Abstract
(EN)
A cosmetic composition suitable for topical application to the skin comprising: (a) a polyol carboxylic acid ester having a polyol moiety and at least 4 carboxylic acid moieties, wherein the polyol moiety is selected from sugars and sugar alcohols containing from about 4 to about 8 hydroxyl groups, and wherein each carboxylic acid moiety has from about 2 to about 30 carbon atoms, and; (b) an emollient material selected from compounds having formula (I) wherein R1 is a C2-C13 straight or branched chain alkyl and R2 is independently selected from a C1-C20 straight chain or branched chain alkyl, and; (c) a non-ionic thickening agent selected from polyacrylamide polymers, cross-linked poly(N-vinylpyrrolidones), and mixtures thereof. The compositions of the invention provide improved rheological, absorption and insulation properties in addition to good skin feel, skin softness and skin smoothness benefits.
(FR)
L'invention concerne une composition cosmétique convenant pour une application topique sur la peau, qui renferme: (a) un ester d'acide carboxylique de polyol comportant une fraction de polyol et au moins 4 fractions d'acide carboxylique, la fraction de polyol étant sélectionnée entre des sucres et des alcools de sucre contenant d'environ 4 à environ 8 groupes hydroxyle, et chaque fraction d'acide carboxylique possédant d'environ 2 à environ 30 atomes de carbone; (b) une matière émolliente sélectionnée dans le groupe des composés représentés par la formule (I), dans laquelle R1 est un alkyle à chaîne droite ou ramifiée en C2-C13 et R2 est sélectionné indépendamment entre un alkyle à chaîne droite et un alkyle à chaîne ramifiée en C1-C20; et (c) un agent épaississant non ionique sélectionné dans le groupe constitué par des polymères de polyacrylamide, des poly(N-vinylpyrrolidones) réticulées et des mélanges de ceux-ci. Les compositions de l'invention confèrent des propriétés rhéologiques, d'absorption et d'isolation améliorées, sont en outre agréables au toucher et rendent la peau souple et douce.
