Abstract

A process for the production of particulate detergents or premixes suitable for their production by application of a flowable acidic component to a particle consisting at least partly of an alkaline detergent ingredient selected from the group consisting of alkali metal silicates, alkali metal alumosilicates, alkali metal perborates, alkali metal percarbonates, and mixtures thereof, the percentage of acidic component applied being governed by the formula mc/(mc+mp)=c·l/r, where mc is the weight of the acidic component, mp is the weight of the particle, r is the radius of the particle and c is a factor of 5 length units to 10 length units.
