Abstract

Cosmetic products and methods for temporarily shaping keratin-containing fibers using the cosmetic products are provided herein. A cosmetic product for temporarily shaping keratinic fibers includes a cosmetic preparation. The cosmetic preparation contains at least one copolymer a1) that is constructed from at least the following monomer units: (meth)acrylic acid, (meth)acrylic acid alkyl ester, and (meth)acrylic acid hydroxy alkyl ester. The cosmetic preparation further contains at least one copolymer a2) that is constructed from at least the following monomer units: styrene, and at least one of acrylic acid or methacrylic acid. The proportion by weight of copolymers a1) and a2) with respect to the total weight of the cosmetic preparation is about 1.0 to about 10 wt %.

at least one copolymer a2) that is constructed from at least 90 wt % of the following monomer units based on the total weight of the copolymer a2);
styrene,
at least one of acrylic acid and/or methacrylic acid; and
acrylic acid ester and/or methacrylic acid ester;

wherein the proportion by weight of copolymers a1) and a2) with respect to the total weight of the cosmetic preparation is about 1.0 to about 10 wt %; and
wherein the weight ratio of copolymer a1) to copolymer a2) is from about 1:3 to about 3:1.

2. The cosmetic product as set forth in claim 1 , wherein the proportion by weight of copolymers a1) and a2) with respect to the total weight of the cosmetic preparation is about 1.5 and about 9.0 wt %.

3. The cosmetic product as set forth in claim 1 , wherein the preparation contains, with respect to its total weight, about 0.1 to about 9.9 wt % of copolymer a1).

4. The cosmetic product as set forth in claim 1 , wherein the preparation contains, with respect to its total weight, about 0.1 to about 9.9 wt % of copolymer a2).

5. The cosmetic product as set forth in claim 1 , wherein the weight ratio of copolymer a1) to copolymer a2) is from about 1:7 to about 7:1.

6. The cosmetic product as set forth in claim 1 , wherein the product further comprises at least one propellant.

7. A comprehensive product, comprising:
a cosmetic product as set forth in claim 1 ; and
a dispensing device with spray valve.

8. The cosmetic product as set forth in claim 1 , wherein the proportion by weight of copolymers a1) and a2) with respect to the total weight of the cosmetic preparation is about 2.0 and about 8.0 wt %.

9. The cosmetic product as set forth in claim 1 , wherein the preparation contains, with respect to its total weight, about 0.5 to about 8.5 wt % of copolymer a1).

10. The cosmetic product as set forth in claim 1 , wherein the preparation contains, with respect to its total weight, about 1.0 to about 7.0 wt % of copolymer a1).

11. The cosmetic product as set forth in claim 1 , wherein the preparation contains, with respect to its total weight, about 0.5 to about 8.5 wt % of copolymer a2).

12. The cosmetic product as set forth in claim 1 , wherein the preparation contains, with respect to its total weight, about 1.0 to about 7.0 wt % of copolymer a2).
