Cosmetic Grade Petroleum Jelly
Cosmetic Grade Petroleum Jelly is a semi-solid mixture of highly refined hydrocarbons derived from petroleum. It is white or off-white in color, smooth in texture, and virtually odorless and tasteless. Widely used in skincare and personal care products, it acts as an occlusive agent that forms a protective barrier on the skin to lock in moisture and aid in healing dry, cracked, or irritated skin. It is used in lip balms, moisturizers, baby care products, hair pomades, and other topical formulations. Cosmetic grade petroleum jelly undergoes extensive purification to remove impurities, ensuring it is safe for use on the skin and meets international cosmetic safety standards.
