Petrolatum
Petrolatum (Vaseline) is the malthenes purified from lubrication oil, the mixture of residue oil and cerate. It is an important lubricant for medicines, cosmetics, fine chemical raw materials and precision instruments. In China, major vaseline products include ordinary vaseline, industrial vaseline and medical vaseline. Ordinary vaseline is suitable for the preparation of various ointments and softener of dark rubber products; industrial vaseline can be used to protect metal products and general machinery parts against rust and lubricate machines under light loads, but also can be used as treating compound for leather and rubber softener. Vaseline products are mainly concentrated in the medicinal Vaseline, which is divided into two: medical white vaseline and medical yellow Vaseline. Medical Vaseline is mainly used in the preparation of ointment, skin protection cream and cosmetics raw materials, as well as antirust and lubricating materials for medical instruments and precision instruments.
USES
With the characteristics of no color or smell, chemical inertness, semisolid, lipophilic property and good adhesion, it is suitable to manufacture substrates of hair cream, hair conditioner, eye cream, lipstick, wax matrix and so on. Medical petrolatum (vaseline) can be widely used as the matrix of ointment because it is almost compatible with all drugs without changes in drugs. Hydrophilic vaseline can be prepared by adding alcohols such as stearyl alcohol, cetyl alcohol and cholesterol after heated fusion and sufficient stir. Hydrophilic vaseline is an ointment base with strong permeability, stability and small stimulation. This ointment matrix can be used alone for dry skin rash, erythema, papules and other diseases, especially for the removal of blood scab and desquamation. Vaseline can also be used as a non-ionic emulsifier to be compatible with cholesterol, so the range of compatibility is very wide. In addition, it can be compatible with liquid drugs or aqueous solutions of drugs because of its absorbability. Industrial vaseline can be used as rubber softener, anti-rust of metal devices and raw material of rust proof grease.
