Use of polyamide polymer in a mascara composition comprising at least one inert filler

摘要

A physiologically acceptable, in particular mascara, cosmetic composition comprising at least one polymer, such as a structuring polymer, chosen from polymers of following formula (I): in 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; R¹ is, in each case, independently an alkyl or alkenyl group having at least 4 carbon atoms; R² independently represents, in each case, a C₄ to C₄₂ hydrocarbonaceous group, provided that 50% of the R² groups represent a C₃₀ to C₄₂ hydrocarbonaceous group, R³ 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 R⁴ independently represents, in each case, a hydrogen atom, a C₁ to C₁₀ alkyl group or a direct bond to R³ or another R⁴, so that the nitrogen atom to which both R³ and R⁴ are bonded forms part of a heterocyclic structure defined by R⁴-N-R³, with at least 50% of the R⁴ groups representing a hydrogen atom and at least one inert filler.
