  • Liquid peracid precursor colloidal dispersions: macroemulsions
    Patent number: 5977044
    Abstract: A stable liquid peracid precursor composition for delivering a bleaching and cleaning material is provided in which the liquid peracid precursor composition combines a dispersion medium which comprises a stabilizing effective amount of a liquid matrix and an emulsifier, and a dispersed phase that comprises a peracid precursor. The bleaching and cleaning material comprises either a hydrophobic or hydrotropic generated mono- or diperoxyacid, or mixtures thereof.
    Type: Grant
    Filed: December 22, 1997
    Date of Patent: November 2, 1999

  • Process for making acid activated bleaching earth using high susceptibility source clay and novel bleaching earth product
    Patent number: 5008227
    Abstract: A process for making acid-activated bleaching earth from a crude attapulgite clay. A crude is selected which is mildly acidic and contains at least about 90% attapulgite. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower production costs (no washing, filtering, or waste treatment steps) and environmental soundness (no harmful environmental waste products are produced).
    Type: Grant
    Filed: May 16, 1989
    Date of Patent: April 16, 1991
    Assignee: Engelhard Corporation
    Inventors: Dennis R. Taylor, Charles B. Ungermann
  • Process for making acid activated bleaching earth using high susceptibility source clay and novel bleaching earth product
    Patent number: 5008226
    Abstract: A process for making acid-activated bleaching earth from certain naturally occurring mixtures of calcium bentonite and attapulgite clay. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower production costs (no washing, filtering, or waste treatment steps) and environmental soundness (no harmful environmental waste products are produced).
