In one embodiment of the composition, the polyurethane is thermoplastic for coating or molding applications. In another embodiment, the composition is a polyurethane foam particularly useful as a sponge for scrubbing which provides almost instantaneous release of the complex. The sponge may be provided in a package which includes other items useful for scrubbing.
