Abstract

A cosmetic product for temporarily reshaping keratin-containing fibers, in particular human hair, containing, in a cosmetic carrier, in relation to its total weight,
a) from about 0.01 to about 10 wt. % of at least one (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer; b) from about 0.1 to about 10 wt. % of at least one non-ionic, anionic and/or amphoteric film-forming polymer,

use thereof, and method using this product.

First claim

The invention claimed is:

1. A cosmetic product for temporarily reshaping keratin-containing fibers comprising, in a cosmetic carrier, from about 0.01 to about 10 wt. % of a (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a), based on a total weight of the cosmetic product; and
from about 0.1 to about 10 wt. % of at least one non-ionic, anionic and/or amphoteric film-forming polymer b), wherein the at least one film-forming polymer comprises a vinylpyrrolidone/vinyl acetate copolymer.

2. The cosmetic product according to claim 1 , wherein the proportion by weight of the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a) in the total weight of the cosmetic product is from about 0.1 to about 3.0 wt. %, and
the proportion by weight of the vinylpyrrolidone/vinyl acetate copolymer is from about 0.3 to about 7.0 wt. %, based on the total weight of the cosmetic product.

3. The cosmetic product according to claim 1 , wherein the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer is a (meth)acrylamidopropyltrimethylammonium salt homopolymer, wherein the proportion by weight of the (meth)acrylamidopropyltrimethylammonium salt homopolymer is from about 0.1 to about 3.0 wt. %, and wherein the proportion by weight of the vinylpyrrolidone/vinyl acetate copolymer is from about 0.3 to about 7.0 wt. %, wherein the wt. % are based on the total weight of the cosmetic product.

4. The cosmetic product according to claim 1 , wherein:
the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a) is present in the cosmetic composition in an amount of from about 0.1 to about 3.0 wt. %, based on the total weight of the cosmetic composition; and
the proportion by weight of the film-forming polymer b) in the total weight of the cosmetic product is from about 0.3 to about 7.0 wt. %, based on the total weight of the cosmetic product, wherein the film-forming polymer b) comprises a non-ionic film forming polymer, wherein the non-ionic film forming polymer consists of the vinylpyrrolidone/vinyl acetate copolymer, and wherein the non-ionic film forming polymer is present in the cosmetic product at from about 0.3 to about 7.0 weight percent, based on the total weight of the cosmetic product.

5. The cosmetic product according to claim 4 , wherein the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a) consists of a (meth)acrylamidopropyltrimethylammonium salt homopolymer.

6. The cosmetic product according to claim 1 , wherein the cosmetic product comprises, in relation to its total weight, less than about 2.0 wt. % anionic and amphoteric surfactant.

7. The cosmetic product according to claim 1 , wherein the cosmetic product comprises, in relation to its total weight, from about 50 to about 99 wt. % of water or a water-alcohol mixture.

8. The cosmetic product according to claim 1 , wherein the cosmetic product comprises, in relation to its total weight, from about 1 to about 15 wt. % of at least one propellant.

9. A method for temporarily shaping keratin fibers, comprising:
applying a cosmetic product to the keratin fibers, wherein the cosmetic product comprises, in a cosmetic carrier:
from about 0.1 to about 3.0 wt. % of at least one (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a), based on a total weight of the cosmetic product; and
from about 0.3 to about 7.0 wt. % of at least one non-ionic, anionic and/or amphoteric film-forming polymer b), based on the total weight of the cosmetic product, and wherein the at least one film-forming polymer comprises a vinylpyrrolidone/vinyl acetate copolymer.

10. The cosmetic product according to claim 1 , wherein the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a) consists of (3-acrylamidopropyl)trimethylammonium salt homopolymer.

11. The cosmetic product according to claim 1 , wherein the proportion by weight of the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a), in relation to the total weight of the cosmetic product, is from about 0.05 to about 6.0 wt. %.

12. The cosmetic product according to claim 1 , wherein the proportion by weight of the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a), in relation to the total weight of the cosmetic product, is from about 0.1 to about 3.0 wt. %.

13. The cosmetic product according to claim 1 , wherein the proportion by weight of the film-forming polymer b) in the total weight of the cosmetic product is from about 0.25 to about 8.0 wt. %.

14. The cosmetic product according to claim 1 , wherein the proportion by weight of the film-forming polymer b) in the total weight of the cosmetic product is from about 0.3 to about 7.0 wt. %.

15. The cosmetic product according to claim 1 , wherein the cosmetic product also comprises, in relation to its total weight, from about 0.2 to about 5.0 wt. % of at least one cationic nourishing active agent different from the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a).

16. The cosmetic product according to claim 1 , wherein the cosmetic product also comprises, in relation to its total weight, from about 0.3 to about 4.0 wt. % of at least one cationic nourishing active agent different from the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a).

17. The cosmetic product according to claim 1 , wherein the cosmetic product also comprises, in relation to its total weight, from about 0.4 to about 3.0 wt. % of at least one cationic nourishing active agent different from the (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer a).

18. The cosmetic product according to claim 1 , wherein the cosmetic product comprises, in relation to its total weight, less than about 0.1 wt. %, anionic and amphoteric surfactant.

19. The cosmetic product according to claim 1 , wherein the cosmetic product comprises, in relation to its total weight, from about 60 to about 95 wt. % of water or a water-alcohol mixture.
