  • Enzymatic detergent composition and method for degrading and removing bacterial cellulose
    Patent number: 6020293
    Abstract: This invention relates to an enzymatic detergent drain cleaner composition containing:0.015-20 wt % of an acid cellulase enzyme having hydrolytic activity specific to .beta.-glucosidic bonds;1-70 wt % of a water soluble carbonate salt;1-70 wt % of a water soluble acid that reacts in an aqueous medium with the carbonate salt to form carbon dioxide that dissolves in the aqueous medium;0.1-10 wt % of a surfactant; and0.05-5 wt % of a thickening agent. This detergent composition may be used as an enzymatic detergent drain cleaner or in a method for removing or preventing bacterial cellulose deposits in an aqueous system at a solution temperature of up to about 60.degree. C. and a pH of about 2 to about 7.
    Type: Grant
    Filed: June 11, 1998
    Date of Patent: February 1, 2000
    Assignee: Kay Chemical Company
    Inventors: Fahim U. Ahmed, James E. Goldschmidt, Gerald E. La Cosse
  • Enzymatic detergent composition and method for degrading and removing bacterial cellulose and glycerides
    Patent number: 5975095
    Abstract: This invention relates to an enzymatic detergent drain cleaner composition comprising:about 0.005% to about 20% by weight of an acid lipase having hydrolytic activity to ester bonds, specific to glyceride linkages;about 0.005% to about 20% by weight of an acid cellulase enzyme having hydrolytic activity specific to .beta.-glucosidic bonds;about 1-70 wt % of a water soluble carbonate salt;about 1-70 wt % of a water soluble acid that reacts in an aqueous medium with the carbonate salt to form carbon dioxide that dissolves in the aqueous medium;about 0.1-10 wt % of a surfactant; andabout 0.05-5 wt % of a thickening agent. This detergent composition may be used as an enzymatic detergent drain cleaner or in a method for removing or preventing bacterial cellulose and glyceride deposits in an aqueous system.
