  • Stable aqueous antimicrobial lipase enzyme compositions
    Patent number: 8227397
    Abstract: The disclosure relates to an enzyme stabilization system, compositions with the enzyme stabilization system, and methods of using the enzyme composition. Preferred ratios of acid to amine are effective at stabilizing enzyme. Optional nonionic surfactants and solvents also positively contribute to enzyme stability. The compositions are useful in cleaning applications.
    Type: Grant
    Filed: May 11, 2011
    Date of Patent: July 24, 2012
    Assignee: Ecolab USA Inc.
    Inventors: Brandon L. Herdt, Werner Strothoff, Alice Siegmann
