Abstract

Emulsion directe comprenant un filtre UV, un polymère acrylique lipophile, un ester d’acide gras et de polyol et un dérivé d’acide aminé La présente invention concerne une composition, notamment cosmétique ou dermatologique, sous la forme d’une émulsion huile-dan-eau, comprenant : - au moins un filtre UV ; - au moins un polymère comprenant des unités monomériques de formules (A) et (B) : dans lesquelles : R1, indépendamment l’un de l’autre, est choisi parmi les radicaux alkyle ou alcényle, et au moins 60 % en poids des groupes R1 sont des radicaux choisis parmi les radicaux stéaryle et béhényle, le pourcentage en poids se rapportant à la somme de tous les groupes R1 présents dans le polymère, et le ratio pondéral de la somme de toutes les unités acrylate d’hydroxyéthyle sur la somme de toutes les unités acrylates portant le groupe R1 va de 1 :30 à 1 : 1 ; et la somme du total des unités A et B est d’au moins 95 % en poids du poids total du polymère, le polymère ayant un poids moléculaire moyen en nombre Mn allant de 2 000 à 9 000 g/mol ; - au moins un ester d’acide gras en C12-C24 et de polyol en C2-C24 ; et - au moins un tensioactif choisi parmi les acides aminés modifiés par au moins une chaîne hydrocarbonée en C8-C30 et leurs sels. La présente invention permet d’accéder à une composition présentant un fort pouvoir protecteur anti-UV, qui soit stabilisée dans le temps, et qui présente par ailleurs de bonnes propriétés cosmétiques telles qu’un pouvoir rafraichissant et une texture non grasse et non collante.Direct emulsion comprising a UV filter, a lipophilic acrylic polymer, a fatty acid ester of polyol and an amino acid derivative The present invention relates to a composition, in particular cosmetic or dermatological, in the form of an oil-in-water emulsion, comprising: - at least one UV filter; - at least one polymer comprising monomeric units of formulae (A) and (B): in which: R1, independently of one another, is chosen from alkyl or alkenyl radicals, and at least 60% by weight of the R1 groups are radicals chosen from stearyl and behenyl radicals, the percentage by weight relating to the sum of all the R1 groups present in the polymer, and the weight ratio of the sum of all the hydroxyethyl acrylate units to the sum of all the acrylate units bearing the R1 group ranges from 1:30 to 1:1; and the sum of the total of units A and B is at least 95% by weight of the total weight of the polymer, the polymer having a number-average molecular weight Mn ranging from 2,000 to 9,000 g/mol; - at least one ester of C12-C24 fatty acid and C2-C24 polyol; and - at least one surfactant chosen from amino acids modified by at least one C8-C30 hydrocarbon chain and their salts. The present invention makes it possible to provide a composition having a strong anti-UV protective power, which is stabilized over time, and which also has good cosmetic properties such as a refreshing power and a non-greasy and non-sticky texture.
