Polyquaternium 7 is a highly charged cationic copolymer of diallyl dimethyl ammonium chloride and acrylamide. It is used extensively for cosmetic applications. It is an invaluable multifunctional component in cosmetics and toiletries, and thus is one of the most widely produced cationic polymers in the world today.
Polyquaternium 7 is a unique copolymer especially developed for improved compatibility and clarity in anionic surfactant systems.
In shampoo, it increases and stabilizes foam, increases viscosity while contributing excellent lubricity, wet combability, and luster to hair reduces frizzies, without any build-up.
In skin care, it provides lubricity and substantive film forming properties, and helps disperse other functional ingredients on the skin.
Applications: Hair care, skin care, shave cream, liquid and bar soaps, bath products, lip care and deodorants.

I bought it for the first time to try in my hair conditioner formulation. It has a strong fish-like odour (not faint odour as in description). I cover it up with the other ingredients and fragrance.
