Decoding Petroleum Jelly: Is It Really Oil-Free?
Petroleum jelly, also known as Vaseline or petrolatum, is a semi-solid mixture of mineral waxes and oils. Despite its name, it is not entirely oil-free but primarily composed of microcrystalline wax obtained from petroleum. With up to 60% mineral wax content, petroleum jelly has various uses including medical applications, skin protection, and industrial purposes. It provides an effective barrier against moisture loss and environmental extremes but may cause clogged pores or comedones when used excessively.
