Abstract

A detergent additive for commercial detergents (softener agents) that contain fabric softeners is described. This additive is based on agglomerates of a smectic laminar silicate coated with divided particles. This detergent additive is characterized in that the agglomerates are at least partially coated with particles of a cation exchanger that will pass through a screen with a mesh of about 45 .mu.m and have an average particle size of less than about 10 .mu.m, where the amount of cation exchanger particles is about 2 to 30 wt % (based on the dry weight of the uncoated agglomerates). This detergent additive may be used in the conventional detergent formulations.
