Abstract
A process for the preparation of detergent granules, the process comprising: (i) a first step of admixing in a mechanical granulator, an aluminosilicate and a first liquid binder comprising at least one surfactant, to produce a powder; and (ii) a second step of admixing in a low shear granulator, the powder produced in step (i), a water soluble salt and a second liquid binder, to produce the said detergent granules; wherein in step (ii), no more than 2%, preferably 0% by weight of the aluminosilicate based on the weight of the detergent granules is introduced into the low shear granulator of step (ii).

- (i) a first step of admixing in a mechanical granulator, an aluminosilicate and a first liquid binder comprising at least one surfactant, to produce a powder;
- and
- (ii) a second step of admixing in a low shear gas fluidization granulator, the powder produced in step (i), a water soluble salt and a second liquid binder, to produce the said detergent granules;
- wherein in step (ii), no more than 2%, preferably 0% by weight of the aluminosilicate based on the weight of the detergent granules is introduced into the low shear granulator of step (ii);
- and wherein no more than 9% by weight of the water soluble salt, based on the weight of the detergent granules, is introduced into the mechanical granulator of step (i).
