PURPOSE:To provide the subject new composition containing a polyglycol compound and a dibasic acid ester, etc., exhibiting excellent solubility in a fluoroalkane refrigerant at high temperature and having good lubricity. CONSTITUTION:The objective composition contains (A) a polyglycol compound expressed preferably by formula I and/or formula II (R<1>, R<3> and R<7> to R<9> are H, hydrocarbon group or acyl; R<2> and R<4> R<6> are 2-6C alkylene; p, r and s are >=2) and (B) one or more substances selected from dibasic acid ester, fluorinated oil, polyhydric alcohol ester and fluorinated silicone. The amount of the component B is usually 0.01-50wt.% (especially 0.1-30wt.%) based on the sum of A and B. |
