This standard specifies the separation of surfactants and detergents, particle size, total phosphorus pentoxide, total active matter, non-ionic surfactants, various forms of phosphate, tosylate, foaming power, Chelating agent (EDTA), apparent density, whiteness, moisture and volatile matter, 4A zeolite content, active oxygen, alkaline protease activity, available chlorine and other 16 test methods. This standard applies to the index determination of surfactants and detergent products. When using the method of this standard to determine the sample, the appropriate method should be selected in combination with the characteristics of the specific sample.
