Abstract:
A method of lengthening eyelashes, comprising:applying to the eyelashes, an effective amount of a mascara comprising a composition comprising, in a physiologically acceptable medium: at least one first polymer of formula (I): in which:n is an integer which represents the number of amide units such that the number of ester groups present in said at least one structuring polymer ranges from 10% to 50% of the total number of all said ester groups and all said amide groups comprised in said at least one structuring polymer; R1, which are identical or different, are each chosen from alkyl groups with at least 4 carbon atoms and alkenyl groups with at least 4 carbon atoms; R2, which are identical or different, are each chosen from C4 to C42 hydrocarbon-based groups with the proviso that at least 50% of R2 are chosen from C30 to C42 hydrocarbon-based groups; R3, which are identical or different, are each chosen from C2 to C36 hydrocarbon-based group; and R4, which are identical or different, are each chosen from hydrogen, and C1 to C10 alkyl groups, with the proviso that at least 50% of all R4 are chosen from hydrogen; and a dispersion of particles of at least one second polymer that is film-forming and insoluble in said medium.
