Abstract
The present invention relates to an energy saving process for preparing condensed detergent granules. Dry detergent builders and a high active surfactant paste are finely dispersed into a uniform dough. The dough is chilled and granulated using fine dispersion mixing to surprisingly provide discrete, uniform (300-1200 micron) free flowing, granular particles. The granules of the present invention are preferably formulated to be fully formulated.
