Enzymes in detergents

Factors affecting the performance of proteolytic and amylolytic enzymes in an anionic and nonionic detergent formulation have been studied using stain removal from EMPA blood-milk-ink and cocoa-milk-sugar soil test cloths as a measure of enzyme activity in the detergent solution. Factors considered include enzyme concentration, and temperature and pH of the wash solution. Results on stability of these enzymes in the two detergent formulations under accelerated storage conditions are also given. Presented at the AOCS Meeting, New York, October, 1968.
