Detergency of sodium dodecyl benzene sulfonate and coconut fatty acid diethanol amide mixture, the representative components of liquid hand dishwashing detergents, was tested by several formulations; using oily soil and applying three testing methods, dynamic foam test, emulsifying test and practical hand dishwashing test.<BR>Test results obtained by these three methods resembled with each other, however the result by emulsifying test had closer correlation to the result obtained by practical hand dishwashing test than that by dynamic foam test.<BR>As a result it was recognized that emulsifying effect closely related to dishwashing detergency, and that, as the proportion of fatty diethanol amide increased the detergency at 30°C increased, but at 20°C it increased at first and then decreased after reaching maximum.<BR>Some of the commercial dishwashing detergents were tested by emulsifying test and practical hand dishwashing test, which showed good coincidence.
