The influence of the incorporation of cholesterol and water on the particle size, bilayer thickness, melting behavior, and relative sucrose ester composition of reversed vesicles was studied. Reversed vesicles (RVs) were prepared of sucrose ester in silicon oil by sonication. The RVs were characterized by polarized light microscopy, laser diffraction, high-performance liquid chromatography, small angle X-ray scattering (SAXS), and differential scanning calorimetry.

The vesicles were characterized by polarized light microscopy, freeze-fracture electron microscopy, and differential scanning calorimetry. Furthermore the ability to encapsulate p-aminobenzoic acid and cholesterol in such vesicles was studied.
