Claims22
1-12. (canceled)
A personal care composition comprising:
- i) from about 0.2 to about 10% by weight of a thickening agent comprising a crosslinked alkali swellable polyacrylate prepared by polymerizing a formulation comprising:
- a) from about 20 to about 70% by weight of a monoethylenically unsaturated monomer containing a carboxylic group;
- b) from about 20 to about 70% by weight of a (meth)acrylic acid ester;
- c) from about 0.05 to about 3% by weight of an unsaturated monomer containing one or more acetoacetyl or cyanoacetyl groups;
- d) from about 0.01 to about 3% by weight of a polyethylenically unsaturated monomer;
- and
- e) from about 0 to about 10% by weight of a nonionic acrylic associative monomer;
- and
- ii) from about 0.1 to about 60% by weight of a surfactant selected from the group consisting of anionic surfactants, amphoteric surfactants, cationic surfactants, zwitterionic surfactants, non-ionic surfactants, and mixture thereof.
