a description
Pure petroleum jelly is a semi-solid, oily cosmetic ingredient derived from highly purified petroleum hydrocarbons through rigorous refining processes to remove impurities. It is characterized by its smooth texture and excellent ability to form a protective barrier on the skin's surface, making it one of the most commonly used ingredients in protective and moisturizing products.
Petrolatum acts cosmetically as an occlusive agent, helping to reduce moisture loss from the skin's surface without penetrating it. It possesses excellent chemical stability, does not oxidize easily, and is non-reactive and cosmetically inert, making it suitable for sensitive skin and highly tolerable in various formulations.
