wherein said Component A is one or more selected from alkyleneoxide addition compounds simultaneously satisfying Conditions 1, 2 and 3 wherein Condition 1 is the condition of having a number average molecular weight of 1000-12000 and having alkylene oxide with 2-4 carbon atoms added to monohydric-trihydric aliphatic alcohol with 1-24 carbon atoms, Condition 2 is the condition of having polyoxyalkylene groups comprising oxyalkylene units of which 10-80% by weight are oxyethylene units, and Condition 3 is the condition of containing 35% by weight or more of alkyleneoxide addition compounds having ethylene oxide and propylene oxide added to monohydric aliphatic alcohol with 6-10 carbon atoms;
wherein Component B is one or more selected from alkylene oxide addition compounds with number average molecular weight of 140-800 having ethylene oxide or both ethylene oxide and propylene oxide to monohydric aliphatic alcohol with 6-10 carbon atoms, having polyoxyalkylene group of which more than 30% by weight of all constituent oxyalkylene units are oxyethylene units;
wherein Component C is one or more selected from ionic surfactants; and
