Abstract

A cosmetic composition for the temporary shaping of keratinic fibers, containing:

• • a) at least one non-crosslinked, hydrophobically modified (meth)acrylic acid copolymer
  • b) at least one, at least partially imidized maleic anhydride copolymer,
    its use and method using such a composition.

Claims

1. A cosmetic composition for the temporary shaping of keratinic fibers, comprising:

a) at least one non-crosslinked, hydrophobically modified (meth)acrylic acid copolymer a), wherein the copolymer a) has the INCI name Acrylates/C10-30 Alkyl Methacrylate Copolymer; and

b) at least one, at least partially imidized maleic anhydride copolymer b), wherein the copolymer b) has the INCI name Isobutylene/Ethylmaleimide/Hydroxyethyl Maleimide Copolymer;

wherein the proportions of each of copolymers a) and b) are about 0.5% by weight of the total composition.

2. The cosmetic composition according to claim 1, wherein the cosmetic composition further comprises

c) polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer.

3. The cosmetic composition according to claim 2, wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 0.1 to about 10% by weight.

4. The cosmetic composition according to claim 2, wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 0.2 to about 8.5% by weight.

5. The cosmetic composition according to claim 2, wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 3.0 to about 7.0% by weight.

6. The cosmetic composition according to claim 1, wherein the composition comprises, based on its total weight, at least about 20% by weight of water.

7. The cosmetic composition according to claim 1 further comprising polyvinylpyrrolidone.

8. The cosmetic composition according to claim 1, wherein the composition comprises, based on its total weight, at least about 40% by weight of water.

9. The cosmetic composition according to claim 1, wherein the composition comprises, based on its total weight, at least about 70% by weight of water.

10. A method for the temporary deformation of keratin-containing fibers, in which the keratinic fibers are acted upon by a cosmetic composition according to claim 1 and temporarily fixed in their shape.
