The subject-matter of the present invention is the use, in and for the preparation of cosmetic or dermatological compositions, of a grafted copolymer, the skeleton (S) of which is composed of a hydrophilic copolymer, with a glass transition temperature Tg greater than 25.degree. C., obtained by radical polymerization or by polycondensation, comprising, on the chain of the skeleton (S), at least one graft composed of a hydrophobic macromonomer (M) with a glass transition temperature T'g of less than 25.degree. C., as well as the cosmetic or dermatological compositions employed.

A assunto-matéria da invenção atual é o uso, e para na preparação de composições cosmetic ou dermatological, de um copolymer grafted, o (S) de esqueleto de que é composto de um copolymer hydrophilic, com uma temperatura de transição de vidro Tg mais grande do que 25.degree. C., obtido pela polimerização radical ou pelo polycondensation, compreendendo, na corrente do (s) de esqueleto, ao menos um graft composto de um macromonomer hydrophobic (M) com uma temperatura de transição de vidro T'g de menos do que 25.degree. C., as.well.as o cosmético ou as composições dermatological empregado.
