Abstract: From past different vegetable oils have been used in food but now a day decreasing resources of mineral oil, the increasing environmental awareness and the growing prices of crude oil have created the interest in new environmental lubricant and additive candidates. In order to minimize friction and wear in machine elements lubricating oil plays an important role. Vegetable oils are renewable lubricants having properties like non-toxicity, viscosity-temperature characteristics, biodegradability, excellent lubricity and low volatility. Hence vegetable oils can be deserving candidates as base fluid for eco-friendly lubricants. Also Indian has a great potential of producing vegetable oil based lubricants. Most of the researchers showed that vegetable oils can be used as lubricant either by chemical modification or by blending additive for a particular application. So the present paper study shows potential of cotton seed oil as an alternating lubricant.
