What is petrolatum USP?

Petrolatum USP, also known as petroleum jelly or mineral jelly, is a semi-solid mixture of hydrocarbons derived from petroleum. It is designated as "USP" (United States Pharmacopeia) to indicate that it meets specific quality standards for pharmaceutical and medical use. Commonly used as a topical ointment, it acts as a moisturizer and barrier to protect the skin from moisture loss and external irritants. Its applications extend to personal care products, cosmetics, and various medicinal formulations.
