White oil usually refers to white mineral oil that has been specially and deeply refined. Its basic composition is saturated hydrocarbon structure, with aromatic hydrocarbons, nitrogen, oxygen, sulfur and other substances almost zero. Due to this super refining depth, it is difficult to implement heavy fractions in actual manufacturing processes, so the molecules of white oil are usually within the range of 250-450. Has good oxidation stability, chemical stability, photostability, colorless, odorless, and non corrosive properties to fiber textiles.
White oil is mainly used as a raw material in industrial production processes, such as in oil-based shrinking products in the cosmetics industry; Alternatively, it can be used as a production aid, such as in the food processing industry for food polishing and film stripping; In addition, lubricating oils such as Mobil and Shell, which may be more familiar to everyone compared to white oil, are actually made by adding relevant functional additives to white oil.
White oil can be divided into industrial grade white oil, cosmetic grade white oil, medical grade white oil, food grade white oil, etc. Different categories of white oil also have different uses.
Industrial grade white oil is produced from base oil produced by hydrocracking as raw material, which is processed by deep dewaxing, chemical refining and other processes. It can be used in chemistry, textiles, chemical fibers, petrochemicals, electricity, agriculture, etc., and can be used in the production of PE, PS, PU and other products.
Food grade white oil is obtained by processing mineral oil as the base oil through deep chemical refining, edible alcohol extraction and other processes. Suitable for 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. It is used for food polishing, anti sticking, defoaming, planing, sealing, and can be used as a mold release agent for foods such as pasta, bread, biscuits, chocolate, etc. It can extend the storage and freshness period of wine, vinegar, fruits, vegetables, and canned food.
Medical grade white oil, suitable for the pharmaceutical industry, can be used as an oral medication for the production of mild diarrhea and as a defoamer for the production of penicillin.
Makeup grade white oil is obtained by deep refining hydrogenated raw materials. It is suitable for the cosmetics industry, and can be used as the base oil of hair cream, hair oil, lipstick, facial oil, skin care oil, sunscreen, baby oil, cream and other ointments and softeners. Makeup grade white oil can be used as an anti-static agent, softener, solvent, and hydrocarbon compound, which can increase moisture but cannot directly improve dry and damaged skin. There are different opinions on whether mineral oil can harm the skin, but it can be confirmed that impurities can cause allergies and acne, and those with already damaged or sensitive skin should avoid using it. Due to its color and characteristics, it is commonly used in white paste like medicines or skincare products. The higher the grade and purity of mineral oil, the safer it is for the skin. Makeup grade white oil needs to be tested to determine its purity, and cannot be distinguished by smell, vision, touch, or other means.
In the pesticide industry, it can be used to control pests such as citrus aphids, rust ticks, scale insects, and scale insects on loquat and bayberry trees. After processing, it is a good insecticide, and its mechanism of action is to produce suffocation by closing the stomata of adults or larvae. Especially for whiteflies, scale insects, and other smaller pests, the effect is very good and the price is low. It can be processed into emulsion or ready to use on-site. Due to its unique physical insecticidal principle of forming an oil film to seal the stomata of pests and causing them to suffocate and die, it has no resistance to long-term use. Not causing harm to natural enemies, thereby reducing medication costs. Long term use has no residue and can naturally decompose into water and easily degradable substances, without leaving any residue on crops.
Due to the increasing production of white oil products year by year, compared with other types of oil, white oil has a price advantage, so its application is also very extensive.
