Abstract
Lubricating oils are derived from petroleum and are widely used in the industrial sector, with the aim of reducing wear caused by friction on metal parts. Currently, mineral lubricants are commercially the most used throughout the world, they are a complex mixture of paraffinic, olefinic, naphthenic and aromatic hydrocarbons with 20 to 50 carbon atoms. These are products of the union of two main components: chemical additives and base oil. The base oil is extracted from the petroleum refining process and the chemical additive is used to modify, preserve and intensify the physical and chemical characteristics of the product. They have greater oxidation stability and are cheaper than other types of lubricants. However, mineral lubricants have low biodegradability and release toxic materials into the environment (Karmakar et al., 2017).
