ActiveSurface active agents—Determination of interfacial tension—Drawing up liquid films
表面活性剂 界面张力的测定 拉起液膜法
Application Summary AI generated
This standard specifies a method for determining the interfacial tension between two immiscible liquids by drawing up a liquid film, applicable to surface active agents and their solutions. It is used in chemical manufacturing and quality control laboratories to evaluate the performance of surfactants in formulations such as detergents, emulsifiers, and industrial cleaners. The method is particularly relevant for products where precise interfacial tension data is required for optimizing stability and efficacy in multiphase systems.
