What is Standardized Detergency Evaluation Method about?
This paper describes a standardized laboratory method for evaluating the fabric soil removal efficiency of heavy-duty detergents. The method uses a Tergotometer mechanical tester, standardized cotton soil fabrics, and carefully controlled water hardness and operating times. Tests of two anionic detergents at different water hardnesses found standard deviations of 0.74% at 50 ppm hardness and 1.03% at 135 or 300 ppm, demonstrating the precision of the method.
