摘要: Abstract The ternary diagram of a surfactant-free microemulsion (SFME) containing 1-octen-3-ol as oil phase and ethanol the “double solvent” was constructed. Three regions O/W, B.C. W/O were identified by conductivity measurement UV–vis spectroscopy. With an increase in content, magnitude change surface tension SFME is comparatively larger both O/W regions, but smaller region. This pattern reflects difference microstructures each region system. autocorrelation function dynamic light scattering (DLS) determined, double exponential decay phenomenon observed. SFMEs ascertained use DLS method. observed from negative staining TEM measurements. It found that contain spherical droplets, whereas system bicontinuous structure. solubilization riboflavin measured spectrophotometry. has good ability for riboflavin, similar to traditional systems. curcumin also determined. solubilized amount reached maximum 17.65 mg/ml, approximately 10,000 fold compared its water solution. higher stability thermal than those
