What is the difference between paraffin and paraffin oil?
May 04, 2018

Paraffin oil is a colorless, odorless mixture obtained from fractionation of crude oil, which is generally divided into crude paraffin oil and refined paraffin oil. Crude paraffin oil is considered to be a carcinogenic substance in medicine, and the "poisonous rice" that has caused nationwide stir has been mixed with crude paraffin oil, that is, industrial paraffin oil. Refined paraffin oil is often used as a moisturizing agent in skin care products.

The main component of paraffin is n-alkanes. The pure n-alkanes are colorless, odorless, transparent or translucent, and are exposed to the atmosphere for a long time and will not change color, but the commercial paraffin is not likely to be 100% n-alkanes, but contains a small amount of naphthenic, isomeric alkanes, aromatic hydrocarbons, unsaturated hydrocarbons, trace iron, sulfur, nitrogen and other inorganic compounds. Impurities, these impurities can give paraffin "paraffin taste", color (especially long exposure in the air color gradually deep), reduce the boiling point, more important is that the various flavors in the essence of the chemical changes or the chemical effects of various components lead to the change of aroma and the change and instability of color after flavoring.
