  • Process for making high density detergent agglomerates using an anhydrous powder additive
    Patent number: 5486303
    Abstract: A process for preparing high density detergent agglomerates having a density of at least 650 g/l is provided. The process comprises the steps of: (a) charging a viscous surfactant paste into a mixer/densifier wherein the surfactant paste has a viscosity of from about 5,000 cps to about 100,000 cps and contains at least about 5% water; (b) adding from about 1% to about 70% of an anhydrous material into the surfactant paste just prior to entrance into the mixer/densifier to absorb at least a minor amount of the water from the surfactant paste; and (c) agglomerating the surfactant paste and the anhydrous material in the mixer/densifier so as to form detergent agglomerates having a density of at least about 650 g/l. The detergent agglomerates have high surfactant levels.
    Type: Grant
    Filed: August 3, 1994
    Date of Patent: January 23, 1996
    Assignee: The Procter & Gamble Company
    Inventors: Scott W. Capeci, James W. Osborn, Adrian J. W. Angell, Paul van Dijk
