A cosmetic composition is provided which includes a silicone elastomer, a cationic copolymer with monomeric units selected from at least an acryloylethyl tri(C1-C3 alkyl)ammonium salt and light reflecting platelet shaped particles. The com-positions are particularly useful to impart radiance as well as soft focus effects onto the skin. A particularly useful cationic copoly-mer is acrylamide/acryloylethyl trimethylammonium chloride/tris(hydroxymethyl) acrylamidomethane copolymer.
L'invention concerne une composition cosmétique qui comprend un élastomère de silicone, un copolymère cationique à unités monomères sélectionnées parmi au moins un sel d'acryloyléthyle tri(C1-C3 alkyl)ammonium et des particules en forme de plaquette réfléchissant la lumière. Ces compositions sont particulièrement utiles afin d'appliquer une luminance ainsi que des effets de flou sur la peau. Un copolymère cationique particulièrement utile consiste en un copolymère d'acrylamide/de chlorure d'acryloyléthyle triméthylammonium/de tris(hydroxyméthyl) acrylamidométhane.
