Abstract

Disclosed is a process for preparing non-aqueous, particulate-containing liquid laundry detergent compositions which are in the form of a suspension of particulate material, preferably including peroxygen bleaching agent and an organic detergent builder, dispersed in a liquid phase structured alkylbenzene sulfonate anionic surfactant-containing powder. The compositions so prepared provide especially desirable cleaning and bleaching of fabrics laundered therewith and also exhibit especially desirable pourability and chemical and phase stability.
