<p>Rinse-off hair care compositions consisting essentially of emulsions of water-insoluble adhesive polymers having a solubility in water at 25 °C less than 1.0 % for repairing split ends. Hair rinse compositions, in emulsion or dispersion form, which condition the hair and facilitate setting thereof, include a hair conditioning and emulsifying cationic compound, a water insoluble acrylic or acrylate polymer and a solvent which is a stabilizing and compatibilizing proportion of the composition comprising a higher aliphatic alcohol and/or alcohol ethoxylate, in an aqueous medium. The cationic compound is a quaternary ammonium salt preferably a higher alkyl trimethyl ammonium chloride and the polymer is preferably an acrylamide acrylate copolymer. Preferably, solvents in the compositions are C9-20 aliphatic alcohols and/or C9-20 alcohol ethoxylates having less than 2 ethoxy groups per mole. 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.</p> |
