The surface activity, intermolecular interactions and thermodynamic parameters of a mixture of a nonionic surfactant (branched-chain alkyl glycoside (IG-10)) and an anionic surfactant (alcohol ether carboxylic acid (90H)) were investigated and the wetting, emulsifying and foaming properties of the mixed system were also evaluated. The results show that there is a mutual attraction at the mixed micelles and gas/liquid interfaces formed by the two surfactants. The thermodynamic parameters show that the formation of mixed micelles from two different surfactants is a non-ideal process. In terms of application performance, the wetting ability and foaming properties of the mixed system showed good synergistic effects, with the wetting time of the mixed system being shorter than that of the two single surfactant systems and the foam stability being weaker than that of the single system. The best emulsifying capacity was obtained when the mass fraction of 90H was 50 %.

支链烷基糖苷非离子表面活性剂与阴离子表面活性剂混合体系的性能研究

研究了非离子表面活性剂（支链烷基糖苷（IG-10））和阴离子表面活性剂（醇醚羧酸（90H））混合物的表面活性、分子间相互作用和热力学参数，以及润湿、乳化和发泡性能。还评估了混合系统的性能。结果表明，两种表面活性剂形成的混合胶束和气/液界面处存在相互吸引力。热力学参数表明两种不同表面活性剂形成混合胶束是一个非理想的过程。从应用性能来看，混合体系的润湿能力和发泡性能表现出良好的协同效应，混合体系的润湿时间比两种单一表面活性剂体系短，泡沫稳定性比单一表面活性剂体系弱。系统。当90H的质量分数为50%时，乳化能力最佳。
