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.

Abstract: The invention relates to a laundry, dishwashing or cleaning product detergent portion having two or more detersive components of which at least two are to be released into the liquor at different points in time in a laundering, dishwashing or cleaning process, said portion comprising at least one release controlling (physico)chemical switch which is not subject or not exclusively subject to temperature control, and also one or more substances for increasing the extent of the shift in pH.
