摘要： A multi-phase liquid composition comprising a conductive liquid and a non-conductive liquid, said liquids being non miscible, wherein the conductive liquid comprises more than 90% up to 99.9% by weight of a first component having a surface tension above 45 mN/m and comprising water, salt and at least one freezing point lowering agent, and from 0.01% to less than 10% by weight of a second component having a surface tension below 30 mN/m and comprising at least one first compound, wherein said at least one first compound is a non ionic surfactant.
