Process for making a detergent particle

摘要

There is provided a process for applying a coating to a base particle comprising a hygroscopic material, particularly sodium silicate, comprising the steps of (i) spraying an aqueous mixture comprising organic binder and optionally a dyestuff onto the base particle; and (ii) drying the particle to obtain a finished particle wherein the weight ratio of hygroscopic material to organic binder in the finished particle is from 1000:1 to 10:1, expressed on a dry weight basis. Detergent compositions containing the resulting particles are also provided
