Abstract
Detergent compositions containing organic surface active agents, water-insoluble aluminosilicate ion exchange materials, sodium silicate having an SiO.sub.2 :alkali metal oxide weight ratio of from about 1.4:1 to 1.9:1, and a hydratable salt of a water-soluble weak organic acid. The composition is produced by drying an aqueous slurry. The resulting composition is an effective laundry detergent in the form of crisp, free-flowing granules which are highly soluble when made and which maintain their solubility on aging.
