In many languages, the word "vaseline" is used as
generic for petroleum jelly; in
Portugal, the Unilever products are called Vasenol, and in
Brazil and some
Spanish-speaking countries, the Unilever products are called Vaselina.
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.[4]
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
GermanWasser "water" +
Greek έλαιον (elaion) "oil".[5]
Vaseline can be used as a lubricant for metallic and plastic surfaces. Vaseline should never be used as a
sexual lubricant, as it may introduce infection-causing bacteria,[6][7][8] damage latex condoms,[9][10] and is not recommended for internal use.[11] It can also be used as a moisture insulator for local skin conditions characterized by dry skin, such as
atopic dermatitis and
eczema.[12]
Topical application
As a petrolatum product, Vaseline is used as a
topicalmoisturizer which assists with skin water retention by acting as an occlusive agent that prevents
evaporation of water from the
stratum corneum (outermost skin layer) and seals out external water.[11][12] Vaseline is intended for external use only, and is not recommended for deep skin cuts or punctures, animal bites, or serious burns.[12] Topical petrolatum products like Vaseline are used to manage and relieve
atopic dermatitis and
eczema in adults.[11][13]
Vaseline contains
mineral oils.[12] Unrefined mineral oils often contain adulterants including
polycyclic aromatic hydrocarbons (PAHs), which can increase risk for certain forms of cancer when consumed orally.[14] When used topically (as is recommended with Vaseline), dermal absorption of PAHs is insignificant.[15] No link between topical petroleum jelly-based moisturizers and cancer has been found in large studies over many years.[16]
