What is Oil?

In chemistry, oils are hydrophobic, viscous liquid mixtures of organic compounds — primarily long-chain hydrocarbons, triglycerides (fatty acid esters of glycerol), or mineral hydrocarbons. Petroleum (crude oil) is a complex mixture of hydrocarbons refined into fuels and feedstocks for the petrochemical industry. Vegetable and animal oils are triglycerides with unsaturated fatty acid chains; they are used as foods, biodiesel feedstocks, lubricants, and in the synthesis of soaps and surfactants.
