Product Application of Mineral oil CAS#8042-47-5

Mineral oil serves as a covering layer for microdrops of culture medium in petri dishes. It is an active component in baby lotions cold creams ointments and cosmetics. It is also used in electrical and mechanical industries as heat transfer fluid in electrical parts and non-conductive coolant. It can be used as transformer oil rust inhibitor for blades and insulator in high voltage switchgear. In addition it is used to store reactive metals such as lithium sodium and so on and suspend crystals in X-ray crystallography.
