Potassium Silicates are recommended for liquid and paste soaps. They increase the scudding ability of these soaps, effectively suspend soil and prevent the redeposition of removed soil. Potassium Silicates offer the advantages of high solubility and miscibility.

Similarly, synthetic anionic or non-ionic detergents may be built into heavy-duty liquid household or industrial laundry and cleaning formulations, using Potassium for greater solubility and compatibility with polyphosphate.
