A review of biodegradable lubricants 3. Caracterization, current status, and future improvement trends

Abstract

The history of biodegradable lubricants has been presented in a series of articles, works and patents. Biodegradable lubricants are used to improve the properties of mineral oils or vegetable oils. To improve the properties of the oils, a wide range of biodegradable lubricants based on polymers were synthesized. A series of researches are related to the production of biodegradable lubricating oils that also possess a food-type non-toxic character.
