Test method for turbidity point of surfactant
SH412 Automatic surfactant turbidity point tester is designed and manufactured according to the requirements of the national standard GB/T5559-2010 "ethylene oxide type and ethylene oxide - propylene oxide block polymerization non-ionic surfactant turbidity point determination", suitable for the determination of light-colored chemical products turbidity point.
Detailed definition
The solubility of nonionic surfactant in aqueous solution decreases with the increase of temperature. When it rises to a certain temperature, turbidity appears. Two liquid phases can be obtained by placing or centrifugation, and this temperature is called the turbidity point of the surfactant
