White oil is deeply refined to remove sulfur, nitrogen, oxygen and aromatic hydrocarbons Colorless, tasteless, odorless and non-corrosive special mineral oil containing impurities.
White oil can be classified according to the purity of saturated hydrocarbons. Commonly used product categories are: industrial grade white oil, cosmetic grade white oil, and medical grade white oil. and food grade white oil, etc. Among them, medical grade white oil is used as base oil for ointments and pharmaceuticals, release agent for pills, anti-corrosion lubrication for surgical instruments and pharmaceutical machinery, etc.
White oil is widely used in veterinary vaccines:
After the 1960s, the veterinary vaccine research department conducted comparative tests on the effects of various immune adjuvants and believed that oil emulsions adding mineral white oil could significantly improve the immunity of animal vaccines. The use of white oil in the vaccine industry is mainly for the production of inactivated vaccines. It is used as an adjuvant. After the vaccine antigen is processed, it can be added and emulsified.
White oil is a hydrocarbon. Except for extremely small impurities, its components are carbon and hydrogen. Its products are stable. The carbon chain of white oil used in general animal vaccine production is maintained at around 19. The longer the carbon chain, the poorer the absorption, and the shorter the carbon chain, the greater the toxicity. According to market feedback and other relevant experimental data, No. 7 white oil is specially used for general animal vaccines. The hydrocarbon content of the oil is about 19, and it can float up and down. However, the greater the float, the wider the cutting width of the white oil is, which means that the production accuracy is not that high.
With the development of biotechnology, domestic animal vaccine companies have slowly adjusted and optimized the white oil components and adjuvant formulas, and some companies have begun to experiment with using viscosity Low viscosity white oil of about 5, or blending 5 viscosity white oil and 7 viscosity white oil to produce white oil with a viscosity of about 6 for production use. There are various methods, all in order to improve the potency and meet the requirements of breeding enterprises.
