Description

Cosmetic composition comprising a sugar alcohol and a copolymer

  of acrylate (s) or methacrylate (s) and hydroxyester of acrylate (s) or methacrylate (s), as well as its use as a hair product.

  The present invention relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one alcoholic sugar, and at least one copolymer of acrylate (s) or of acrylate methacrylate (s) and of acrylate (s) or methacrylate (s).

  The present invention also relates to a cosmetic hair treatment method using the aforementioned composition, and a use of this cosmetic composition as a hair product, for example as a styling product. Hair styling products are usually used to build, structure the hairstyle and give it a lasting hold. The corresponding compositions generally comprise one or more film-forming polymers in a cosmetically acceptable medium. These polymers allow the formation of a sheathing film on the hair, thus ensuring the maintenance of the hairstyle.

  However, the fixing polymer films thus formed have the disadvantage of being relatively friable, which limits in time the holding of the hairstyle, and causes the formation on the hair of unsightly residues. To reduce these problems of friability, it is known to incorporate in the styling products based on film-forming polymers a plasticizer such as a glycol. This effectively improves the behavior of the hairstyle over time and limit the formation of residues during the day. However, despite the addition of such a plasticizer, the non-friability of the polymer films is generally related to the fixing polymer concentration in the styling product (or degree of fixation): if the polymer concentration is decreased fixing to reduce the rigidity of the hairstyle, then the polymer film becomes more friable and holding the hairstyle is less good. There is therefore a need for hair compositions that make it possible to obtain a lasting hold of the hairstyle, whatever the degree of fixation. The Applicant has now discovered, surprisingly, that the combination of a particular fixing polymer, of the (meth) acrylate (s) / hydroxyester (meth) acrylate (s) type, with a sugar alcohol, made it possible to obtain a hair composition providing improved styling properties. In particular, such an association makes it possible to obtain hair styling products providing a range of flexible to ultra-strong bindings, with an extremely low-friable polymer film, whatever the degree of fixation. It thus becomes possible to formulate long-lasting flexible fastening products. The present invention makes it possible in particular to prepare hair styling products that provide significantly improved hairstyling durability, including in products with flexible fixation, that is to say with a low concentration of fixing polymer.

  Moreover, and quite unexpectedly, the compositions according to the invention have been found to provide a very marked improvement in the cosmetic properties of the hair after disentangling: the hair is much softer and less dry than after the application of a conventional fixing product.

  The subject of the present invention is therefore a cosmetic composition comprising, in a cosmetically acceptable medium, at least one sugar alcohol, and at least one copolymer of acrylate (s) or of methacrylate (s) and of acrylate hydroxy ester (s). ) or methacrylate (s).
