What it is
This ingredient is a clear, odorless, highly refined oil obtained from petroleum and purified for cosmetic use. It forms an occlusive layer that softens skin and helps reduce moisture loss, and it can also serve as a carrier for oil-soluble ingredients. In sunscreens it contributes to a smooth, spreadable texture and a conditioned feel.
Safety & warnings
Cosmetic-grade mineral oil is highly refined, chemically inert, and widely regarded as well tolerated and non-sensitizing; it is not a recognized fragrance allergen. It is occlusive and can feel heavy, and although cosmetic-grade material is considered low risk, very acne-prone users sometimes prefer lighter emollients.
Origin & sourcing
Mineral-derived: a highly refined and purified fraction of petroleum, processed to cosmetic grade.
