<p>PROBLEM TO BE SOLVED: To provide a detergent-containing sponge eliminating the need for preparing a detergent when using a sponge, and being usable many times to provide a full washing effect. SOLUTION: This detergent-containing sponge 10 is obtained by adding water of 40 to 150 pts.wt. and either or both of a surfactant and soap of 0.05 to 150 pts.wt. to a prepolymer of 100 pts.wt. and reacting them together, the prepolymer being adjusted to NCO% of 3 to 20 wt.% by reacting a polyether polyol with an aromatic isocyanate, the polyether polyol having 2 to 6 functional groups, a polyoxyethylenic group of 15 to 100 wt.%, and a number average molecular weight of 600 to 4000.</p> |
