Paraffin is a mixture of solid saturated hydrocarbons extracted from crude oil, which has a uniform appearance and is free of any foreign substances and is solid at room temperature. Melted paraffin should be a clear liquid free of water, foreign particles and visible impurities. In chemistry, paraffin is usually associated with the word alkane, which has the chemical formula CnH2n+2.
Paraffin is in two forms, solid and liquid.
Paraffin has a variety of practical uses in industries that range from medicine and agriculture to cosmetics. While the very first usage of paraffin dates back to the 19th century as paraffin wax in candles, the oil has since found use in many other forms. Paraffin is commonly used as a fuel for jet engines and rockets, as well as a fuel or fuel component for diesel and tractor engines.
