Lanolin Anhydrous USP Grade is a natural, high quality purified lanolin derived from sheeps wool. Lanolin is one of the best substances for use on delicate, dry or chapped skin as it provides a protective barrier on the skin and helps to hold moisture into the skin. It is often a key ingredient in chapsticks, creams, shaving lotions, and skin moisturizers and commonly used to soothe rashes, minor burns and abrasions.
