Abstract
Coatings are applied to particulate detergent components or compositions to improve free-flow properties, improve dispensing and avoid dust formation. This is achieved by a two-step coating process, wherein the first coating step comprises mixing the detergent composition or component with a finely divided particulate material which is preferably aluminosilicate, and the second coating step comprises applying a coating agent. Suitable coating agents for the second step comprise from 5% to 95% by weight of cellulosic polymer; from 5% to 95%, by weight of sugar; and optionally, from 0% to 30% by weight of plasticizer.
