Patent ID: 7582286

Claim:
A cosmetic composition comprising, at least one cosmetically acceptable solvent, and at least one photoactivatable diazirine-active agent compound which comprises a diazirine covalently bonded to a cosmetic active agent, wherein the cosmetic agent is chosen from natural soluble polymers, synthetic soluble polymers, natural insoluble polymers, synthetic insoluble polymers, sunscreens, mineral particles, organic particles, antioxidants, and dyes, and wherein the diazirine is chosen from diazirines of formula (I): wherein: —R 1 is chosen from a hydrogen atom, linear and branched C 1 to C 10 alkyl radicals, linear and branched C 2 to C 10 alkenyl radicals, linear and branched C 2 to C 10 alkynyl radicals, CF 3 , CCl 3 , CBr 3 , N(R′) 3 +, S(R′) 2 +, SH 2 +, NH 3 +, NO 2 , SO 2 R′, C≡N, COOH, F, Cl, Br, I, OR′, COOR′, SO 3 H, COR′, SH, SR′ and OH radicals, wherein R′ is chosen from C 1 to C 10 alkyl radicals; —Z is chosen from a single bond and a spacer group, wherein the spacer group is a carbon-based chain chosen from linear, branched and cyclic, saturated C 1 -C 100 carbon-based chains, wherein said carbon-based chain may be interrupted with at least one hetero atom and may also comprise at least one substituent; —Y is an aldehyde, and —Ar is an aromatic nucleus: wherein: —R 2 , R 3 , R 4 and R 5 , which may be identical or different, are each chosen from a hydrogen atom, linear and branched C 1 to C 10 alkyl radicals, linear and branched C 2 to C 10 alkenyl radicals, linear and branched C 2 to C 10 alkynyl radicals, CF 3 , CCl 3 , CBr 3 , N(R′) 3 +, S(R′) 2 +, SH 2 +, NH 3 +, NO 2 , SO 2 R′, C≡N, COOH, F, Cl, Br, I, OR′, COOR′, COR′, SH, SR′, OH and SO 3 H radicals, wherein R′ is chosen from C 1 to C 10 alkyl radicals.
