Abstract

Agents for treating fibers containing keratin containing in a cosmetically acceptable carrier (a) at least one cross-linked, amphiphilic, anionic polymer, comprising at least one structural unit of formula (I) and at least one structural unit of formula (II); and (b) at least one non-cross-linked, amphiphilic, anionic polymer, comprising at least one structural unit of the formula (III) and at least one structural unit of the formula (IV), said agents being suitable for temporarily deforming hair and for conditioning hair, in particular in the form of a hair cream or a hair gel.

Claims

1. Agent for treating keratin-containing fibers, especially human hair, comprising in a cosmetically acceptable carrier:

(a) at least one crosslinked amphiphilic, anionic polymer having at least one structural unit of Formula (I) and at least one structural unit of Formula (II),

2. Agent according to claim 1, wherein A¹ in Formula (II) is *—

(CH₂CH₂O)_x—

* wherein x is a whole number from 5 to 35.

3. Agent according to claim 1, wherein R² in Formula (II) is a methyl group.

4. Agent according to claim 1, wherein A² in Formula (IV) is *—

(CH₂CH₂O)_x—

* wherein x is a whole number from 5 to 35.

5. Agent according to claim 1, wherein R⁵ in Formula (IV) is a hydrogen atom.

6. Agent according to claim 1, wherein the crosslinked, amphiphilic, anionic polymer additionally comprises at least one structural unit of Formula (V),

7. Agent according to claim 1 wherein the crosslinked, amphiphilic, anionic polymers (a) are present in an amount of 0.1 wt. % to 5.0 wt. %, based on total weight of the agent.

8. Agent according to claim 1 wherein the uncrosslinked, amphiphilic, anionic polymers (b) is present in an amount of 0.1 wt. % to 5.0 wt. %, based on total weight of the agent.

9. Agent according to claim 1 wherein the crosslinked, amphiphilic, anionic polymers (a) and the uncrosslinked, amphiphilic, anionic polymers (b) are present in a weight ratio of 1 to 5 to 1.

10. Agent according to claim 1 further comprising a film-forming and/or setting polymer.

11. Agent according to claim 10, wherein the film-forming and/or setting polymer is chosen from at least one cationic polymer having at least one structural unit according to Formula (M11-a) and at least one structural unit according to Formula (M6) and at least one structural unit according to Formula (M10) and at least one structural unit according to Formula (M12)

12. Agent according to claim 10, wherein the film-forming and/or setting polymer is present in an amount of 0.01 wt. % to 20 wt. %, based on total weight of the agent.

13. Agent according to claim 1 further comprising at least one alkanolamine.

14. Method for treating keratin-containing fibers comprising applying an agent according to claim 1 onto the keratin-containing fibers.
