摘要：
Dry blended carbonate or phosphate-based laundry detergents are prepared by adding to unhydrated or partially hydrated builder salts, a pH buffering compound and a detergent active compound, together with other formulating agents, coarse, hydrous granular water soluble silicate particles, the silicate particles passing a 10 mesh screen and about 95% of the particles are retained on a 100 mesh screen, according to the disclosed method. Dry blended laundry detergents so formulated are substantially completely free of insoluble product lumps when used in cold wash water in the temperature range of 35.degree.-75.degree. F.
