Abstract
A granular detergent product is made by spraying a liquid binder to contact a particulate solid starting material in a low shear granulator such as a fluidized bed apparatus. The d average droplet diameter of the liquid binder is not greater than ten times the d average particle diameter of that fraction of the solid starting material which has a d particle diameter of from 20 &mgr;m to 200 &mgr;m provided that if more than 90% by weight of the solid starting material has a d average particle diameter less than 20 &mgr;m then the d average particle diameter of the total solid starting materials shall be taken to be 20 &mgr;m. If more than 90% by weight of the solid starting material has a d average particle diameter greater than 200 &mgr;m than the d average particle diameter of the total starting solid material shall be taken to be 200 &mgr;m.
