White oil usually refers to white mineral oil. It is a special deeply refined mineral oil. White oil is colorless, odorless, chemically inert, and has good light stability. Its basic composition is a saturated hydrocarbon structure, and the aromatic hydrocarbons, nitrogen, oxygen, sulfur and other substances are close to zero. Due to this super refining depth, it is difficult to implement 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, light stability, colorless, odorless, and does not corrode fiber textiles. Due to this super refining depth, it is difficult to implement heavy fractions in the actual manufacturing process, so the molecular weight of white oil is usually in the range of 250-450, which is a lubricating oil fraction. Classification and use White oil is usually classified according to the purity of its saturated hydrocarbons. Commonly used are industrial grade white oil, cosmetic grade white oil, medical grade white oil, food grade white oil, etc.
Different classes of white oils also have different uses.
Industrial-grade white oil is obtained from base oil produced by hydrocracking, after deep dewaxing, chemical refining and other processes. It can be used in chemistry, textile, chemical fiber, petrochemical, electric power, agriculture, etc. PS, PU and other production.
Food-grade white oil is obtained by using mineral oil as the base oil, after deep chemical refining, edible alcohol extraction and other processes. It is suitable for the lubrication of processing equipment in the food industry such as grain and oil processing, fruit and vegetable processing, dairy product processing, bread cutting machines, etc. , biscuits, chocolate and other food release agent, can prolong the storage and preservation period of wine, vinegar, fruits, vegetables and canned food.
Medical grade white oil, suitable for the pharmaceutical industry, can be used as a defoamer for the production of laxatives for oral administration.
Cosmetic-grade white oil is obtained after deep refining using hydrogenated raw materials. It is suitable for the cosmetic industry and can be used as the base oil for ointments and softeners such as hair cream, hair oil, lipstick, face oil, skin care oil, sunscreen oil, baby oil, vanishing cream, etc.
