Gasoline
Gasoline is a petroleum-derived liquid mixture consisting primarily of hydrocarbons, used as fuel in internal combustion engines. Before internal combustion engines were invented in the mid-1800s, gasoline was sold in small bottles as a treatment against lice and their eggs. This treatment method is no longer common because of the inherent fire hazard and the risk of dermatitis. Gasoline is produced in oil refineries. Material that is separated from crude oil via distillation, called natural gasoline, does not meet the required specifications for modern engines, but will form part of the blend.
The bulk of a typical gasoline consists of hydrocarbons with between 5 and 12 carbon atoms per molecule. Many of these hydrocarbons are considered hazardous substances and, in the United States, are regulated by the Occupational Safety and Health Administration.
