Description

Among many test methods of detergency of dishwashing detergent, the most practical method has been plate dish wash test (practical hand dish washing test). In this report, a new test method (method A) which consists of a simple operation and has sufficient accuracy was proposed. Some of the commercial dishwashing detergents were tested by method A and by plate dish wash test, and the results showed good coincidence. Moreover, sodium N-acyl-L-glutamates were evaluated by method A as surfactants for dish washing detergent. Detergencies of the mixtures of sodium N-oleoyl-L-glutamate and dimethyllaurylamine oxide or coconut fatty acid diethanolamide were better than those of the components. Detergencies of sodium N-oleoyl-L-glutamate containing organic salts were also measured.
