Lubricant
Castor Oil is a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. If we compare Castor Oil as lube to other vegetable oil lubricants it can be seen that Castor Oil lubricants have better low-temperature viscosity qualities and high-temperature lubrication.
In countries all over the world, vegetable oil is often used as a lubricant because it has good lubricity and biodegradability. In addition, it is also favoured over petroleum-derived lubricants. Due to the properties like oxidative stability and performance at low temperatures, vegetable oils are limited in their widespread use as lubricants.
