Published: April 2009

An immiscible interface, which was composed of CaCl(2) aqueous and ester phases, was excited by the addition of a small amount of water. The excitation, i.e., burst and flow at the interface, was observed above a critical concentration of CaCl(2) in the aqueous phase. The critical concentration and degree of excitation depended on the kind of ester. The mechanism of excitation is discussed in relation to the interfacial tension and the Marangoni effect.
