History
In 1859, a 22-year-old chemist named Robert Chesebrough   traveled to Titusville, a small town in Pennsylvania where oil had recently been discovered. While conducting research in an oil well , he   noticed rumors among the workers about a jelly-like substance that regularly enters various equipment components and disrupts the performance of the parts.

While observing the oil workers, Robert Cheesebro noticed that the workers smeared their skin with oil residues on the drill. The reason for this was that Vaseline would help heal their cuts and burns.

He found this jelly substance was a  by-product of the drilling process, it has healing properties for the skin. Cheesebrough took some of this amazing substance to the lab to experiment on. His investigations finally led to the creation of the famous and widely used product Vaseline.

 Petroleum jelly or petrolatum, known  as  Vaseline, is a mineral oil that was discovered by Robert Augustus Chisbury in 1859. Vaseline is actually a combination of paraffin, microcrystalline wax and minerals.

Vaseline is also used as a lubricant and  is also used  as a   skin tissue  moisturizer in the production of creams and lotions . Vaseline can protect skin from wounds and burns.
