Mineral Oil

OKemollient

An emollient that forms a protective barrier on the skin to prevent moisture loss.

What does Mineral Oil do for skin?

Mineral oil functions primarily as an occlusive emollient by forming a hydrophobic, non-permeable film on the skin's surface. This physical barrier effectively reduces transepidermal water loss (TEWL) by preventing the evaporation of water from the stratum corneum. By trapping existing moisture, it indirectly enhances skin hydration and supports the skin barrier function, leading to a softer, smoother feel without interacting with specific cellular receptors or biochemical pathways within the skin.

Typical concentration: Mineral oil is a versatile ingredient, often used as a base or solvent. Its concentration can range from 1-10% in light emulsions to 50-100% in anhydrous products like petrolatum-based ointments or pure mineral oil products for massage or cleansing.

Is Mineral Oil safe?

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed mineral oil as safe for use in cosmetics. Highly refined cosmetic-grade mineral oil is generally non-irritating, non-sensitizing, and non-comedogenic.
