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 comprising a liquid nonionic surfactant and also, a soap and/or wherein the weight ratio of the liquid nonionic surfactant to the soap and/or fatty acid is at least 2:1, to produce the detergent granules;
- the second liquid binder having a different composition from said first liquid binder and the weight ratio of the first liquid binder to the second liquid binder being from 15:1to 1:1, preferably from 10:1to 1:1, more preferably from 5:1to 1:1, most preferably from 3:1to 2:1.
