Abstract: PROBLEM TO BE SOLVED: To obtain excellent compatibility with lubricants and cooling agents by comprising a fluorine-containing hydrocarbon having a specific number of carbon atoms, an ester of a carboxylic acid with a polyhydric hydroxy com pound and an alkoxylated alcohol or phenol or an alkoxylated glycol at a specific ratio. SOLUTION: A composition comprises 10-90 wt.% fluorinecontaining 1-2C hydrocarbon; 5-90 wt.% ester of a carboxylic acid represented by the formula: R[OC(O)R ]n (wherein R is hydrocarbyl; R is H, 1-7C hydrocarbyl or the like; and n is 2-10) with a polyhydric hydroxy compound; and 0.1-5 wt.% alkoxylated alcohol or phenol represented by formula I (wherein R is 1-20C aliphatic, 6-24C aromatic or the like; R is H, methyl or ethyl; y is 1-3; and x is 2-50) or alkoxylated glycol represented by formula II (wherein R is 2-8C hydroxyalkyl; and R, y and x are the same as defined above).
