White oil typically refers to crude oil that has been extracted and initially processed, a natural mineral product buried underground. Unrefined oil extracted through exploration and drilling is also called this. In normal temperatures, the refined finished product is known as petroleum products.
White oils are typically categorized by the purity of their saturated hydrocarbons, with common types including industrial white oil, suitable for fiber and aluminum processing, rubber plasticizers, and other oils for various uses. Different categories of white oil have different applications. Industrial-grade white oil is used in industries such as fiber synthesis, as a lubricant, solvent, and coolant during textile production, making fibers and fabrics soft and glossy. It also serves as a wetting agent, solvent, and lubricant in the processing of synthetic resins and plastics. It is also suitable for lubricating textile machinery, precision instruments, and as sealing oil for compressors. Food-grade white oil is used in food applications, including anti-sticking, defoaming, sealing, polishing, and food machinery. It extends the storage life of wine, vinegar, fruits, vegetables, or canned goods. Additionally, it is used as a base oil for lubricating laxatives, ointments, and pharmaceuticals, as a mold release agent for tablets and capsules, and for anti-corrosion and lubrication of surgical instruments and pharmaceutical machinery.

Industrial-grade white oil, derived from base oils produced through hydrocracking and processed with deep dewaxing and chemical refining, is suitable for use in industries such as chemicals, textiles, chemical fibers, petrochemicals, electricity, and agriculture. It is also applicable in the production of PE, PS, PU, etc.

White oil is a colorless, transparent liquid with no odor. It is a mixture of liquid hydrocarbons, primarily composed of a mixture of n-alkanes and iso-alkanes with carbon numbers ranging from C16 to C31. It is produced from the high-boiling fraction (i.e., lubricating oil fraction) of petroleum after undergoing processes such as dewaxing, carbonization, neutralization, and activated clay refining. As a widely used oil-soluble raw material, white oil is often used to assist in demolding, enhance product luster, and is commonly applied in rubber products. It can also serve as a lubricant in stamping molds.

Food-grade white oil: It is based on mineral oil, then processed through deep chemical formulation and refining. Widely used in food applications such as oil and grain processing, fruit and vegetable processing, dairy product processing, and bread slicing machines, mainly for purposes like polishing, anti-sticking, smoothing, and sealing on various foods. In addition, it can also be used as an additive in foods like pasta, bread, biscuits, and chocolate, extending their shelf life and preservation.
