Abstract

A process for producing a particulate amorphous alkali metal silicate having a molar ratio of M.sub.2 O to SiO.sub.2 of 1:1.5 to 1:3.3 by PA1 a) spray-drying an aqueous mixture of amorphous alkali metal silicate, PA1 b) impregnating the spray-dried amorphous alkali metal silicate with an aqueous dispersion or solution of detergent composition components containing at least one organic component, and PA1 c) optionally drying the impregnated amorphous alkali metal silicate.
