Alkyl polyglucosides are a class of amphipathic substances that contain a long hydrocarbon chain (branched or straight chain) and one or more glycosidic units and are nonionic surfactants. Studies on the physicochemical properties of such materials using phase diagrams, surface tension, interfacial tension, small-angle neutron scattering, and DSC have shown that APG is significantly different in many properties from conventional nonionic surfactants, especially APG has Higher cmc. The interaction between APG and other surfactants is different from that of conventional nonionic surfactants. The interfacial properties of APG in the temperature range of 25 ℃ ~ 60 ℃ are not temperature-dependent. The phase behavior of APG due to structural But there are significant differences; the formation and properties of APG microemulsion are obviously different from the traditional non-ionic surfactants; the cloud point properties of APG are different from the traditional non-ionic surfactants.
