Abstract
A grease composition using lubricating base oil that is biodegradable by microorganisms in nature and has an affinity to the human body is provided. More particularly, a distillation residue secondarily generated in production of biodiesel from vegetable oil (soybean oil and canola oil) is used as the lubricating base oil.The grease composition is produced by adding 1 to 20 wt % of additives to 100 to 95 wt % of distillation residues, which is generated in production of biodiesel, and 1 to 30 wt % of thickeners.
