Production of detergent granulates

A process for the production of a granular detergent product, the process comprising spraying droplets of a liquid binder to contact a particulate solid starting material in a low-shear granulator, wherein:

• the maximum d3,2 average droplet diameter of the liquid binder is 200 μm, and
• the d3,2 average droplet diameter of the liquid binder is not greater than 10 times the d3,2 average particle diameter of that fraction of the total solid starting material which has a d3,2 particle diameter of from 20 μm to 200 μm, provided that if more than 90% by weight of the solid starting material has a d3,2, average particle diameter less than 20 μm then the d3,2 average particle diameter of the total solid starting material shall be taken to be 20 μm and if more than 90% by weight of the solid starting material has a d3,2 average particle diameter greater than 200 μm then the d3,2 average particle diameter of the total solid starting material shall be taken to be 200 μm,
• the process resulting in the granular detergent having not more than 10% by weight of granules with a diameter above 1.4 mm, wherein
• a first portion of the liquid binder is admixed with solid starting material in a pre-mixer to form a partially granular solid material and then a second portion of the liquid binder is sprayed to contact the partially granular solid material in the low-shear granulator to effect complete granulation.
