Petroleum jelly or petrolatum is a byproduct of the refining of petroleum, made from the residue of petroleum distillation left in the still after all the oil has been vaporized.
Vaseline is a well-known brand of petroleum jelly originally produced by Chesebrough-Pond's, Inc., and currently by Unilever.
Petroleum jelly was discovered by Robert Chesebrough in 1859 in Brooklyn, New York. Chesebrough was intrigued by the paraffin-like substance that stuck to the drilling rigs. The riggers hated the material because it caused the rigs to seize up, but they use it on cuts and burns because it helped them heal faster. Chesebrough bottled the petroleum jelly and took it back to his office where he tested it on himself.
He gave out free samples across New York and within six months he had twelve wagons distributing the product, under the trade name Vaseline, across the state. The term Vaseline was coined as a combination of the German word for water, Wasser (pronounced Vahser), and the Greek word for oil, elaion.
In 1872, Chesebrough patented (Template:US patent) the process of making petroleum jelly. The patent said that distillation by heat under vacuum involves less heat than without the vacuum, and yields a better quality of jelly. The product is then filtered through bone char. The patent says its uses include currying, stuffing, and oiling all kinds of leather. The finest grade of petroleum is also adapted for use as a pomade for the hair. It is also used for treating chapped hands or lips, and toenail fungus, and as a sexual lubricant, though being oil-based it can destroy the effectiveness of latex condoms. Petroleum jelly is known for its treatment of nosebleeds.
Robert Chesebrough lived to the age of 96 and claimed to have eaten a spoonful of Vaseline everyday. He was such a believer in Vaseline that during a bout of pleurisy, he had his body completely covered with it from head to toe. He soon recovered.de:Vaseline pl:Wazelina
