Kerosene, also known as lamp oil, is a combustible hydrocarbon liquid widely used as a fuel in industry and households. Its name derives from Greek:κηρός (keros) meaning wax, and was registered as a trademark by Abraham Gesner in 1854 before evolving into a genericized trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term "kerosene" is common in much of India, Canada, the United States, Argentina, Australia and New Zealand.
