Zeolite-containing detergent compositions and process for preparing same.

摘要

Spray-dried detergent compo9itions prepared by spray-drying aqueous slurries comprising high concentrations of alkali metal silicates in combination with aluminosilicate particles which have been coated with from 100 ppm to 2000 ppm of a cationic surfactant contain fewer large aggregates which can deposit on washed fabrics as floc than is the case when the aluminosilicate is not so coated. The improvement is believed to result from an inhibition of the bridging of aluminosilicate particles by silicic acid.
