An inert, colorless gas used as a propellant and blanketing agent in aerosol and pressurized cosmetic formulations to prevent oxidation. Inherently non-toxic and does not penetrate skin.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
