Composition that contains, in a physiologically acceptable medium that includes a fatty phase, at least one first polyamide polymer with a weight average molecular mass of less than 100,000, consisting of a) a polymeric skeleton containing repetitive units of amide and b) possibly at less a pendant fatty chain and / or at least one terminal fatty chain, which may be functionalized, that have 6 to 120 carbon atoms and that bind to these amide units, and one or more fibers, said polymer being selected from polyamide between polymers of the following formula (I), and mixtures thereof: ** (See formula) ** wherein n represents 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, independently in each case, an alkyl or alkenyl group of at least 4 carbon atoms; R2 represents, independently in each case, a group based on C4 to C42 hydrocarbon, provided that 50% of the groups R2 represent a group based on C30 to C42 hydrocarbon; R3 represents, independently in each case, an organic group containing at least 2 carbon atoms, hydrogen atoms and possibly one or more oxygen or nitrogen atoms; and R4 represents, independently in each case, a hydrogen atom, a C1 to C10 alkyl group or a direct link to R3 or another R4, such that the nitrogen atom to which both R3 and R4 bind form part of a heterocyclic structure defined by R4-N-R3, at least 50% of the R4 groups representing a hydrogen atom. |
