Paraffin wax is obtained from petroleum by dewaxing light lubricating oil stocks; it was first produced commercially in 1867. It is used in candles, wax paper, polishes, cosmetics, sealing, and electrical insulators. It assists in extracting perfumes from flowers, forms a base for medical ointments, and supplies a waterproof coating for wood. In wood and paper matches, it helps to ignite the matchstick by supplying an easily vaporized hydrocarbon fuel. ]]></note></mads>
