Most commonly known as kerosene, this substance also goes by the name paraffin, lamp oil, or coal oil depending on the region of the world in which it is being sold. Kerosene is a thin, clear liquid formed from hydrocarbons which are obtained from the distillation of petroleum. It is miscible in petroleum solvents, but immiscible in water. It has numerous uses in both industrial and consumer settings, and is sometimes spelt kerosine in scientific and industrial usage. It derives its name from the Greek word keros, which means wax. Kerosene is used as jet fuel and rocket fuel, and is a common source of fuel for cooking and lighting. In some countries where the price is subsidized, kerosene is also used to power outboard motors on smaller fishing boats. Worldwide, kerosene consumption totals to about 1.2 million barrels per day. Kerosene is primarily used in industry as both a solvent and as a lubricant.
