Abstract:
The invention relates to cosmetic products containing, in a cosmetic carrier, a combination of (a) at least one polyamide that is a reaction product of at least one dimerized fatty acid and at least one diamino compound, and (b) at least one copolymer comprising at least one structural unit of formula (b-i) and at least one structural unit of formula (b-ii) wherein R is a linear or branched (C4 to C10) alkyl group, especially a branched (C4 to C10) alkyl group, and R′ is a hydrogen atom or a methyl group. The products are especially suitable for fixing a hairstyle. The combination of active ingredients provides the hairstyle with an excellent, flexible and long-lasting hold.
