Abrégé
(EN)
The invention concerns a cosmetic composition for skin make-up and/or care comprising a dispersion, in a cosmetically acceptable medium, of particles containing at least a soft phase at least internally including at least a soft polymer having a glass transition temperature not more than 60 °C and at least a rigid phase at least externally which is an amorphous material having a glass transition temperature higher than 60 °C, the soft polymer being fixed at least partly by chemical grafting on the rigid phase. The invention also concerns the use of such a dispersion of particles to enhance the comfort and resistance of cosmetic compositions.
(FR)
L 'invention se rapporte a une composition cosmétique de maquillage et/ou de soin de la peau comprenant une dispersion, dans un milieu cosmétiquement acceptable, de particules comprenant une phase souple au moins en partie interne comportant au moins un polymère souple ayant une température de transition vitreuse intérieure ou égale a 60°C et une phase rigide au moins en partie externe qui est un matériau amorphe ayant une température de transition vitreuse supérieure a 60°C, le polymère souple étant fixe au moins partiellement par greffage chimique sur la phase rigide. L 'invention se rapporte aussi a l'utilisation d'une telle dispersion de particules pour améliorer le confort et la tenue des compositions cosmétiques.
