Claim:
A cosmetic composition comprising, in a cosmetically acceptable medium, at least one compound of formula (I): wherein: n is 1, 2, 3 or 4; R1, R′1, R2 and R′2, which may be identical or different, are H, —OH, —NRR′ wherein R and R′, are independently H or a linear or branched C1-C12 alkyl radical; or a linear, branched and/or cyclic, saturated or unsaturated, optionally aromatic, C1-C18 carbon group which optionally comprises one or more heteroatoms selected from the group consisting of O, S and N; p and q are, independently of one another, integers between 1 and 16; X and X′ are, independently of one another, —O— or —NH— Z is a multivalent radical selected from the group consisting of: (i) a linear or branched, saturated or unsaturated, C1 to C32 carbon radical, optionally interrupted or substituted, one or more times, with an optionally aromatic C3-C12 (hetero)cycle; or (ii) an optionally aromatic C3-C12 (hetero)cyclic carbon-radical, optionally substituted with one or more linear or branched, saturated or unsaturated, C1 to C32 carbon-based radicals; wherein Z is optionally: substituted with 1 to 12 groups selected from the group consisting of —OH, —SO 3 R, —OSO 3 R, —SO 3 H, —OSO 3 H, —COOH, —COOR, —CONRR′ and —N + RR′R″, wherein R, R′ and R″ are independently C1-C12 alkyl, and/or interrupted with 1 to 12 groups selected from the group consisting of: —S—, —NH—, —O—, —C(O)—, —SO 2 —, wherein R′ and R″, which may be identical or different, are a hydrogen atom or a linear, branched and/or cyclic, saturated or unsaturated, carbon radical containing 1 to 22 carbon atoms, (i) optionally substituted with one or more groups selected from the group consisting of —SO 3 R 1 , —OSO 3 R 1 , —COOR 1 , —Si(OR 1 ) 3 , —N + R 1 R 2 R 3 or —NR 1 R 2 , in which R 1 , R 2 and R 3 , independently of one another, are H or C1-C22, alkyl, and optionally interrupted with at least one selected from the group consisting of —NH, —O— and —C(O)—; the following trivalent groups: wherein R′ is defined above the trivalent groups are present at the junction of the radicals; with the proviso that the Z radical comprises at least one substitution group selected from the group consisting of: —OH, —COOH, CONRR′ and —N + RR′R″; or at least one interruption group selected from the group consisting of: —S—, —NH—,
