Zusammenfassung:PURPOSE:To obtain the subject composition, having remarkable antioxidizing effects and useful as a refrigerating compressor for air conditioners and refrigerators, etc., by using zinc thiophosphate and a phenolic derivative in combination as an antioxidant, adding and mixing both with an ester-based synthetic oil. CONSTITUTION:The objective composition is obtained by adding and mixing zinc thiophosphate expressed by formula I and a phenolic derivative expressed by formula II in respective amounts of 0.5-1.5wt.%, preferably 0.7-1.0wt.% based on a base oil in combination as an antioxidant with an ester-based synthetic oil. Furthermore, an epoxy-based hydrochloric acid capturing agent, a defoamer, etc., other than the antioxidant can be added to this composition to reduce the temperature of a refrigerating machine and suppress the foaming.
