Abstract: We detailed the stability of ELM with glutamic acid dialkyl esters as surfactants by moving single drop method. It is a new method which can overcome the weakness as the surface area of W/O emulsion drops cannot be measared accurately because the diameters of the emulsion drops are widely dispersed in the stirring method. Moreover, it may avoid the membrane breakup causing by mechanical stirring. It is a available method to measure the stability of ELM.

Key words: Moving single drop, Emulsion liquid membrane, Stability, Glutamic acid dialkyl ester, Surfactant
