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. This method is subject to certain disadvantages, among which are the tiresome and time-consuming repetitive step of first supplying the applicator with a quantity of the composition, the difficulty of controlling the amount of composition so applied to the skin, the tendency to permanently or temporarily misplace the container holding the composition, and the like.
