Summary:In a cosmetic composition containing an aqueous phase, a combination of at least one oxidation sensitive hydrophilic active principle (a) and at least one maleic anhydride copolymer (b) are used as depigmenting agents. (a) Is ascorbic acid or its derivatives. (b) Comprises at least one maleic anhydride comonomers and at least one of e.g. vinyl acetate, vinyl alcohol or styrene. In a cosmetic composition containing an aqueous phase, a combination of at least one oxidation sensitive hydrophilic active principle (a) and at least one maleic anhydride copolymer (b) are used as depigmenting agents. (a) Is ascorbic acid or its derivatives. (b) Comprises at least one maleic anhydride comonomers and at least one of vinyl acetate, vinyl alcohol, vinyl alcohol, vinyl pyrrolidone, olefins containing 2-20C atoms or styrene. L'invention se rapporte à une composition à usage topique contenant au moins un actif hydrophile sensible à l'oxydation et au moins un copolymère d'anhydride maléique comportant un ou plusieurs co-monomères anhydride maléique et un ou plusieurs co-monomères choisis parmi l'acétate de vinyle, l'alcool vinylique, la vinylpyrrolidone, les oléfines comportant de 2 à 20 atomes de carbone, et le styrène, dans un milieu physiologiquement acceptable comprenant une phase aqueuse. L'invention se rapporte également à l'utilisation d'un copolymère d'anhydride maléique tel que défini ci-dessus pour stabiliser un actif hydrophile sensible à l'oxydation, en particulier en phase aqueuse.
