    Abstract: PROBLEM TO BE SOLVED: To provide a freezer oil for hydrocarbon refrigerants, which enables both of the reduction of a viscosity and the maintenance of a refrigerant-dissolved viscosity to be achieved, and enables both of the compatibility of the refrigerant with a freezer oil and the maintenance of the refrigerant-dissolved viscosity to be achieved, and to provide a hydraulic fluid composition for freezers. SOLUTION: The freezer oil of the present invention for hydrocarbon refrigerants contains an ester of a polyhydric alcohol with a fatty acid containing 14 to 20C branched fatty acids of 40 to 100 mol%. The hydraulic fluid composition of the present invention for the freezers contains an ester of the polyhydric alcohol with the fatty acid containing the 14 to 20C branched fatty acids of 40 to 100 mol%, and the hydrocarbon refrigerant.
