Abstract
Abstract An aqueous hair treatment composition is provided that includes a water-soluble polymer having a solution viscosity at 10% in water of less than about 20,000 cps at 25° C., and a latex of water-insoluble polymeric particles dispersed in water and having a glass transition temperature between 250 and 300° K., the average particle size being no higher than about 3 microns. Preferably the latex particles are formed from respective monomers by emulsion polymerization.
