abstract |
The present invention relates to a cosmetic composition comprising: -one or more keratin fibre conditioning agents; -one or more polymers of formula (I): in which: -Z 1 represents a divalent group -CH 2 -T or -T-CH 2 -; T denoting an oxygen or sulfur atom, or a group chosen from the groups N(R 2 ), N(R 2 )-C(O), C(O)-N(R 2 ), S-(CO), (CO)-S, O-(CO) and (CO)-O; -Z 2 represents a group OR 1 or R 8 –CH 2 -NR 3 R 4 ; -Z 3 represents a group OR 5 or R 6 ; -p1 is equal to 1; -p2 is equal to 0 or 1; -R 2 and R 3 , which may be identical or different, represent a hydrogen atom or a group R7; R 1 , R 5 , R 6 , R 7 and R 8 , which may be identical or different, represent a C 1 -C 6 and preferably C 1 -C 2 alkyl group; and R 4 represents a C 1 -C 6 and preferably C 1 -C 2 alkyl group, or a C 5 -C 6 and preferably C 6 cycloalkyl group such as cyclohexyl; R 3 and R 4 may optionally form, with the nitrogen atom that bears them, a 5-to 8- membered heterocycle comprising from 1 to 3 heteroatoms; -W represents a divalent polymer chain. The invention also relates to processes using this composition with or without catalysts and devices. |
