Vegetable oils are promising candidates as base fluid for eco-friendly lubricants because of their excellent lubricity, biodegradability and low evaporation loss.  Their use, however, is restricted due to low thermo-oxidative stability and poor cold flow behavior.  This paper presents a systematic approach to improve the oxidation and cold flow behavior of vegetable oil derivatives (chemical modification and additive technology).  Vegetable oil based lubricants formulated using the above approach exhibit superior oxidative stability, improved low temperature properties such as pour points and better wear properties compared to some of the commercially available industrial oils.  The above technology has been patented (U.S. Patent 6,583,302) and currently is being used in the hydraulic fluid industry along with other industrial applications.<br/>
