Abstract: The invention provides disintegrant granules and a tablet of compacted particulate detergent composition comprising non-soap surfactant and detergency builder, wherein the tablet or a discrete region thereof comprises disintegrant granules comprising a water-swelling clay, a water-insoluble inorganic material and a water-swellable agent. The inorganic material is preferably silica or a crystalline aluminosilicate. The tablets show good disintegration properties, even upon storage. Especially good disintegration is obtained for tablets comprising disintegrant granules which comprise the water-swellable agent, which in its anhydrous state, comprises no more than 20% by weight of the combined weight of the swelling clay, the inorganic material and the water-swellable agent. A method of making the tablets is also provided.
