PURPOSE:The rolling oil that is obtained by allowing the oil component containing a specific emulsifier and water to emulsify into a W/O type or W/O/W type emulsion, thus satisfying both emulsion stability and water-staining resistance. CONSTITUTION:The objective rolling oil is obtained by emulsifying (A) 5-40 wt% of the oil phase component containing 2-15wt% of an emulsifier of 3- 5 HLB, optimally a mixture of 40-80wt% of oleic acid of about 1 HLB and 20-60wt% of polyoxyethylene sorbitan(n)oleate (n=1, 3, 5) and the rest amount of water, into W/O type or W/O/W type emulsion.
