Abstract
A self-sustained electrical oscillation observed in a water/oil/water system in which one of the water phases contains sodium oleate as a surfactant is interpreted in terms of the diffusion of oleate anions in water and their absorption into the oil phase by formation of inverted-micelles. The model also accounts for the observed result that the self-sustained oscillation is stable only for a specific range of sodium oleate concentration.
