Abstract:
A composition comprising the combination of:(A) at least one retinoid selected from the group consisting of vitamin A and the bioconvertible precursors of vitamin A; and (B) at least one polyamine polymer selected from the group consisting of: (A) a polyalkylenepolyamine selected from the group consisting of: (i) alkylated polyalkylenepolyamines; (ii) products of addition of alkylcarboxylic acids to the polyalkylenepolyamines; (iii) products of addition of ketones and of aldehydes to the polyalkylenepolyamines; (iv) products of addition of isocyanates and of isothiocyanates to the polyalkylenepolyamines; (v) products of addition of alkylene oxide or of polyalkylene oxide block polymers to the polyalkylenepolyamines; (vi) quaternized derivatives of polyalkylenepolyamines; (vii) product of addition of a silicone to the polyalkylenepolyamines; (viii) a copolymer of dicarboxylic acid and polyalkylenepolyamines; (B) polyvinylimidazole; (C) polyvinylpyridines; (D) products of addition of 1-vinylimidazole monomers of formula (I): â€ƒin which the R radicals, which are identical or different, represent H, or a linear or cyclic, saturated or unsaturated C1-C6 alkyl radical and n is an integer ranging from 1-3, to the polyalkylenepolyamines (A)(i) to (A)(viii); (E) polymers based on amino acids containing a basic side chain; and (F) cross-linked derivatives of the polymers (A)(i) to (A)(viii), (B) (C) (D) and (E).
