Abstract:
A cosmetic or dermatological composition comprising, in a cosmetically or dermatologically acceptable vehicle:a) at least one cinnamic acid derivative of formula (I): in which:A is chosen from:an OR3 radical wherein R3 is chosen from a hydrogen atom, a phytyl radical, a benzyl radical, a saturated or unsaturated, linear, branched or cyclic, C1-C18 alkyl chain, an alkali metal ion, an alkaline earth metal ion and an ammonium ion, andan NHR4 radical wherein R4 is chosen from a hydrogen atom, a phytyl radical, a benzyl radical, a saturated or unsaturated, linear, branched or cyclic, C1-C18 alkyl chain, R1 is chosen from a hydrogen atom, a hydroxyl radical, a C1-C6 alkoxy radical, and a saturated or unsaturated, linear, branched or cyclic, C1-C18 alkyl chain;R2 is chosen from a hydrogen atom, a hydroxyl radical, and a C1-C6 alkoxy radical;andb) at least one polyamino polymer chosen from: (A) polyethyleneimines chosen from:(i) polyethyleneimines; (ii) alkylated derivatives of polyethyleneimines; (iii) addition products of alkylcarboxylic acids with polyethyleneimines; (iv) addition products of ketones and aldehydes with polyethyleneimines; (v) addition products of isocyanates and isothiocyanates with polyethyleneimines; (vi) addition products of alkylene oxide and poly(alkylene oxide) block polymers with polyethyleneimines; (vii) quaternized derivatives of polyethyleneimines; (viii) addition products of a silicone with polyethyleneimines; (ix) a copolymer of dicarboxylic acid and polyethyleneimines; (x) hyperbranched polyethyleneimines; (B) polyvinylimidazoles;(C) polyvinylpyridines;(D) addition products of 1-vinylimidazole monomers of formula (I): in which:R radicals are independently chosen from a hydrogen atom and a saturated or unsaturated, linear or cyclic, C1-C6 alkyl radical n is an integer ranging from 1 to 3, with the polyethyleneimines (A)(I) to (A)(x);(E) polymers based on amino acids containing a basic side chain; and(F) crosslinked derivatives of the polymers (A)(I) to (B), (C), (D) and (E).
