Mineral Oil Buono Emolliente Idratare Mineral Oil description Clear, odorless oil derived from petroleum that is widely used in cosmetics. Despite mineral oil’s association with petroleum and the hype that it’s bad for or ages skin, keep in mind that petroleum is a natural ingredient derived from the earth. Once it’s purified to become mineral oil USP (cosmetics- and pharmaceutical-grade mineral oil), it has no resemblance to the original petroleum and isn’t a source of contaminants.Cosmetics-grade mineral oil and petrolatum are considered the safest, most non-sensitizing moisturising ingredients ever found. Mineral oil and petrolatum are known to be efficacious in skin replenishing and are also among the most effective, established moisturising ingredients available. The mineral oil in skincare products is certified as either USP (United States Pharmacopeia) or BP (British Pharmacopeia). It’s completely safe, soothing, non-sensitizing, and perfectly beneficial for skin.
