White Oil 26 CAS NO.8042-47-5
Products Description
- White oil，usually refers to white mineral oil. It is a special deep refined mineral oil. White oil is colorless, odorless, chemically inert, and has good light stability. The basic composition of white oil is a saturated hydrocarbon structure. 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.
- White oil (mineral oil) is called white mineral oil or white oil in some fields. Commonly used are industrial-grade white oil, cosmetic-grade white oil, medical-grade white oil, and food-grade white oil. Different types of white oil have different uses.
- Cosmetic grade white oil is obtained after deep refining with hydrogenated raw materials. It is suitable for the cosmetic industry and can be used as the base oil of ointments and softeners such as hair cream, hair oil, lipstick, facial oil, skin care oil, sunscreen oil, baby oil, vanishing cream, etc.
- Cosmetic grade white oil can be used as an antistatic agent, emollient, solvent, solvent, and hydrocarbon, which can increase the feeling of moisture, but it cannot directly improve dry and damaged skin. There are different opinions as to whether mineral oil harms the skin, but it is certain that the impure mineral oil can cause allergies and acne-causing properties, and people who are already suffering from damage or sensitive skin should avoid using it. Because of its color and characteristics, it is often used in white cream medicines or skin care products.
Product Feature
White oil is a colorless translucent oily liquid with no or almost no fluorescence. It is odorless and tasteless when cold. It has a slight petroleum odor when heated. It is insoluble in water and ethanol, soluble in volatile oil, and miscible in most non-volatile oils. Light, heat, acid, etc. are stable, but long-term exposure to light and heat will slowly oxidize.
Narrow fraction, strong dissolving power and good volatility;
- The saturated hydrocarbon content is greater than 99%, and the product has good stability
- Low sulfur, low aromatic, non-toxic, tasteless
- It is colorless, tasteless, non-toxic, non-flammable, non-explosive, has excellent stability, light resistance, chemical stability, does not corrode fiber textiles, has no irritation to the skin, and has good affinity.
