Abstract (en)

The present invention provides a biodegradable lubricating oil composition containing 50% by mass or more of a synthetic ester base oil (A), 0.1 to 3% by mass of an amine-based antioxidant (B1), 0.1 to 3% by mass of a phenol-based antioxidant (B2), and 0.01 to 2% by mass of a sulfur-phosphorus-based extreme-pressure agent (C), wherein the transmittance at 3,005 ± 1 cm -1 of a 0.1 mm-thick liquid film of the composition, as measured through IR absorptiometry, is 50% or more.
