The discovery of petroleum jelly Premium

On June 4, 1872, American chemist Robert Chesebrough was granted a patent titled “Improvement in products from petroleum”.

Whenever you had minor skin scrapes and burns, or just had to moisturise your face, hands, or other parts of the body, chances are that you probably used petroleum jelly. Yes, the folks around you or the elders at home probably referred to it with its brand name, but if you look at what it is made of, you will realise that it is petroleum jelly.

For one-and-a-half centuries now, petroleum jelly has played a pivotal part in skincare, be it to help with skin moisturising or healing. Also called petrolatum, petroleum jelly is a mixture of mineral oils and waxes that forms a semisolid jelly-like substance. Ever since American chemist Robert Augustus Chesebrough discovered it in the 19th Century, the product hasn’t changed much.

A British-born American chemist, Chesebrough owed his discovery to serendipity. He began his career as a chemist distilling kerosene from the oil of sperm whales. This role, however, soon turned obsolete with the discovery of petroleum in Titusville, Pennsylvania.

Now jobless, Chesebrough decided to travel to Titusville. He decided to research the new fuel to see what new materials might be created from it. Strolling around the oil field, Chesebrough came across something called rod wax, also known as petroleum jelly.

A byproduct of oil drilling, the jelly-like substance was cleaned off from the pumping equipment often. The workers told Chesebrough that it was largely a nuisance, except for one particular use. When someone had a cut or a burn, rubbing the wax on the injured area not only reduced the pain, but also allowed the injury to heal quickly.

Chesebrough set off back to his chemistry lab in Brooklyn with a batch of rod wax. He began experimenting and refining the process by which the wax was generated in order to come up with a solution that healed and protected the skin.

He spent the following years perfecting the technique of extracting a colourless, odourless form of petroleum jelly. By 1865, Chesebrough patented his purification method. This marked the beginning of triple-distilled petroleum jelly products, which remains the norm till this day.
