What is described herein are conditioning/styling tetrapolymers of vinyl caprolactam (VCL), vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and C-Calkyl quaternized dimethylaminopropyl (meth)acrylamide or methacrylic acid quaternized monomers (QDMAPMA), in a defined compositional range. Hair and skin care compositions which include these tetrapolymers exhibit advantageous low tackiness and high humidity resistance.

Conditioning/styling tetrapolymers

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&plus;, RV spindle &num;3, speed 10 rpm); it can increase its viscosity by up to 40&times; at a pH of 3-9 and absorb up to 200&times; its weight of water. The hydrogel also can effectively condition hair even in the presence of an anionic surfactant.

Stable, aqueous cationic hydrogel

A method of protecting hair or wool against thermal degradation when heat treated at 100-180&deg; C. which comprises applying a composition which includes methyl vinyl ether-maleic acid copolymer as an active constituent to said hair or wool.

Photostable UV absorbent containing A-cyano cinnamyl moiety

A system and method for measuring streaming potential, conductivity and permeability of a porous sample, such as a plug of fibrous material, in which a test electrolytic solution, such as a neutral dilute salt solution, is flowed through a flow cell containing the sample. The test solution, and a treatment solution whose effect on the sample is to be measured, are flowed through the flow cell as a series of liquid spurts. The system includes a plurality of solenoid valves which are controlled by a computer in accordance with a software program.
