POUCHED GRANULAR DETERGENT COMPOSITIONS CONTAINING HYGROSCOPIC BUILDERS ABSTRACT OF THE DISCLOSURE A porous, pouched granular detergent compositions con- taining an organic surfactant, preferably an aluminosilicate ion exchange material, and water-soluble neutral or alkaline hygro- scopic detergency builder salt, preferably an ether polycarboxy- late. The pouched compositions contain no or low levels of phos- phate and silicate materials, yet provide granules which exhibit at least initial free-flowing granular characteristics, reduced dusting and unexpectedly good/equivalent solubility in the laundering solution notwithstanding the development of lumps upon storage under stress conditions.
