Abstract
Abstract The preparation and applications of anionic siliconate-zeolite composites are disclosed. The composites are formed by coating the surface of zeolite particles with an aqueous solution of an anionic functional organosiliconate. The composites are particularly useful as components of soluble silicate containing detergent compositions since they do not agglomerate with the soluble silicates to form large insoluble particulates that can deposit on fabrics during laundry. Detergent compositions containing the composites are disclosed.
