<p>Cosmetic composition comprises at least one carboxyl compound of formulae (I) and (II) and its salt, hydrate, acyclic or cyclic (thio)acetal, (thio)hemiacetal or optical or geometrical isomers. Cosmetic composition comprises at least one carboxyl compound of formulae ((H-C(=O)-C(O)-) nR) (I) or ((H-C(=O)-C(=O)-N-R4) n1-R6-(O-C(=O)-C(=O)-H) m) (II) and its salt, hydrate, acyclic or cyclic (thio)acetal, (thio)hemiacetal or optical or geometrical isomers. R : radical obtained from organic mono- or polyamine; R4 : 1-30C-alkyl, preferably 1-10C-alkyl, 2-30C-alkenyl, preferably 2-10C-alkenyl (where alkyl and alkenyl are optionally interrupted by one or more heteroatoms and/or divalent groups of -O-, -S-, -C(O)- or -N(R1)-, and optionally substituted by one or more groups comprising OH, mercaptan, aldehyde, amino, di-1-10C-alkylamino, dihydroxy-1-10C-alkylamino, 2-10C-acylamido, R1-C(O)-N(R1)-, 2-10C-acyl amido, R1-C(O)-N(R1)-C(O)-, halo, sulfo, carboxyl, cyano or 1-10C-alkoxy) or 6-30C-aryl, preferably phenyl; R1 : H or 1-10C-alkyl; R6 : 1-20C-alkylene, preferably 1-10C-alkylene, 1-20C-alkenylene, preferably 1-10C-alkenylene (where the alkylene or alkenylene are optionally interrupted by one or more heteroatoms and/or divalent groups of -O-, -S-, -C(O)- or -N(R1)-, and optionally substituted by one or more groups comprising OH, mercaptan, aldehyde, amino, di-1-10C-alkylamino, dihydroxy-1-10C-alkylamino, 2-10C-acylamido, R1-C(O)-N(R1)-, 2-10C-acyl amido, R1-C(O)-N(R1)-C(O)-, halo, sulfo, carboxyl, cyano or 1-10C-alkoxy) or arylene, preferably ethylene; n : 1-100; and n1, m : 1-50, preferably 1. An independent claim is included for treating keratin materials, comprising applying the composition to the keratin materials.</p> |
