This disclosure teaches synthetic polyurethane sponges manufactured with at least 4% of one or more additives dispersed therein. The additives may be soap, lotions, detergents, pesticides, lanolin, scouring particles, silicone oils, bath oils, or the like or combinations thereof. The sponges\skeletons are developed by reaction of a polyether or a polyester with a suitable isocyanate in the presence of a catalyst with the additives entrapped in voids of the sponges. An additive bearing material, i.e. a carrier material containing the additive is prepared. The carrier material is then mixed into a foam forming reaction mass. By this expedient the additive does not impair desired foam formation. The sponges are provided with high liquid absorbency and fine “hand”by virtue of manufacturing methods and specific catalysts employed.

A resilient polyurethane foam sponge product comprising an amount of a lotion of at least 4 percent by weight of the product sponge dispersed uniformly within the cellular structure of the synthetic polyurethane sponge, said sponge product produced by reaction of a component selected from the group consisting of polyesters and polyethers with an organic polyisocyanate in the presence of a catalyst to obtain a foam forming mass, the lotion being dispersed in the reaction mass prior to the onset of foam formation. A resilient polurethane foam sponge product comprising an amount of a pesticide of at least 4 percent by weight of the product sponge dispersed uniformly within the cellular structure of the synthetic polyurethane sponge, said sponge product produced by reaction of a component selected from the group consisting of polyesters and polyethers with an organic polyisocyanate in the presence of a catalyst to obtain a foam forming mass, the pesticide being dispersed in the reaction mass prior to the onset of foam formation.
