ABSTRACT:
A process for the preparation of detergent granules, the process comprising:(i) a first step of admixing in a mechanical granulator, a solid component and a first liquid binder, to produce a powder; and(ii) a second step of admixing in a low shear granulator, the powder produced in step (i), and a second liquid binder, to produce the detergent granules;the second liquid binder having a different composition from the first liquid binder and the weight ratio of the first liquid binder to the second liquid binder being from 15:1 to 1:1, preferably from 10:1 to 1:1, more preferably from 5:1 to 1:1, most preferably from 3:1 to 2:1.
