Hair treatment compositions containing itaconic acid mono-ester/acrylate copolymer and polystyrene sulfonate

摘要

The hair treatment composition contains a combination of at least one itaconic acid monoester/acrylate copolymer and at least one polystyrene sulfonate with a molecular weight in a range from 50,000 to 200,000. The itaconic acid monoester monomer or monomers are of formula CH₂═C(COOR¹)CH₂COOR², wherein one of R¹ and R² represents hydrogen and another of R¹ and R² represents —(CH₂CH₂O)_x—R³, x is a number between 1 and 100 and R³ is an alkyl group with 8 to 30 carbon atoms. In an especially preferred embodiment the hair treatment composition contains an itaconic acid monocetyl ester/acrylate copolymer and an itaconic acid monostearyl ester/acrylate copolymer.
