Abstract

An improvement in the process for the production of powdery washing and cleansing agent compositions containing finely-divided water-insoluble silicate compounds, capable of binding calcium, soap, and, optionally, other surface-active compounds, builders and other customary detergent additives by spray-drying a slurry and recovering said powdery washing and cleansing agent composition which comprises separately spray-drying a slurry rich in said silicate compounds and combining the spray-dried powders with the remaining ingredients in powdery form; as well as the powdery washing and cleansing agents so produced.
