Abstract
Abstract A hair treatment composition is provided that includes a water-insoluble, dispersible polymeric resin having a viscosity of less than 2 centipoise at 25° C. when dispersed at 10% in water; a water-soluble polymeric resin having a viscosity greater than 6 centipoise at 25° C. when 10% is placed in water; and a water-soluble polymer of molecular weight greater than about 500,000. Illustrative of the water-insoluble resin is a diglycol/cyclohexanedimethanol/isophthalates/sulfoisophthalates polyester. Preferably the water-soluble polymeric resin is a copolymer of polyvinyl-pyrrolidone and vinyl acetate. The preferred water-soluble polymer is polyvinylpyrrolidone, especially a polymer having molecular weight of around 630,000.
