(57) [Summary] [Structure] W consisting of an emulsifier having a property of forming a liquid crystal phase in water, an organic substance such as wax, squalene, triglyceride, and fatty acid, an inorganic substance such as soil and dust, and water. The / O-based emulsion is used as a contaminated liquid for preparing an artificially contaminated cloth, and this is applied to the cloth to obtain an artificially contaminated cloth for evaluating the cleaning performance of the cleaning agent. [Effect] It exhibits a cleaning behavior similar to that of cleaning a natural soiled cloth, and in particular, it can accurately evaluate the cleaning power of a detergent containing a chelating agent. In addition, oil-soluble stains and water-soluble stains can be uniformly applied to the cloth at the same time. |
