Caution

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Nitrous Oxide is a cosmetic ingredient. Exercise caution due to limited available safety data.

Nitrous oxide (CAS 10024-97-2), commonly known as laughing gas, is used medically as an analgesic and anaesthetic. It has no recognized cosmetic function and is not listed in EU Regulation 1223/2009 Annexes II, III, IV, or VI, meaning it is not an authorised cosmetic ingredient. Its use in food (as propellant) is regulated separately. The compound is a greenhouse gas and has mild recreational abuse potential. From a cosmetic safety perspective, it is not appropriate for topical application and would be considered an unauthorized ingredient if present in EU cosmetic formulations.

Known concerns

  • No cosmetic function authorised in EU
  • Not listed in any EU cosmetic annex
  • Medical anaesthetic with no topical cosmetic application
  • Greenhouse gas
