Abstract:
A cosmetic and/or dermatological composition comprising, in a cosmetically and/or dermatologically acceptable vehicle:a) at least one polyamino polymer selected from:(A) a polyalkylene polyamine polymers selected from:(i) polyalkylene polyamines;(ii) alkylated derivatives of polyalkylene polyamines;(iii) addition products of alkylcarboxylic acids with polyalkylene polyamines (A)(i);(iv) addition products of ketones and aldehydes with polyalkylene polyamines (A)(i);(v) addition products of isocyanates and isothiocyanates with polyalkylene polyamines (A)(i);(vi) addition products of alkylene oxide and poly(alkylene oxide) block polymers with polyalkylene polyamines (A)(i);(vii) quaternized derivatives of polyalkylene polyamines (A)(i);(viii) addition products of a silicone with polyalkylene polyamines (A)(i);(ix) a copolymer of dicarboxylic acid and polyalkylene polyamines (A)(i);(B) polyvinylimidazoles;(C) polyvinylpyridines;(D) addition products of 1-vinylimidazole monomers of formula (I): ##STR18##in which:R radicals independently represent H or a saturated or unsaturated, linear or cyclic, C.sub.1 -C.sub.6 alkyl radical,n is an integer ranging from 1 to 3, with polyalkylene polyamines (A)(i) to (A)(ix);(E) polymers based on amino acids containing a basic side chain; and(F) crosslinked derivatives of the polymers (A)(i) to (A)(ix), (B), (C), (D) arid (E); and b) at least one dibenzoylmethane derivative corresponding to the following formula (V): ##STR19##in which:R.sub.7, R.sub.8, R.sub.9, and R.sub.10, independently represent hydrogen or a hydroxyl radical or a linear or branched C.sub.1 -C.sub.8 alkyl radical or a linear or branched C.sub.1 -C.sub.8 alkoxy radical wherein the at least of polyamino polymer improves the photostability of the cosmetic and/or dermatological composition as compared to the photostability of a cosmetic and/or dermatological composition absent at least one polyamino polymer.
