From the viewpoint of the adsorption of nonionic surfactant molecule to the interface, the active control of the supercooling degree was examined. And, it was clarified that the supercooling degree could be actively controlled by the change of the surfactant concentration. In this paper, in order to improve the controllability of the degree of supercooling, amphoteric surfactants were mixed with pure water fixed at pH 8 (amphoteric surfactant molecules are anionic), and the degree of supercooling was measured at various concentrations under voltage application. The characteristics of the degree of supercooling in the case of amphoteric surfactants were clarified by comparing the results of applied and non-applied voltages.
