Composition for the release of beneficial comprising a polycondensate of cyclodextrin insoluble in water and at least one agent beneficial

摘要

The present invention relates to a composition for the release of beneficial agent comprising at least one beneficial agent and a support comprising at least one polycondensate of cyclodextrin, insoluble in water, which can be obtained by esterification reaction / polycondensation: a) of at least one cyclodextrin and b) of at least one polycarboxylic acid, linear or branched or cyclic, saturated or unsaturated or aromatic and / or at least one ester or an acid anhydride or an acid halide of the polycarboxylic acid, and c) of at least one thermoplastic polymer polyol and d), optionally at least one esterification catalyst and / or e), optionally at least one polycarboxylic acid cyclic anhydride selected to be different from the dicarboxylic acid anhydride (b) and / or f), optionally at least one polyol a polymer comprising from 3 to 6 hydroxyl groups. Another object of the invention consists of a consumer product comprising at least one composition permitting the release of beneficial agent as defined above, in particular a cosmetic or dermatological composition containing a physiologically acceptable medium. The present invention also relates to a process for the cosmetic treatment of keratinous material, consisting in applying on the surface of the keratinous material a product such as defined above.
