CA 2692841

The present invention relates to a cosmetic composition containing a unique polymer blend, which includes: (a) a first polymeric film-former having a first glass transition temperature ranging from about -20°C to about 0°C; (b) a second polymeric film-former having a second glass transition temperature that is at least 50°C higher than the first glass transition temperature; and (c) a third cross-linked polymeric film-former. The cosmetic composition of the present invention can be applied to human skin or keratinous fibers for forming a film thereon with exceptionally long wearability, reduced flaking and smudge properties, and good removability by warm water.

L'invention concerne une composition cosmétique contenant un mélange de polymères unique, comprenant : (a) un premier filmogène polymérique ayant une première température de transition vitreuse dans la plage d'environ -20°C à environ 0°C ; (b) un deuxième filmogène polymérique ayant une deuxième température de transition vitreuse qui est au moins supérieure de 50°C à la première température de transition vitreuse ; et (c) un troisième filmogène polymérique réticulé. La composition cosmétique de la présente invention peut être appliquée sur de la peau humaine ou des fibres de kératine pour former un film dessus ayant une résistance à l'usure exceptionnellement longue, des propriétés d'exfoliation et de maculage moindres, et une bonne aptitude à l'enlèvement par de l'eau chaude.
