  • Process for agglomerating aluminosilicate or layered silicate detergent builders
    Patent number: 5108646
    Abstract: A process for making detergent builder agglomerates by mixing crystalline aluminosilicate or layered silicate detergent builder with selected binder in an energy-intensive mixer to form free flowing agglomerates. The binder is an anionic synthetic surfactant paste or a water-soluble polymer containing at least about 50% by weight of ethylene oxide, and optionally may contain minor amounts of ethoxylated nonionic surfactant. The agglomerates are also substantially free of amorphous alkali metal silicates if free water is present.
