A process for making a thixotropic detergent slurry, particularly suitable for compositions useful in household automatic dishwashers comprises forming a slurry of particles of alkaline water-soluble builder salt, particularly sodium tripolyphoshphate, in a liquid containing dissolved alkalie builder salt, such as alkali metal carbonate. The proportion of solid particles is such that the slurry has a viscosity of 20,000 to 60,000 centipoises. The slurry is subjected to wet grinding with a high speed disperser, water and powdered clay are then added and the clay is deagglomerated by mechanical action. Compositions containing potassium compounds and water-soluble polymers are also disclosed. <IMAGE> |
