Claims23
A sulfate-free cosmetic rinse-off composition comprising:
- (a) a hyperbranched copolymer;
- (b) at least one cationic polymer having quaternary ammonium groups, and
- (c) an amphoteric surfactant which is acyl glutamate having an acyl group which comprises from 8 to 19 carbon atoms, wherein
- the hyperbranched copolymer is a copolymerization reaction product of the monomers:
- (i) dodecenyl succinic acid anhydride,
- (ii) diisopropanol amine, and
- (iii) bis-dimethylaminopropyl amine, and wherein
- the hyperbranched copolymer has terminal groups of the formula
- and has a molecular weight Mn of between 1200 and 4000 g/mol;
- and wherein
- the sulfate-free cosmetic rinse-off composition comprises less than 0.5% by weight, relative to the weight of the composition, of any anionic surfactant having a terminal anionic group of the formula
