Abstract (en)

[origin: EP2835418A1] A lubricant base oil that is a hydrocarbon oil having a kinematic viscosity at 100°C of 2.0 to 9 mm 2 /s, a viscosity index of 130 or more, a freezing point of -30 to -5°C, and an SBV viscosity at -20°C of 1,000 to 60,000 mPa·s, in which the freezing point of the lubricant base oil is higher by 10°C or more than a freezing point of raffinate obtained by bringing the lubricant base oil into contact with urea and removing paraffin that can be included in the urea.
