Abstract
A process for preparing coated detergent granules in a fluidized bed. The fluidized bed is operated at a flux number of at least about 4 and at a Stokes Number of 10 to about 1000 using a coating solution or slurry having a viscosity from about 300 to about 100,000 centipoise, measured at 60° C. Upon drying, the resultant detergent particles have improved appearance and flow properties and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.
