Study on nanoemulsion using various lecithins and oils

Nanoemulsions have many specific characters compared with general emulsions in aspect of stability, rheological property, uniformity, high interfacial tension and so on. Therefore we study on nanoemulsions with changing various lecithins and oils using microfluidizer. As lecithins, we used saturated lecithin, unsaturated lecithin and hydrogenated phosphatidylcholine. Caprylic capric triglyceride, Squalane, Macadamia nut oil, Liquid paraffins, Dimethicone, and Cyclomethicone were used as oils. To identify nanoemulsions, we measured paticle size, zeta potential, turbidity and transmission electron microscope.
