ABSTRACT:
Personal care compositions are provided which have as a thickening agent a lightly cross-linked cationic vinyl addition polymer. Such compositions include water, at least one cosmetically-active agent, and such thickening agent, preferably one derived from the polymerization of a cationic vinyl addition monomer, acrylamide, and a small amount of a difunctional vinyl addition monomer for cross-linking purposes. Alternatively, the cross-linking functionality can be provided by the incorporation of an anionic vinyl addition monomer into the polymer.
