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
m.sub.c/(m.sub.c+m.sub.p)=cl/r, where m.sub.c is the weight of the acidic
component, m.sub.p 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.
