GB/T 7383-2020

This standard specifies the method for determining the hydroxyl value in non-ionic surface active agents, which is a key parameter for assessing the concentration of hydroxyl groups in polyols and ethoxylates. It is applied in the chemical industry for quality control and formulation development of surfactants used in detergents, emulsifiers, and industrial cleaning products. The testing context involves laboratories performing titration-based analysis to ensure product consistency and compliance with manufacturing specifications.
