GB/T 5559-2010 for ethylene oxide type and ethylene oxide-propylene oxide block coalescence type non-ionic surfactant cloud point determination. The standard describes the determination principle, specifies the requirements of equipment and reagents. Detailed description of the preparation method of the test solution, as well as the specific operation steps of cloud point determination, such as heating rate control, Observation method, etc. Through the standardized process, the cloud point of such non-ionic surfactants can be accurately determined, providing a key basis for product quality control and application performance evaluation, helping related industries to achieve standardization in surfactant detection, improve product mass and application effect.
