printmail01,
I wasn't gonna write anything, but you know that hydrophilic sponges are not exactly a new invention, neither are soap filled sponges new, I wonder why H.H. Browns patents were even allowed:


Patent #3,508,953 Apr. 28 1970 talks about rendering Polyurethane sponges hydrophilic.

Patent #4,271,272 Jun. 2, 1981 claims:

1. 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.

2. The product of claim 1 wherein the lotion is a silicone-containing material.

3. The product of claim 2 wherein the silicone-containing material comprises between 10 and 20 percent by weight of the product sponge.

4. 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.

5. A resilient polyurethane foam sponge product comprising an amount of a bath oil 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 bath oil being dispersed in the reaction mass prior to the onset of foam formation.

6. The product of claim 5 wherein the bath oil is selected from the group consisting of acetylated lanolin, acetylated lanolin alcohol, isopropyl myristate, mineral oil and compatible combinations of same.

7. The product of claim 1, 4 or 5 wherein the additives of said claims are first distributed within a dry, vehicular material before incorporation into the reaction mass, the vehicular material being soap.

There is a lot more of course.

Now this I find interesting... what happened last time somebody used the "SPNG is screwed because Dicon has licensed their patent to somebody else" bullet point to scare people?

SPNG buys out Dicon.

Hmm.. can we go 2 for 2?
