| abstract |
The invention relates to a physiologically acceptable, in particular mascara, cosmetic composition comprising at least one volatile solvent and at least one polymer chosen from polymers of following formula (I): n n nin which n denotes a number of amide units, such that the number of ester groups represents from 10% to 50% of the total number of ester and amide groups: R 1 is in each case, independently an alkyl or alkenyl group having at least 4 carbon atoms; R 2 independently represents in each case a C 4 to C 42 hydrocarbonaceous group, provided that 50% of the R 2 groups represent a C 30 to C 42 hydrocarbonaceous group; R 3 independently represents, in each case, an organic group provided with at least 2 carbon atoms, with hydrogen atoms and optionally with one or more oxygen or nitrogen atoms; and R 4 independently represents, in each case, a hydrogen atom a C 1 to C 10 alkyl group or a direct bond to R 3 or another R 4 , so that the nitrogen atom to which both R 3 and R 4 are bonded forms part of a heterocyclic structure defined by R 4 —N—R 3 with at least 50% of the R 4 groups representing a hydrogen atom. |
