Provided is a lubricant composition which is excellent in thermal stability and chemical stability while making it possible to detect a leakage point of the lubricant composition, etc. with a fluorescent agent. The lubricant composition is one containing a base oil (A) and a fused ring compound (B) being fluorescent, having a tri- or higher fused ring, and not having nitrogen, oxygen, and sulfur in a molecule thereof, wherein the fused ring compound (B) is contained in an amount of 0.001 to 1.0% by mass on a basis of the whole amount of the lubricant composition.

Electrosurgical lubricants, sterilized kits including the lubricants, methods for using the lubricants, and methods for preparing sterilized kits having the lubricants therein. Electrosurgical devices utilize a high frequency electrical current to cut and to coagulate tissue during surgery. A problem of the electrosurgical devices is that the heat thereof causes tissue, such as that of a human being, to remain on the device and is generally difficult to remove, even with repeated washings. The electrosurgical lubricants have been found to considerably reduce the amount of eschar that builds up on electrosurgical devices, decrease the tendency of electrodes to stick to tissues at the surgical site, and prevent damage to the surface of the electrosurgical device.

Compounds and compositions, including engine oils and lubricant formulations comprising at least one estolide compound. Exemplary compositions comprise an estolide base oil and an additive package.

A method for preparing an estolide compound and an estolide compound prepared thereby are disclosed. The method for preparing an estolide compound includes: converting biomass fat into a fatty acid; separating the fatty acid into a C.sub.16 saturated fatty acid and a C.sub.18 unsaturated fatty acid; preparing a linear internal olefin (LIO); increasing an amount of oleic acid through partial hydrogenation of the C.sub.18 unsaturated fatty acid; synthesizing an estolide polymer through cross metathesis of the oleic acid; capping the C.sub.16 saturated fatty acid onto the estolide polymer; and reacting the estolide polymer with the linear internal olefin.
