Look what happens when ^ you combine silicate chemistry with an active imagination. Soluble silicates: Things your favorite soap opera never told you. The keys to any successful soap opera are bathos, conflict, suspense, and soluble silicates. Of these, soluble silicates are the most important. Without them there would be few detergents. Which means there would be few sponsors. General Hospital could be reduced to a clinic. Of course, to those of us in the chemical business, it comes as no surprise that soluble silicates are vital to detergent chemistry. They've been used as detergent and soap builders for over 100 years.

T1ÏII Early on, they were used to increase foam stability and decrease the formation of insoluble soaps in hard water. When synthetic detergents came along, soluble silicates became even more important: enhancing the performance of surfactants; providing corrosion

protection; and helping form a better spray- # dried particle. And when the phosphate crisis hit, \ hydrous sodium polysilicates were there to serve as partial or complete phosphate replacements. Bit of a switch. Much of the appeal of soluble silicates lies in their action as deflocculation and suspending agents. They break agglomerated solids into fine particles which remain in suspension until rinsed away.
