ABSTRACT
The phase behavior and microstructure of several mixed nonionic and anionic surfactants systems in the liquid crystal state are addressed in this chapter. The relationships and parameters for microstructural analysis of liquid crystals by Small Angle X-ray Scattering (SAXS) are summarized, and then used to explain certain changes in self-organization. Comparison of theory and experiments is presented for nonionic surfactant mixtures. The solubilization of oils in mixed systems is also discussed. Systems closely related to applications such as sucrose and polyglycerol fatty acid esters as well as novel surfactants, such as poly(dimethylsiloxane) surfactants, are also included.
