Vaseline

Vaseline is a brand of petroleum jelly produced by Unilever. It consists of petrolatum, a semi-solid mixture of hydrocarbon molecules derived from petroleum. The product is used as an occlusive skin protectant and moisturizer, forming a barrier that reduces water loss and protects irritated or dry skin. It is also used as a lip balm, to soothe minor chafing, and on minor cuts or burns to protect the area while healing. In cosmetics, Vaseline serves as a thickener and emollient; in industrial settings, petrolatum is used as a lubricant and rust-preventive grease.

The substance was discovered in 1859 by chemist Robert Chesebrough, who marketed it as Vaseline in the United States in the 1870s. The Vaseline brand name has become a common reference to petrolatum, though petrolatum itself remains the generic term.

Pure Vaseline products are typically formulated as petrolatum, sometimes with additional ingredients in variants such as Intensive Care formulas that add moisturizers or fragrance. The core component, petrolatum, is largely inert and non-irritating for most individuals, but some people may experience dermatitis or sensitivity. As with any topical product, it should be used externally only, kept away from heat or flames, and not ingested. It is not a cure for medical conditions and should be used according to product directions or medical advice.
