Abstract
The present invention relates to an energy saving process for preparing concentrated or condensed surfactant granules. High active surfactant paste is chilled and granulated using fine dispersion mixing. The product surprisingly provides discrete, uniform (200-2,000 micron) granular particles. The granules of the present invention are preferably pure surfactant to be used as an intermediate in a final detergent formulation.
