摘要： A stable, aqueous cationic hydrogel of, by weight, 1-50% of a crosslinked cationic copolymer of 5-95% vinylpyrrolidone (VP) and 5-95% 3-dimethylaminopropyl(meth)acrylamide (DMAPMA) monomers, a crosslinking agent in an amount of 0.05-1% of said monomers, and water is described. The hydrogel has a pH of about 10 and a Brookfield viscosity of about 650 (Model DV-II+, RV spindle #3, speed 10 rpm); it can increase its viscosity by up to 40× at a pH of 3-9 and absorb up to 200× its weight of water. The hydrogel also can effectively condition hair even in the presence of an anionic surfactant.
