White mineral oil usually refers to white mineral oil. It is a mineral oil that has undergone special deep refining. White oil is colorless and odorless, chemically inert and has good light stability. Its basic composition is saturated hydrocarbon structure, and substances such as aromatic hydrocarbon, nitrogen, oxygen and sulfur are close to zero. Because of this ultra-refining depth, it is difficult to carry out heavy fractions in the actual manufacturing process, so the molecular weight of white oil is usually in the range of 250-450. It has good oxidation stability, chemical stability and light stability, is colorless and tasteless, and does not corrode fiber textiles.

Because of this ultra-refining depth, it is difficult to realize heavy fraction in the actual manufacturing process, so the molecular weight of white oil is usually in the range of 250-450, which belongs to lubricating oil fraction. Medical white mineral oil is a colorless, odorless and transparent liquid with special plasticity, lubricity and heat preservation, which can be made into articles for human and animals to absorb or swallow, so it can be used for the manufacture of medicines and cosmetics, the manufacture and packaging of food, and the lubrication of food production and packaging machinery. White mineral oil for industrial use has low purity and can be used in special industries such as textiles, chemicals and plastics. So there is no harm.
