  • Patent number: 6087320
    Abstract: A stable, pumpable, flowable and pourable surfactant concentrate, and a method of preparation thereof, said concentrate consisting essentially of (a) at least one anionic or amphoteric surfactant, (b) at least one alkylpolyglycoside surfactant, (c) a viscosity-adjusting agent selected from the group consisting of inorganic and organic electrolytes and (d) water. The concentrate is economically shippable and easily handleable by the formulator for dilution with water, without gelation difficulties, for a variety of end-use applications with adjuvants usually associated with the desired end-use.
    Type: Grant
    Filed: April 25, 1996
    Date of Patent: July 11, 2000
    Assignee: Henkel Corp.
    Inventors: Allen D. Urfer, Virginia Lazarowitz, Patricia E. Bator, Barry A. Salka, Robert A. Aleksejczyk
  • Patent number: 5985167
    Abstract: Wet leather treating compositions and methods of wet treating leather hides employing alkylpolyglycosides for enhancing the penetration and absorption of the leather treatment formulations in an environmentally safe manner. The compositions are substantially free of volatile organic compounds.
    Type: Grant
    Filed: June 23, 1995
    Date of Patent: November 16, 1999
    Assignee: Hodgson Process Chemicals Inc.
    Inventors: Michael W. Counts, John A. Thompson, Jack O. Lavoie, Robert A. Aleksejczyk
  • Patent number: 5962399
    Abstract: A process for preparing high detergency or surfactant alkyl polyglycoside compositions and a purified alkyl monoglycoside and to compositions employing the polyglycosides for various end use applications. The process involves removal of a substantial portion of the monoglycoside present in a reaction product mixture containing alkyl polyglycosides resulting from the reaction of an alcohol and saccharide at elevated temperatures in the presence of an acid catalyst. Separation of the monoglycoside from the reaction product mixture may be carried out by molecular distillation.
    Type: Grant

  • Patent number: 5734029
    Abstract: An improved alkylpolyglycoside surfactant composition, and method of preparing same, by selecting an average chain length of the alkyl moiety of the composition and mixing two or more of at least binary components having an average alkyl chain lengths such that when mixed, the amounts thereof are effective to provide the predetermined, selected average alkyl moiety of the surfactant composition. The improved alkylpolyglycoside composition is used in a variety of end-use applications, including hard surface cleaners, laundry detergents, and personal care products, such as shampoos, soaps, facial cleansers, foam baths, toothpaste, mouthwashes, antiperspirants and the like.
