Abstract
A multi-step process for making a granular detergent composition. The processing steps include adding to a first fluid bed dryer a first feed stream selected from a first powder, a first liquid, and mixtures thereof, to form a second feed stream. The second feed stream is added to a mixer to form a fourth feed stream, and optionally, a third feed stream selected from a second powder, a second liquid, and mixtures thereof can be added to the mixer. The fourth feed stream is added to a second fluid bed dryer to form the granular detergent composition. The granular detergent composition contains at least about 50% by weight of particles having a geometric mean particle diameter of from about 500 microns to about 1500 microns with a geometric standard deviation of from about 1 to about 2. Further, at least a portion of the particles contain a detersive surfactant or a detergent builder.
