1.Medicinal Vaseline
This is a fatty petroleum product that is clear or yellow-brown in color, with a mineral oil smell, but no smell of kerosene. The dropping point is about 37-54 degrees. It is refined from residual oil via sulfuric acid and clay. It can be also be made from solid paraffin and mineral lubricating oil. It is very water repellent and does not mix with water.
Vaseline can be used as a lubricant, insulating compound, or in cosmetics and medicinal ointment, as well as wet and perfuse capacitors. It is also used as an antirust agent and water repellent. Medicinal white vaseline is an odorless soft paste with certain capacity of wire drawing and good chemical stability, with a smooth, greasy feel. It is used as auxiliary material for medicinal ointments and skin-protection, for corrosion prevention on precision instruments and medical devices, and as an ingredient in cosmetics and other daily-use products. It can be used to stop nose-bleeds and a small amount can be used for any minor wound to stop the bleeding. It can also be applied to minor burns to reduce the pain. Our annual production capacity is 5,000 tons.
