Vaseline, also known as petroleum jelly, is a semi-solid mixture of hydrocarbons. It is a byproduct of petroleum refining and can be produced in various grades, including pharmaceutical, cosmetic, and industrial. It is available in different grades, ranging from white petrolatum, which is highly refined and suitable for personal care products, to yellow or amber-colored petrolatum, which is less refined and used in industrial applications. Vaseline has a variety of uses in different industries, including as a lubricant, rust inhibitor, moisture barrier, and insulator. It is also commonly used in personal care products, such as lotions, ointments, and lip balms, due to its emollient and skin-protective properties.
