Abstract

Cosmetic agents and methods for the temporary deformation of keratin-containing fibers using the cosmetic agents are provided herein. In one embodiment, the cosmetic agent for the temporary shaping of keratinic fibers includes a cosmetic preparation. The cosmetic preparation includes at least one copolymer a1), made up of at least the following monomer units: (meth)acrylic acid, (meth)acrylic acid alkyl ester, and (meth)acrylic acid hydroxyalkyl ester. The cosmetic preparation further includes at least one copolymer a2), made up of at least the following monomer units: N-tert-butylacrylamide, acrylic acid, and ethyl acrylate. The weight proportion of copolymers a1) and a2) in terms of the total weight of the cosmetic preparation is about 10 to about 30% by weight.

First claim
