This chemical (also called spirit of turpentine, wood turpentine, gum turpentine) is a fluid obtained by the distillation of resin obtained from trees, mainly pine trees. Composed of terpenes, mainly the monoterpenes alpha-pinene and beta-pinene. This has a potent odor similar to that of nail polish remover. Although, sometimes known colloquially as turfs, but this more often refers to turpentine substitute (or mineral turpentine). This chemical is not a pure substance but a complex mixture of terpenes, particularly large proportion of pinene (bicyclic monoterpenic hydrocarbon), a compound from which camphor is manufactured.
