Abstract:
A process for treating a keratinous substance, comprising applying to said keratinous substance a composition, comprising, in a physiologically acceptable medium, at least one polymer having a star structure chosen from structures of formula (I):Aâ€”[(M1)p1â€”(M2)p2 . . . (Mi)pj]nâ€ƒâ€ƒ(I) in which:A is chosen from polyfunctional centers having a functionality n; [(M1)p1â€”(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; and 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 10Â° C.; and wherein said at least one polymerized monomeric unit Mi chosen from polymerized monomeric units Mk is present in an amount ranging from 45 to 99 percent by weight relative to the total weight of the polymerized monomeric units Mi.
