  • Method of cleaning using liquid compositions comprising stabilized mixtures of enzymes
    Patent number: 4566985
    Abstract: A liquid enzyme cleaning composition. The composition includes a water base containing in solution a mixture of enzymes including a protease and at least one other enzyme. To inhibit the digestive effect of protease on the other enzymes in solution, the composition contains an effective amount of a benzamidine hydrohalide. At the time of use, the composition is diluted with additional water which releases the inhibitory effect of the benzamidine hydrohalide, so that the protease is free to act against proteinaceous soils in the material to be cleaned.
