Abstract: A hydrophilic open-celled poly (urea/urethane) sponge derived from a prepolymer produced by the reaction of a polyoxyalkylene polyol with a stoichiometric excess of an organic polysocyanate, said sponge containing substantially uniformly distributed throughout the pores thereof a readily releasable skin care composition and methods of making same and using same for treating skin.It has of course long been known to treat the skin for various purposes by applying thereto a skin care composition, such application being commonly effected by first impregnating an absorbent fibrous pad or sponge applicator with the composition, or supplying a quantity of such composition to the surface of the pad or sponge applicator, and then transferring said composition to the skin by wiping and rubbing same with the applicator.

Abstract: A hydrophilic flexible open-celled poly (urea/urethane) sponge derived from prepolymer produced by reaction of a polyoxyalkylene polyol with a stoichiometric excess of an organic polyisocyanate, said sponge containing uniformly distributed therethrough a readily releasable wax composition, and methods of making and using same for waxing surfaces.
