PURPOSE:To obtain a refrigerator oil composition, stable to a refrigerant, such as fluorocarbon based compounds, etc., and having excellent seizure resistance, etc., by blending a base oil with a specific amount of a specified fluorinated silicone compound. CONSTITUTION:The aimed composition obtained by blending (A) a base oil consisting of mineral oil and/or synthetic oil with (B) 0.0005-50wt.% (especially preferably 0.01-10wt.%) fluorinated silicone compound expressed by the formula (R<1> and R<2> are 1-20C alkyl, 6-30C aryl, 6-30C cycloalkyl, 1-20C fluorine- substituted alkyl, 6-30C fluorine-substituted aryl or 6-30C fluorine-substituted cycloalkyl; R<3> and R<4> are 1-20C fluorine-substituted alkyl, 6-30C fluorine- substituted aryl or 6-30C fluorine-substituted cycloalkyl; m is 1-100). |
