Abstract

A disposable washcloth, in one embodiment, is formed by impregnating a sheet of non-woven paper with a cured formulation of water activated polyurethane gel, a sudsing detergent, and an aqueous solution of a medicated cleansing agent, and in another embodiment is made by bonding a sheet of non-woven paper to a sheet of non-woven fabric composed of randomly oriented spray bonded synthetic fibers with the above-mentioned cured formulation. In both cases, the polyurethane dissolves at a slow rate when wetted and controllably releases the detergent and the cleansing agent with modest sudsing.
