Anonyme known as: L'OREAL Anhydrous cosmetic composition comprising a polyester, a volatile oil and a non-volatile oil Invention of: BEBOT Cécile Anhydrous cosmetic composition comprising a polyester, a volatile oil and a non-volatile oil

The present invention relates to an anhydrous cosmetic composition comprising a liquid polyester obtained by condensation of dimer and / or trimer of unsaturated fatty acid and of diol, one or more volatile oils and one or more non-volatile oils, the weight ratio of oil (s) volatile (s) / nonvolatile oil (s) being greater than 1.5, and a process for treating keratin materials, in particular keratinous fibers. Many hair care products have been described in the prior art. The corresponding compositions are intended to provide good cosmetic properties to the hair.

However, it appears very difficult to formulate hair products to bring a good level of shine to the hair without causing a very anticosmetic fatty or tacky effect. Document EP 1 857 098 also discloses a cosmetic composition for makeup and / or care of keratin materials comprising an ester of polyol (s) and dimer of fatty acid diacid and a particular polyamide. The Applicant has surprisingly discovered that the combination in an anhydrous medium of one or more liquid polyesters obtained by condensation of dimer and / or trimer of unsaturated fatty acid and of diol, a volatile oil and an oil nonvolatile in a weight ratio volatile oil / nonvolatile oil greater than 1.5 allowed to avoid the problems encountered in the prior art and to obtain a hair care composition to bring a good level of shine to the hair while limiting the fat effect. The subject of the present invention is therefore an anhydrous cosmetic composition comprising one or more liquid polyesters obtained by condensation of dimer and / or trimer of unsaturated fatty acid and of diol, one or more volatile oils and one or more non-volatile oils, the weight ratio volatile oil (s) / non-volatile oil (s) being greater than 1.5. Liquid polyester means a polyester whose viscosity is less than 40000 Cst, preferably less than 20000 Cst at 40 ° C, determined according to ASTM D445-88. In the context of the present invention, the term "unsaturated fatty acid" denotes a mono- or polyunsaturated fatty acid comprising from 14 to 22 carbon atoms. The unsaturated fatty acid dimers may in particular comprise from 2 to 4 unsaturations in their carbon chain. The unsaturated fatty acid trimers may comprise from 3 to 6 unsaturations in their carbon chain. Preferably, the unsaturated fatty acid dimers and / or trimers are polycarboxylic acids comprising at least 2 and up to 6 carboxylic acid functions per molecule. In a preferred embodiment, the unsaturated fatty acid dimer may comprise from 28 to 44 carbon atoms and preferably 2 carboxylic acid functions. The unsaturated fatty acid trimer can comprise from 42 to 66 carbon atoms and preferably 3 carboxylic acid functions. Preferably, an unsaturated fatty acid dimer is used, in particular having 36 carbon atoms and 2 carboxylic acid functions. Mixtures of dimers and trimers of unsaturated fatty acids and / or unsaturated fatty acids (unpolymerized, therefore corresponding to the monomers) can also be used within the scope of the invention. In the case of such a mixture, a mixture comprising more than 50% by weight of dimers, for example a mixture comprising more than 90% by weight, preferably more than 95%, of acids in the form of dimers, is preferred. the remainder of the mixture may be trimers and / or unsaturated fatty acid monomers. The dimer and / or trimer of unsaturated fatty acid may optionally be hydrogenated after the polymerization reaction of the unsaturated fatty acid, in particular to improve the stability of the dimer or trimer product. Hydrogenated fatty acid dimers (oleic or linoleic acid) are especially marketed under the trade names EMPOL1008, EMPOL1004, EMPOL1025, EMPOL1011 and EMPOL1062 by Cognis and Pripol 1006 (dilinoleic acid) by Uniqema, International. Uniqema also markets a hydrogenated fatty acid dimer under the name Pripol 1013 (hydrogenated dilinoleic acid). In a particularly preferred manner, the unsaturated fatty acid dimer is a dimer of linoleic acid, also called dilinoleic acid, obtained by intermolecular polymerization of linoleic acid.

The unsaturated fatty acid may be of natural origin, preferably vegetable. A fatty acid of plant origin can come from any plant source producing said fatty acid. For example, in the case of linoleic acid, molecules extracted from soybean, rapeseed, etc. may be used.
