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.
Claims3
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
- wherein in Formula A2-II R1 is H or CH3, R2 and R3 are independently an optionally branched C1-C10 alkyl, and n is a whole number from 1 to 20, and wherein the copolymer A is selected from Acrylates/Stearyl Acrylate/Ethylamine Oxide Methacrylate Copolymer present in 28 to 32 wt. % of solids in ethanol, and
- b) a methacrylic acid/ethyl acrylate film-forming and/or setting anionic polymer B, and wherein copolymer A and the film forming and/or setting anionic polymer B are present in a weight ratio of about 1:1, and wherein the copolymer A is present in an amount of about 1 to about 12 wt. %, based on total weight of the agent, and the film forming and/or setting anionic polymer B is present in an amount of about 1 to about 10 wt. %, based on total weight of the agent.
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
- wherein in Formula A2-II R1 is H or CH3, R2 and R3 are independently an optionally branched C1-C10 alkyl, and n is a whole number from 1 to 20, and wherein the copolymer A is selected from Acrylates/Stearyl Acrylate/Ethylamine Oxide Methacrylate Copolymer present in 28 to 32 wt. % of solids in ethanol, and
- b) a methacrylic acid/ethyl acrylate film-forming and/or setting anionic polymer B, wherein copolymer A is present in an amount of about 2.5 wt. %, based on total weight of the agent, and the film forming and/or setting anionic polymer B is present in an amount of about 2.5 wt. %, based on the total weight of the agent, and wherein copolymer A and the film forming and/or setting anionic polymer B are present in a weight ratio of about 1:1.
