Abstract:
A composition, comprising, in a physiologically acceptable medium, at least one polymer having a star structure chosen from structures of formula (I):A-[(M1)p1-(M2)p2 . . . (Mi)pj]nâ€ƒâ€ƒ(I) in which:A is chosen from polyfunctional centers having a functionality n; [(M1)p1-(M2)p2 . . . (Mi)pj] represents a branch comprising at least one polymerized monomeric unit Mi having a polymerization index pj; n is an integer greater than or equal to 2; pj is greater than or equal to 2; there are at least two branches which may be identical or different; and said at least two branches are grafted covalently to A; wherein said at least one polymerized monomeric unit Mi comprised by at least one of said at least two branches is chosen from polymerized monomeric units Mk, which may be identical or different, wherein a homopolymer formed by the corresponding polymerized monomeric units Mk has a Tg of greater than or equal to 0Â° C.; and wherein said at least one polymerized monomeric unit Mi contained by at least one of said at least two branches is chosen from polymerized monomeric unit Mj, which may be identical or different, wherein a homopolymer formed by the corresponding polymerized monomeric units Mj has a Tg of less than or equal to 0Â° C.; wherein said composition is in the form of a make-up product for the face or body chosen from lipsticks, foundations, face powders, eyeshadows, eyeliners, and mascaras.
