A laboratory test has been developed for screening detergent compositions with respect to the removal of natural dry particulate soil (dirt). The fabrics are soiled uniformly with dirt obtained from a suitable area and then laundered under controlled conditions in a Tergotometer. The total soil removal is determined instrumentally. The test enables the researcher to check the effects of many variables, such as temperature, water hardness, builders, fabric, etc., with a minimum amount of preparation and time. The soil removal data is analyzed by a suitable statistical method, and the results are good indicators of practical performance.
