  • Surface active polymers as detergents
    Patent number: 7741264
    Abstract: Provided herein are compositions useful as detergents in cleaning a wide variety of substrates, including hard surfaces and laundry. The compositions contain a water-soluble polymer, which is a co-polymer between a polymerizable amide and a second, ethylenically-unsaturated monomer. The polymerizable amide itself is prepared from an amine-capped, alkoxylated alcohol by reaction with maleic acid anhydride. Compositions according to the invention show enhanced cleaning performance and beneficial anti-redeposition properties.
    Type: Grant
    Filed: January 25, 2005
    Date of Patent: June 22, 2010
    Assignee: Huntsman Petrochemical LLC
    Inventors: George A. Smith, Duy T. Nguyen, Katie R. Hand, Samir S. Ashrawi
  • Enhanced solubilization using extended chain surfactants
    Patent number: 7467633
    Abstract: The present invention provides a surfactant blend that includes an extended chain surfactant and high HLB nonionic surfactant. The surfactant blend may be incorporated into household and industrial-institutional cleaning products to solubilize hard to remove oily stains and soil from a variety of surfaces.
