Mineral oil

A mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum.
Most often, mineral oil is a liquid by-product of refining crude oil to make gasoline and other petroleum products. This type of mineral oil is a transparent, colorless oil composed mainly of alkanes and cycloalkanes, related to petroleum jelly. It has a density of around 0.8 g/cm3.
The hydrocarbon contamination of soil and water by the spillage or leakage of petrol, diesel, or lubricants is one of the most common forms of environmental pollution. Standards e.g. EN-ISO 9377-2 or ISO 16703 have been developed for the determination of the mineral oil content in water and soil by gas chromatography.
