Vitamin E is widely used in pharmaceutical, food and cosmetic preparations.This paper discusses methods of preparing vitamin E emulsions by using sulfobetaine (SB) zwitterionic surfactants which have high electrolyte tolerance. The amount of vitamin E dissolved in water was analyzed by turbidity and UV absorption measurements. The emulsion droplet size was determined by laser light scattering. Microemulsions with small particle size and high resistance to oxidation in air can be obtained by solubilizing vitamin E in SB solutions at high concentrations (above %) The performance of a series of SB surfactants is compared in 1.5% solutions. A SB surfactant with a 12 carbon chain seems to be the most effective in dissolving vitamin E. The saturation value of vitamin E is increased about one order of magnitude by adding NaCl to the SB surfactant solutions. Emulsions formed in surfactant solutions containing NaCl (0 4-0.6 M) are stable at low surfactant concentrations such as 0.2-0.4 % The emulsion droplet sizes are below or around 200nm.
