WebWhat is Liquid Paraffin? Liquid paraffin is a very highly refined mineral oil used in cosmetics and medicine. Mineral oil is a clear, odorless oil derived from a mineral source, typically a distillate of petroleum. It is the by-product of refining crude oil to make gasoline and other petroleum products. The first unit operation (after being desalinated) in a petroleum refinery is the crude oil distillation unit. The overhead liquid distillate from that unit is called virgin or straight-run naphtha and that distillate is the largest source of naphtha in most petroleum refineries. The naphtha is a mixture of many different hydrocarbon compounds. It has an initial boiling point (IBP) of about 35 °C and a final boiling point (FBP) of about 200 °C, and it contains paraffins, naphthenes (cyclic paraffins) and aromatic …
