Vaseline is made of 100% pure petroleum jelly, which is a blend of mineral oils and waxes. This creates a semi-solid jelly that provides a protective barrier for the skin.
Breakdown of the Ingredients
-
Petroleum Jelly: The primary ingredient, also known as petrolatum, is a byproduct of oil refining. It's refined to be safe for cosmetic and medicinal uses.
-
Mineral Oils: These oils are highly refined and purified oils derived from petroleum. They contribute to the jelly's emollient properties, helping to soften and moisturize the skin.
-
Waxes: Waxes, also petroleum-derived, help to provide structure and consistency to the jelly, allowing it to maintain its form and creating a protective barrier.
History and Discovery
Robert Chesebrough discovered Vaseline in 1859. He noticed oil workers using a rod wax, a residue from drilling, to heal their skin. Chesebrough then refined and purified the substance, eventually patenting it as Vaseline. Its long history demonstrates its enduring ability to protect and moisturize skin.
