Abstract It was found from experiment that irregular oscillations of pH,electric potential and conductivity were produced at the interface between oil and water in the W_1/O/W_2 three phases system consisted with saturation Ca(OH)_2 aqueous,kerosene solution of oleic acid and CTAB aqueous.The mechanism was explained by substitution of components and comparison of additives.The oscillations were produced from becoming soap reaction between oleic acid and calcium alkali.Its product of surfactant-calcium soap was key component and CTAB was main assistants.The reversible property of the oscillation was also discovered with electrifying alternating current on the system after the reaction.And it can be explained by the changes of emulsion formation and break.
