History

In 1859, Robert Chesebrough, a chemist who formerly clarified kerosene from the oil of sperm whales, traveled to the oil fields in Titusville, Pennsylvania to research what new materials might be created from this new fuel. There he learned of a residue called rod wax that had to be periodically removed from oil rig pumps. The oil workers had been using the substance to heal cuts and burns. Chesebrough took samples of the rod wax back to Brooklyn, extracted the usable petroleum jelly, and began manufacturing a medicinal product he called Vaseline. The first known reference to the name Vaseline was by Chesebrough in his U.S. patent (U.S. Patent 127,568) in 1872. "I, Robert Chesebrough, have invented a new and useful product from petroleum which I have named Vaseline..." The name "vaseline" is said by the manufacturer to be derived from

''Wasser'' "water" + Greek έλαιον (''elaion'') "oil". Webster's Unabridged Dictionary (1913) Vaseline was made by the Chesebrough Manufacturing Company until the company, which merged with Pond's in 1955, was purchased by Unilever in 1987.

Uses

Vaseline can be used as a lubricant for metallic and plastic surfaces. Vaseline should never be used as a lubricant in sexual practices, as it may introduce infection-causing bacteria, damage latex condoms, and is not recommended for internal use. It can also be used as a moisture insulator for local skin conditions characterized by dry skin, such as

atopic dermatitis Atopic dermatitis (AD), also known as atopic eczema, is a long-term type of inflammation of the skin (dermatitis). It results in puritis, itchy, red, swollen, and cracked skin. Clear fluid may come from the affected areas, which often thickens o ...

and eczema in adults. Vaseline contains mineral oils. Unrefined mineral oils often contain adulterants including polycyclic aromatic hydrocarbons (PAHs), which can increase risk for certain forms of cancer when consumed orally. When used topically (as is recommended with Vaseline), dermal absorption of PAHs is insignificant. No link between topical petroleum jelly-based moisturizers and cancer has been found in large studies over many years.
