Abstract

Stable granular detergent compositions with good flow and dispensing properties are prepared using percarbonate bleach and selected sulfate salts. Thus, particles comprising builders and surfactants are prepared separately from percarbonate bleach particles of defined particle size. Water-soluble sulfate particles having a defined size range and no more than 40 ppm iron and no more than 5 ppm copper are used in the compositions. The specified moisture content of the ingredients and overall compositions improves stability and flow/dispensing properties.
