Abstract

Cosmetics, particularly styling agents, containing at least one copolymer A composed of at least one monomer A1 chosen from acrylic acid, methacrylic acid, alkyl acrylates, and alkyl methacrylates, and at least one amphoteric monomer A2 chosen from (meth)acryloyl alkyl betaines and (meth)acryloyl alkyl amine oxides, and at least one film-forming and/or stabilizing anionic copolymer B in a cosmetically acceptable carrier. Also disclosed is the use of said cosmetics for temporarily shaping hair.

Claims

1. A cosmetic agent comprising in a cosmetically acceptable carrier:

a) at least one copolymer A made up from

at least two monomers A1, wherein the first monomer is chosen from acrylic acid, methacrylic acid, acrylic acid methyl ester, methacrylic acid methyl ester, acrylic acid ethyl ester, methacrylic acid ethyl ester, acrylic acid propyl ester, methacrylic acid propyl ester, acrylic acid isopropyl ester and methacrylic acid isopropyl ester, and the second monomer is chosen from acrylic acid stearyl ester and methacrylic acid stearyl ester, and

at least one monomer A2 chosen from (meth)acryloyl alkylamine oxides of Formula A2-II

2. Method of styling hair comprising applying a cosmetic agent according claim 1 onto the hair by pump hair spray, aerosol hair spray, pump hair foam, aerosol hair foam or styling gel, and optionally working the agent into the hair with the palms of the hand and/or the fingers.

3. A cosmetic agent comprising in a cosmetically acceptable carrier:

a) at least one copolymer A made up from

at least two monomers A1, wherein the first monomer is chosen from acrylic acid, methacrylic acid, acrylic acid methyl ester, methacrylic acid methyl ester, acrylic acid ethyl ester, methacrylic acid ethyl ester, acrylic acid propyl ester, methacrylic acid propyl ester, acrylic acid isopropyl ester and methacrylic acid isopropyl ester, and the second monomer is chosen from acrylic acid stearyl ester and methacrylic acid stearyl ester, and

at least one monomer A2 chosen from (meth)acryloyl alkylamine oxides of Formula A2-II
