Abstract
A process for improving the physical properties of granular detergents comprises making fine particles of calcium sulfite adhere uniformly onto the surface of the granular detergent. The amount of said calcium sulfite particles to be thus applied is in the range of from about 0.5 to about 5 wt.% relative to the granular detergent, and about 70 wt.% or less of this amount may be replaced with fine particles of alumino silicate. The applicable average particle diameter of calcium sulfite to be made to adhere onto granular detergent is less than about 4 .mu. and that of aluminosilicate is less than about 5 .mu..
