1.White Petroleum Jelly is completely purified mixture of semi-solid hydrocarbons obtained from by-product of petroleum refining, and wholly or nearly decolorized. Petroleum Jelly is odorless and colorless and it has an inherently long shelf life. These qualities make Petroleum Jelly a popular ingredient in skincare products and cosmetics.
2.Petroleum Jelly serves two functions: Firstly, it protects skin from the effects of weather and exposure. Secondly, it forms an occlusive barrier to the natural water loss of our skin.
