Background

In the machine maintenance industry, when working, a worker often contacts a machine to be repaired with hands, and the general maintenance parts have engine oil, lubricating oil and the like, so that the hands of the worker are contaminated. In daily life, people can often see that the machine maintenance personnel are stained with the engine oil after completing the operation, the oil stain is difficult to clean by using a common cleaning agent, some cleaning agents are greasy when being washed, and meanwhile, the problems of long cleaning time, low cleaning efficiency and poor cleaning effect exist, and the requirements of the operation personnel cannot be met.

Engine oils, i.e. engine lubricating oils, having a density of about 0.91X 10³(kg/m³) The engine oil consists of base oil and an additive, the additive can make up and improve the deficiency of the base oil in performance, and endows certain new performances, which are important components of the engine oil; the base oil is a main component of the lubricating oil, and determines basic properties of the lubricating oil, and the base oil can be classified into mineral oil, synthetic oil, vegetable oil, and animal oil. The animal oil is often used on gears of various large machines, has good wear resistance and pressure resistance, and is base oil which is frequently contacted by operators.

Based on the animal base oil, the invention develops the oil removing agent, which can effectively remove the machine oil which is stained on hands and clothes of machine maintenance workers and takes the animal oil as the base oil, and effectively improve the trouble that the oil stain of the machine maintenance workers is difficult to remove.
