016,933 may also be mentioned, which concerns, inter alia, the use of anhydrous hair treatment compositions comprising one or more copolymers based on silicone resin and on fluid silicone, one or more linear or cyclic volatile silicones, optionally pigments, and advantageously in the presence of one or more non-volatile linear polydimethylsiloxanes.

In the presence of pigments, these polymers make it possible to obtain a visible coloration regardless of the initial color of the hair, without requiring their prior discoloration. The presence of these pigments, in particular nacres, makes it possible to obtain a chromatic coloration. This color is not yet sufficiently resistant to shampoos.

In the previous cases, however, it has been found that the effect obtained varies according to the state of sensitization of the treated hair. It is important to be able to further improve the remanence of the sheathing effects provided by such copolymers, regardless of the state of the treated fibers.

Thus, one of the aims of the present invention is to develop claddings possibly comprising a colored species, which have a further improved shampoo remanence and which lead to satisfactory results regardless of the type of hair treated.

This object is achieved with the present invention which relates to a cosmetic composition comprising one or more copolymers based on silicone resin and fluid silicone, one or more volatile solvents, and one or more amino silicones comprising one or more functional groups (s). ) intrachain amine (s). The subject of the invention is also a process for treating keratin fibers using the abovementioned cosmetic composition.

The present invention also makes it possible to improve the cosmetic properties of the cladding, in particular the feel of the hair thus sheathed. The hair is softer, more flexible and well individualized. The brushing of the locks during the application is also facilitated.

It has also been possible to observe such effects of remanence and improvement of the cosmetic properties of the hair, when the sheathings comprise pigments. It should also be noted that the composition preserves the physical qualities of the keratin fibers since it makes it possible to obtain persistent, intense and / or chromatic colorings, without the use of oxidizing agents capable of degrading them.

Such polymethylsilsesquioxanes are described in US 5,246,694, the contents of which are incorporated by reference; polypropylsilsesquioxanes, for which the methyl radicals are replaced by propyl radicals. These compounds and their synthesis are described in particular in the patent application WO 2005/075567; polyphenylsilsesquioxanes, for which the methyl radicals are replaced by phenyl radicals. These compounds and their synthesis are described in particular in patent application US 2004/0180011. By way of examples of commercially available polymethylsilsesquioxane resins, mention may be made of those sold: by the company Wacker under the reference Resin MK such as Belsil PMS MK: polymer comprising repeating units CH3SiO312 (T units), which can also comprise up to 1% by weight of (CH3) 2SiO212 units (D units) and having an average molecular weight of about 10,000 g / mol. The polymer is believed to be in a "cage" and "ladder" configuration as shown in the figures below. The average molecular weight of the units in "cage" configuration was calculated at 536 g / mol. The majority of the polymer is in "ladder" configuration with ethoxy groups at the ends. These ethoxy groups represent 4.5% by weight of the polymer.

Advantageously, a diblock copolymer such as those described above, in particular a diblock copolymer of styrene-ethylene / propylene, is used as polymeric thickening agent. More specifically, organophilic clays are clays modified with chemical compounds that make the clay swellable.

Clays are already well known products per se, which are described for example in the book "Clay Mineralogy, S. Caillere, S. Hénin, M. Rautureau, 2nd Edition 1982, Masson", whose teaching is here included for reference. Clays are silicates containing a cation which may be selected from calcium, magnesium, aluminum, sodium, potassium, lithium and mixtures thereof. Examples of such products include clays of the smectite family such as montmorillonites, hectorites, bentonites, beidellites, saponites, as well as the family of vermiculites, stevensite, chlorites . These clays can be of natural or synthetic origin. Preferably, the clays are used which are cosmetically compatible and acceptable with the keratin materials. The organophilic clay may be selected from montmorrilonite, bentonite, hectorite, attapulgite, sepiolite, and mixtures thereof. The clay is preferably a bentonite or a hectorite. These clays may be modified with a chemical compound selected from quaternary amines, tertiary amines, amino acetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates, amine oxides, and mixtures thereof. As organophilic clays, there may be mentioned quaternium-18 bentonites such as those sold under the names Bentone 3, Bentone 38, Bentone 38V by Rheox, Tixogel VP by United catalyst, Claytone 34, Claytone 40, Claytone XL by Southern Clay Company; stearalkonium bentonites such as those sold under the names Bentone 27 by Rheox, Tixogel LG by United Catalyst, Claytone AF, Claytone APA by Southern Clay; quaternium-18 / benzalkonium bentonite such as those sold under the names Claytone HT, Claytone PS by Southern Clay. The fumed silicas can be obtained by high temperature hydrolysis of a volatile silicon compound in an oxyhydrogen flame, producing a finely divided silica. This method makes it possible in particular to obtain hydrophilic silicas which have a large number of silanol groups on their surface. Such hydrophilic silicas are, for example, sold under the names "AEROSIL 130®", "AEROSIL 200®", "AEROSIL 255®", "AEROSIL 300®", "AEROSIL 380®" by the company Degussa, "CAB-O- SIL HS-5® "," CAB-O-SIL EH-5® "," CAB-O-SIL LM-130® "," CAB-O-SIL MS-55® "," CAB-O-SIL M -5® "by the company Cabot. It is possible to chemically modify the surface of said silica, by chemical reaction generating a decrease in the number of silanol groups. In particular, it is possible to substitute silanol groups with hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups may be: trimethylsiloxyl groups, which are especially obtained by treatment of fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are called "silica silylate" according to the CTFA (6th edition, 1995). They are for example sold under the references "AEROSIL R812®" by the company Degussa, "CAB-O-SIL TS-530®" by Cabot. - Dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treatment of fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas thus treated are called "Silica dimethyl silylate" according to the CTFA (6th edition, 1995). They are for example sold under the references "AEROSIL R972®", "AEROSIL R974®" by the company Degussa, "CAB-O-SIL TS-610®", "CAB-O-SIL TS-720®" by the company Pooch.
