  • Process for making peroxyacid containing particles
    Patent number: 5536435
    Abstract: A process for preparing particulate bodies containing a substantially water-insoluble organic peroxyacid compound, which process does not include a solidification step, including an early step of intimately mixing substantially water-insoluble peroxyacid compound with a peroxyacid-stable, water-soluble surfactant.
    Type: Grant
    Filed: November 23, 1993
    Date of Patent: July 16, 1996
    Assignee: The Procter & Gamble Company
    Inventors: Benjamin E. Chapman, Steven M. Gabriel, Jeffrey E. Boucher, Daniel L. Strauss
  • Process for preparing thixotropic liquid detergent compositions
    Patent number: 5510047
    Abstract: A process for preparing viscoelastic, thixotropic, liquid, polymer-containing detergent compositions which exhibit increased density, enhanced aesthetics and improved rheological efficiency of the polymer is provided. The polymer thixotropic thickening agent is simultaneously added and mixed as a slurry to a premix under moderate to high shear rate to neutralize and disperse the polymer. The product is deaerated to increase density and enhance aesthetics by continued mixing under low to moderate shear rate of the slurry/premix composition. Sequential addition and mixing to the slurry/premix of organic solvent, oil, suds suppressors and solid material can aid in the deaeration step.

  • Liquid automatic dishwashing compositions containing metal salts of hydroxy fatty acids providing silver protection
    Patent number: 4859358
    Abstract: Thickened aqueous automatic dishwashing detergent compositions containing optional bleach-stable surfactant, detergency builder, hypochlorite bleach (to yield available chlorine), a thickening agent and metal salts of long chain hydroxy fatty acids. The compositions have a yield value between 50 and 350 dynes/cm.sup.2 and inhibit tarnishing of sterling and silver-plated flatware.
