Abstract:
A process for making a granular detergent composition comprising the steps of:a) adding to a first fluid bed dryer a first feed stream comprising a component selected from the group consisting of a first powder, a first liquid, and mixtures thereof, to form a second feed stream; b) adding the second feed stream to a mixer, to form a fourth feed stream; c) optionally, adding to the mixer a third feed stream comprising a component selected from the group consisting of a second powder, a second liquid, and mixtures thereof; d) adding to a second fluid bed dryer the fourth feed stream to form the granular detergent composition; e) optionally, adding a portion of the second feed stream to the second fluid bed dryer by-passing the mixer; and wherein the granular detergent composition comprises 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, wherein at least a portion of the particles contain a detersive surfactant or a detergent builder.
