Abstract

The present invention relates to care agents comprising ethylene copolymers and to the use of the care agents or of the ethylene copolymers for improving the wet combability of hair and for achieving a waxy, groomed, soft feel to the hair.

First claim

1 . A care agent, wherein the care agent is a skincare composition or a haircare composition comprising
A) an ethylene copolymer comprising, in copolymerized form, a) 95 to 50% by weight of ethylene, b) 5 to 50% by weight of at least one monomer of the general formula (I) or of the general formula (Ia),

where
R 14 and R 15 are each independently selected from the group consisting of hydrogen, linear or branched C 1 -C 8 -alkyl, methoxy, ethoxy, 2-hydroxyethoxy, 2-methoxyethoxy and 2-ethoxyethyl,
R 17 is hydrogen or methyl,
R 18 is alkylene or hydroxyalkylene having 1 to 24 carbon atoms, optionally substituted by alkyl,
g is 0 or 1,
Z is nitrogen if g=1, or is oxygen if g=0,
R 25 and R 26 are each independently selected from the group consisting of hydrogen, linear or branched C 1 -C 40 -alkyl, formyl, linear or branched C 1 -C 10 -acyl, N,N-dimethylaminoethyl, 2-hydroxyethyl, 2-methoxyethyl, 2-ethoxyethyl, hydroxypropyl, methoxypropyl, ethoxypropyl and benzyl,
R 27 is selected from the group consisting of hydrogen, C 1 -C 40 linear or branched alkyl, formyl, C 1 -C 10 linear or branched acyl, N,N-dimethylaminoethyl, 2-hydroxyethyl, 2-methoxyethyl, 2-ethoxyethyl, hydroxypropyl, methoxypropyl, ethoxypropyl and benzyl,
Y − is an anion of an inorganic or organic acid,
c) 0 to 30% by weight of further monomers,
where the sum of a), b) and c) is 100% by weight, and
B) further conventional ingredients in care agents.

2 . The care agent according to claim 1 , wherein the ethylene copolymer comprises, in copolymerized form,
a) 80 to 60% by weight of ethylene, b) 20 to 40% by weight of at least one monomer of the general formula (I) or (Ia) c) 0 to 20% by weight of further monomers.

3 . The care agent according to claim 1 ,
wherein b) comprises N,N-dimethylaminoethyl methacrylate.

4 . The care agent according to claim 1 ,
wherein the ethylene copolymer is at least partially protonated.

5 . The care agent according to claim 1 , wherein, if the at least one monomer is of the general formula (Ia), then R 27 is hydrogen.

6 . The care agent according to claim 1 , wherein the care agent is a rinse off care agent.

7 . The care agent according to claim 6 , wherein the care agent is a haircare composition, comprising
A) the ethylene copolymer in an amount of 0.1 to 5% by weight, and B) further conventional ingredients in a haircare composition.

8 . The care agent according to claim 7 , wherein the care agent is a shampoo further comprising
C) anionic surfactants in an amount from 5 to 20% by weight.

9 . The care agent according to claim 8 , comprising
lauryl ether sulfate in an amount from 5 to 15% by weight.

10 . The care agent according to claim 9 , comprising
cocamidopropyl betaine in an amount from 1 to 5% by weight.

11 . A method for improving the wet combability of hair comprising applying a care agent according to claim 1 to the hair.

12 . A method for achieving a waxy, groomed, soft feel to hair, comprising applying a care agent of claim 1 to the hair.

13 . The care agent of claim 1 wherein the hair care composition is a shampoo.

14 . The care agent of claim 1 wherein R 18 is substituted by an alkyl group selected from the group consisting of C 2 H 4 , C 3 H 6 , C 4 H 8 , and CH 2 —CH(OH)—CH 2 , and R 27 is methyl or ethyl.

15 . The care agent according to claim 2 , wherein the ethylene copolymer comprises, in copolymerized form,
a) 70 to 60% by weight, of ethylene, b) 30 to 40 of at least one monomer of the general formula (I) and (Ia), and c) 0 to 10% by weight, of further monomers.

16 . The care agent according to claim 7 , comprising
A) the ethylene copolymer in an amount of 0.3 to 3%, by weight.

17 . The care agent according to claim 16 , comprising
A) the ethylene copolymer in an amount of 0.5 to 2%, by weight.

18 . The care agent according to claim 8 , comprising
C) anionic surfactant in an amount of 8 to 15%, by weight.

19 . The care agent according to claim 9 comprising lauryl ether sulfate in an amount of 8 to 13%, by weight.

20 . The care agent according to claim 10 comprising cocamidopropyl betaine in an amount of 2 to 4%, by weight.
