COMPOSITION WHICH MAKES POSSIBLE THE RELEASE OF A BENEFICIAL AGENT COMPRISING A WATER-INSOLUBLE CYCLODEXTRIN POLYCONDENSATE AND AT LEAST ONE BENEFICIAL AGENT
The present invention relates to a composition which makes possible the release of a beneficial agent comprising at least one beneficial agent and a support comprising at least one water-insoluble cyclodextrin polycondensate which can be obtained by esterification/polycondensation reaction: A) of at least one cyclodextrin and B) of at least one saturated or unsaturated or aromatic, linear or branched or cyclic polycarboxylic acid and/or at least one ester or one acid anhydride or one acid halide of said polycarboxylic acid and C) of at least one thermoplastic polyol polymer and D) optionally of at least one esterification catalyst and/or E) optionally of at least one cyclic anhydride of a polycarboxylic acid chosen to be other than the polycarboxylic acid anhydride of paragraph B) and/or F) optionally of at least one non-polymeric polyol comprising from 3 to 6 hydroxyl groups. Another subject-matter of the invention consists of a consumer product comprising at least one composition which makes possible the release of a beneficial agent as defined previously, in particular a cosmetic or dermatological composition comprising a physiologically acceptable medium. In addition, the invention relates to a process for cosmetic treatment of a keratin material, consisting in applying, to the surface of said human keratin material, a consumer product comprising a composition as defined above containing, in a physiologically acceptable medium, at least one beneficial agent chosen from cosmetic active agents.La présente invention concerne une composition qui rend possible la libération dun agent bénéfique et qui comprend au moins un agent bénéfique et un support comprenant au moins un polycondensat de cyclodextrine insoluble dans leau qui peut être obtenu par réaction destérification/de polycondensation : A) dau moins une cyclodextrine et B) dau moins un acide polycarboxylique saturé, insaturé ou aromatique, linéaire, ramifié ou cyclique et/ou dau moins un ester ou un anhydride
