Abstract

Disclosed is a cosmetic product comprising a) a cosmetic preparation that has a viscosity of 5,000 to 1,000,000 mPas and contains, in relation to the total weight of the preparation, a1) 60 to 98 wt % of at least one polar solvent; a2) 0.01 to 10 wt % of at least one thickener; b) a device for flash evaporating cosmetic preparation a). Also disclosed are a method using corresponding products and the use of cosmetic preparation a) as a process material in a flash evaporation device.

First claim

What is claimed is:

1. A comprehensive product, comprising:
a) a cosmetic preparation with a viscosity from 5,000 to 1,000,000 mPas which includes, with respect to its total weight,
a1) 60 to 98 wt % of at least one polar solvent;
a2) 0.01 to 10 wt % of at least one thickener;

b) a device for flash-evaporating the cosmetic preparation a), wherein the flash-evaporating device comprises a container b1) a valve, and a heating device b2) and is configured such that
the cosmetic preparation can be received in the interior space of the container b1),
the interior of the container b1) filled at least in part with the cosmetic preparation a) can be sealed,
the cosmetic preparation a) in the closed interior of the container b1) is heated by means of the heating device b2) to a temperature of 140° C. and 160° C., thereby increasing the pressure,

the heated cosmetic preparation a) can be released from the interior of the container b1) under pressure reduction into the environment.

2. The cosmetic product as set forth in claim 1 , wherein the viscosity of the cosmetic preparation a) is 10,000 to 250,000 mPas.

3. The cosmetic product as set forth in claim 1 , wherein the viscosity of the cosmetic preparation a) is 20,000 to 250,000 mPas.

4. The cosmetic product as set forth in claim 1 , wherein the proportion by weight of the polar solvent a1) to the total weight of the cosmetic preparation a) is 70 to 98 wt %.

5. The cosmetic product as set forth in claim 1 , wherein the proportion by weight of the polar solvent a1) to the total weight of the cosmetic preparation a) is 80 to 95 wt %.

6. The cosmetic product as set forth in claim 1 , wherein the proportion by weight of the thickener a2) to the total weight of the cosmetic preparation a) is 0.05 to 8.0 wt %.

7. The cosmetic product as set forth in claim 1 , wherein the proportion by weight of the thickener a2) to the total weight of the cosmetic preparation a) is 0.1 to 5.0 wt %.

8. The cosmetic product as set forth in claim 1 , wherein the thickener a2) is a polymeric organic thickeners.

9. The cosmetic product as set forth in claim 1 , wherein the cosmetic preparation a) includes, with respect to its total weight, 0.1 to 20 wt % of a film-forming polymer a3).

10. The cosmetic product as set forth in claim 1 , wherein the cosmetic preparation a) includes, with respect to its total weight, 0.5 to 15 wt % of a film-forming polymer a3).

11. The cosmetic product as set forth in claim 1 , wherein the cosmetic preparation a) includes, with respect to its total weight, 1.0 to 10 wt % of a film-forming polymer a3).

12. A method for temporarily deforming keratin-containing fibers, comprising:
applying to keratin-containing fibers the cosmetic preparation of claim 1 using a flash evaporation device.
