Abstract

A cosmetic agent for the temporary deformation of keratinous fibers and a method for the temporary deformation of keratinous fibers using the cosmetic agent are provided. The cosmetic agent comprises:
a) a cosmetic preparation containing
a1) at least one copolymer composed at least of the following monomer units:
styrene acrylic acid and/or methacrylic acid;
a2) at least one copolymer composed at least of the following monomer units:
N-tert-butylacrylamide acrylic acid ethyl acrylate,

wherein the weight fraction of copolymers a1) and a2) in the total weight of the cosmetic preparationis about 1.0 to about 10% by weight.

First claim

The invention claimed is:

1. A cosmetic agent for the temporary deformation of keratinous fibers, comprising:
a) a cosmetic preparation comprising:
a1) at least one copolymer composed at least of the following monomer units:
styrene
acrylic acid and/or methacrylic acid; and

a2) at least one copolymer composed at least of the following monomer units:
N-tert-butylacrylamide
acrylic acid
ethyl acrylate,

wherein the weight fraction of copolymers a1) and a2) in the total weight of the cosmetic preparation is about 1.0 to about 10% by weight; and
wherein the weight ratio of copolymer a1) to copolymer a2) is about 1:1 to about 3:1.

2. The cosmetic agent according to claim 1 , wherein the weight fraction of copolymers a1) and a2) in the total weight of the cosmetic preparation is about 1.5 to about 9.0% by weight, respectively.

3. The cosmetic agent according to claim 2 , wherein the weight fraction of copolymers a1) and a2) in the total weight of the cosmetic preparation is about 2.0 to about 8.0% by weight, respectively.

4. The cosmetic agent according to claim 1 , wherein the cosmetic preparation, based on its total weight, contains about 0.1 to about 9.9% by weight of copolymer a 1).

5. The cosmetic agent according to claim 4 , wherein the cosmetic preparation, based on its total weight, contains about 0.5 to about 8.5% by weight of copolymer a 1).

6. The cosmetic agent according to claim 5 , wherein the cosmetic preparation, based on its total weight, contains about 1.0 to about 7.0% by weight of copolymer a 1).

7. The cosmetic agent according to claim 1 , wherein the cosmetic preparation, based on its total weight, contains about 0.1 to about 9.9% by weight of copolymer a2).

8. The cosmetic agent according to claim 7 , wherein the cosmetic preparation, based on its total weight, contains about 0.5 to about 8.5% by weight of copolymer a2).

9. The cosmetic agent according to claim 8 , wherein the cosmetic preparation, based on its total weight, contains about 1.0 to about 7.0% by weight of copolymer a2).

10. The cosmetic agent according to claim 1 , wherein the agent also comprises:
b) at least one propellant.

11. The cosmetic agent according to claim 1 , wherein the cosmetic preparation, based on its total weight contains about 40 to about 98% by weight of polar solvent.

12. The cosmetic agent according to claim 1 , wherein the cosmetic preparation further comprises a polymeric organic thickener.

13. A cosmetic product comprising:
i) a cosmetic agent comprising:
a) a cosmetic preparation comprising:
a1) at least one copolymer composed at least of the following monomer units:
styrene
acrylic acid and/or methacrylic acid; and

a2) at least one copolymer composed at least of the following monomer units:
N-tert-butylacrylamide
acrylic acid
ethyl acrylate,

wherein the weight fraction of copolymers a1) and a2) in the total weight of the cosmetic preparation is about 1.0 to about 10% by weight; and
wherein the weight ratio of copolymer a1) to copolymer a2) is about 1:1 to about 3:1; and

ii) a dispensing device having a spray valve.

14. The cosmetic agent according to claim 13 , wherein the cosmetic preparation, based on its total weight, contains about 0.1 to about 9.9% by weight of copolymer a 1).

15. The cosmetic agent according to claim 13 , wherein the cosmetic preparation, based on its total weight, contains about 0.1 to about 9.9% by weight of copolymer a2).

16. A method for the temporary deformation of keratin-containing fibers, in particular human hair, in which the keratinous fibers are acted on by a cosmetic agent and temporarily fixed in shape, the cosmetic agent comprising:
a) a cosmetic preparation comprising:
a1) at least one copolymer composed at least of the following monomer units:
styrene
acrylic acid and/or methacrylic acid; and

a2) at least one copolymer composed at least of the following monomer units:
N-tert-butylacrylamide
acrylic acid
ethyl acrylate,

wherein the weight fraction of copolymers a1) and a2) in the total weight of the cosmetic preparation is about 1.0 to about 10% by weight; and
wherein the weight ratio of copolymer a1) to copolymer a2) is about 1:1 to about 3:1.
