Abstract

Cosmetic agents and methods for temporarily shaping keratin-containing fibers using the cosmetic agents are provided herein. In one embodiment, the cosmetic agent includes a cosmetic carrier. The cosmetic agent further includes at least one chitosan or derivative thereof. The cosmetic agent further includes at least one hydrophobic pyrogenic silicic acid. The cosmetic agent also includes at least one non-ionic, anionic, or amphoteric film-forming polymer. In another embodiment, the method includes the step of using the cosmetic agent for temporarily shaping keratin-containing fibers.

First claim

The invention claimed is:

1. A cosmetic agent for temporarily shaping keratin-containing fibers, comprising:
a cosmetic carrier;
at least one chitosan or derivative thereof in an amount of from about 0.2 to about 1 wt. % based on the total weight of the cosmetic agent, the at least one chitosan or derivative thereof comprising an at least partially deacetylated chitosan;
at least one hydrophobic pyrogenic silicic acid in an amount of from about 0.2 to 1 wt. % based on the total weight of the cosmetic agent, the at least one hydrophobic pyrogenic silicic acid modified at the surface with hydrophobic groups comprising alkyl groups; and
at least one non-ionic film-forming polymer in an amount of from about 2 to about 7 wt. % based on the total weight of the cosmetic agent, the at least one non-ionic film-forming polymer comprising at least one homopolymer or copolymer of vinylpyrrolidone.

2. The cosmetic agent according to claim 1 , wherein at least one neutralization product of chitosan with at least one acid is contained as a chitosan or derivative thereof.

3. The cosmetic agent according to claim 2 , wherein the acid is selected from inorganic acids, organic carboxylic acids, or mixtures of these acids.

4. The cosmetic agent according to claim 1 , wherein the at least one hydrophobic pyrogenic silicic acid comprises a compound known under the INCI name Silica Dimethyl Silylate.

5. The cosmetic agent according to claim 1 , wherein the cosmetic agent additionally comprises at least one surfactant.

6. The cosmetic agent according to claim 1 , wherein the cosmetic agent additionally comprises at least one non-ionic emulsifier.

7. The cosmetic agent according to claim 1 , wherein the cosmetic agent comprises water and/or a water-alcohol mixture.

8. The cosmetic agent according to claim 1 , wherein the cosmetic agent comprises at least one propellant.

9. The cosmetic agent according to claim 3 , wherein the inorganic acid comprises hydrochloric acid.

10. The cosmetic agent according to claim 3 , wherein the organic carboxylic acid comprises lactic acid, formic acid, pyrrolidone carboxylic acid, nicotinic acid, hydroxyisobutyric acid, hydroxyisovaleric acid, or mixtures of these acids.

11. The cosmetic agent according to claim 6 , wherein the at least one non-ionic emulsifier comprises at least one PEG derivative of hydrogenated castor oil.

12. The cosmetic agent according to claim 8 , wherein the at least one propellant comprises propane and/or butane.

13. A method for temporarily shaping keratin-containing fibers, the method comprising the step of using a cosmetic agent according to claim 1 .
