About

4-Nitrocarbazole is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

4-Nitrocarbazole is a nitroaromatic compound based on the carbazole ring system, bearing a nitro group at the 4-position. It is not listed in EU Regulation 1223/2009 Annexes, meaning it is not authorized for cosmetic use in Europe. The nitro group on an aromatic ring system raises concerns about potential genotoxicity and carcinogenicity, similar to other nitroaromatic compounds. Its PubChem CID (151524) indicates it has been studied in chemical databases, but it lacks the safety dossier required for cosmetic ingredient authorization.

Known concerns

  • Not authorized for cosmetic use in EU (not in any annex)
  • Nitroaromatic structure - potential genotoxic concern
  • No safety assessment available for cosmetic application
