Petroleum jelly, vaseline, petrolatum or soft paraffin  is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties. Its folkloric medicinal value as a "cure-all" has since been limited by better scientific understanding of appropriate and inappropriate uses (see Uses below) However, it is recognized by the U.S. Food and Drug Administration (FDA) as an approved Over-The-Counter (OTC) skin protectant and remains widely used in cosmetic skin care. It is commonly referred to as Vaseline as a genericized trademark.
The raw material for petroleum jelly was discovered in 1859 in Titusville, Pennsylvania, United States where it was stuck to some of the first oil rigs in the U.S. The workers disliked the paraffin like material because it caused the rigs to seize up, but they used it on cuts and burns because it hastened healing.
Robert Chesebrough, a young chemist whose previous work of distilling fuel from the oil of sperm whales had been rendered obsolete by petroleum, went to Titusville to see what new materials had commercial potential. Chesebrough took the unrefined black "rod wax", as the drillers called it, back to his laboratory to refine it and explore potential uses. Chesebrough discovered that by distilling the lighter, thinner oil products from the rod wax, he could create a light-colored gel. Chesebrough patented the process of making petroleum jelly (U.S. Patent 127,568) in 1872. The process involved vacuum distillation of the crude material followed by filtration of the still residue through bone char.
Chesebrough traveled around New York demonstrating the product to encourage sales by burning his skin with acid or an open flame, then spreading the ointment on his injuries and showing his past injuries healed, he claimed, by his miracle product.
He opened his first factory in 1870 in Brooklyn, United States. The brand name "Vaseline" has been anecdotally claimed to be from the German word for water, wasser (pronounced vahser), and the Greek word for oil, elaion, but this is unconfirmed.
Petrolatum is a flammable, semi-solid mixture of hydrocarbons, having a melting-point usually ranging from a little below to a few degrees above 100°F (37°C). It is colorless, or of a pale yellow color (when not highly distilled), translucent, and devoid of taste and smell when pure. It does not oxidize on exposure to the air, and is not readily acted on by chemical reagents. It is insoluble in water. It is soluble in chloroform, benzene, carbon disulfide and oil of turpentine.
There is a common misconception (resulting from the similar feel they produce when applied to human skin) that petroleum jelly and glycerol (glycerine) are physically similar. While petroleum is a non-polar hydrocarbon hydrophobic (water-repelling) and insoluble in water, glycerol (not a hydrocarbon but an alcohol) is the opposite: it is so strongly hydrophilic (water-attracting) that by continuous absorption of moisture from the air, it produces the feeling of wetness on the skin, similar to the greasiness produced by petroleum jelly. The feeling is similar, but petroleum jelly repels water, and glycerine attracts it.

Depending on the specific industry the petrolatum is used for, the petrolatum may be USP (United States Pharmacopeia) grade. This pertains to the processing and handling of the Petrolatum so it is suitable for cosmetic and personal care applications.
Chesebrough originally promoted Vaseline primarily as an ointment for scrapes, burns, and cuts, but physicians have shown that Vaseline has no medicinal effect or any effect on the blistering process, nor is it absorbed by the skin. Vaseline’s effectiveness in accelerating wound healing stems from its sealing effect on cuts and burns, which inhibits germs from getting into the wound and keeps the injured area supple by preventing the skin's moisture from evaporating. "Vaseline First Aid Petroleum Jelly" brand, (which contained phenol to give the jelly additional anti-bacterial effect), has been discontinued.
However, after becoming a medicine chest staple, consumers began to use Vaseline for myriad ailments and cosmetic uses, including: chapped hands or lips, toenail fungus, nosebleeds, diaper rash, chest colds, and even to remove makeup or stains from furniture. It is even used as trout bait. There are uses for it for pets, including stopping fungi from developing on aquatic turtles' shells and to keep cats from making messes when they cough up furballs. In the first part of the twentieth century, petrolatum, either pure or as an ingredient, was also popular as a hair pomade. When used in a 50/50 mixture with pure beeswax, it makes an effective moustache wax.
It was also used to shine heaters and slow combustion stove tops.
Most petroleum jelly today is consumed as an ingredient in skin lotions and cosmetics. Although petrolatum is less expensive than glycerol, the most common active lubricating ingredient in skin lotion, it is not used in expensive lotions because it is not absorbed into the skin resulting in a greasy feel.
Petroleum jelly was formerly used as a way to pitch a spitball in baseball. Although the pitch was banned in 1920, pitchers sometimes throw "the spitter" surreptitiously.
It can also be used as tinder when coated on cotton balls. The combination can easily be ignited by a fire starter, burning fiercely for several minutes, and the petroleum keeps the cotton from getting wet.
It can be used as a quick method of shining shoes, when spread evenly onto the surface to create a shiny layer. A con to this is that the layer of jelly atracts dirt.
Dangerous uses to avoid
As the substance became more common in households, it began to be used for a number of medical purposes, some of which medical science has shown to be dangerous or damaging.
- It should not be used on fresh burns of any kind, including sunburn. Petrolatum traps heat inside, worsening burns. After heat has dissipated, however, it can serve as a dressing for minor burns to soothe later pain.
- Nasal congestion or dryness
- It may immobilize the cilia in the nose, impeding its ability to clean incoming airTemplate:Fix/category. As well, if small particles of petrolatum are inhaled from the nose, they may deposit in the lungs and lead to a condition called lipid pneumonia.
- Sex with latex condoms
- Since petroleum is a kind of oil, it interferes with the structure of latex. Using petroleum jelly with latex condoms weakens the material increasing the chance of rupture, and thereby the chance of conceiving or spreading sexually transmitted infections.
