Abstract
Abstract Hair rinse compositions, in stable emulsion or dispersion form, which condition the hair and facilitates setting thereof, includes a hair conditioning and emulsifying cationic compound, a water insoluble acrylic or acrylate polymer and a higher aliphatic alcohol, in an aqueous medium. The cationic compound is a quarternary ammonium salt preferably a higher alkyl trimethyl ammonium chloride, the polymer is preferably an acrylamide acrylate copolymer and the higher alcohol is preferably a C₉₋₁₃ alkanol. The preferred emulsion, which is normally of the oil-in-water type, preferably includes propylene glycol and a nonionic surfactant, and the aqueous medium is preferably water, or is essentially water. The invention also includes processes for making and using the invented hair rinse compositions.
