Abstract: This invention relates to the deposition of particulate benefit agents onto keratin-containing substrates such that the deposited particulates are resistant to removal by exposure to surfactants or cleansing agents. The deposition is accomplished by sequentially treating the substrate with a cationic composition followed by treatment with an anionic particulate benefit agent.

Abstract: This invention relates to compositions and methods for providing cosmetic and other potential benefits to keratin-containing substrates.

Abstract: 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.
