Spongetech has solved this problem. Everyone should take a minute to look how this foam is created.

Hydrophilic Foam.

" The polyurethane prepolymer is foamed in the presence of an aqueous component, preferably water, in the conventional manner known in the art. The aqueous component may also be a water slurry or suspension, a water emulsion, or a water solution having water soluble materials disposed therein. The reaction mixture which contains at least the polyurethane prepolymer, and a quaternary ammonium compound having germicidal properties. The reaction mixture typically contains further constituents which take part in reaction whereby the polyurethane foams which exhibit an antimicrobial benefit are formed. During the reaction wherein the polyurethane foam is formed, the amount of water present in the reaction mixture reacts with the free isocyanate groups to release carbon dioxide, which blows the polyurethane prepolymer into a cross-linked, open-celled foam which is rendered hydrophilic by the integral entrapment of excess water in the cell walls of the foam matrix. When the reaction mixture is allowed to set in molds, a flexible, resilient foam body of the desired shape is formed. Alternately the reaction mixture may be applied to a substrate such as sheet, plate, film but especially a silicone coated release sheet and allowed to set, which may provide a flexible resilient foam body in a generally planar or sheet form. "


The beauty to Spongetech's product is simple. The sponge is made with two parts, polyurethane prepolymer and water.(or anything waterbased)When the water interacts with the prepolymer, CO2 gas is released as a bi product of the reaction. That CO2 released is what gives the sponge the volume as it expands the mixture. After the reaction is complete, all water is turned into CO2 and all that is left is polyurethane and the water soluble ingredients. Only the water reacts and all other water based chemicals are left behind, and remain in the foam, they market this as the "soap infusion process". The sponge literally is soap! That is why it is the smarter sponge, and given enough time and marketing this product will replace every single cleaning sponge in homes all over the world.
