The first thing that comes to mind when talking about lubricants is, without a doubt, oil. People have been using plant and animal fat-based substances for greasing purposes for centuries. Petroleum byproducts came into the picture in the middle of the 19th-hundreds, and they are widely used today. However, fossil oil comes from finite sources. We have to look for an alternative. Secondly, oil is flammable. Thirdly, oil is expensive and pretty challenging to dispose of. The environmental impact of oil-based lubricants is indubitable.
There is a dire need for safer, cleaner, eco-friendlier, and more effective lubricant that does not deteriorate under extreme conditions.
