Avoid

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

A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Pyridine and its alkyl derivatives (CAS 68391-11-7) are aromatic nitrogen heterocycles. If contaminated with more than 0.1% w/w benzene, this raw material falls under EU Annex II prohibition for cosmetic use. Pyridine compounds are used in industrial contexts; their cosmetic use is highly unusual and would require separate safety assessment. The benzene contamination threshold is the primary regulatory trigger here, consistent with the EU's approach to all benzene-contaminated streams.

Known concerns

  • EU Annex II — benzene contamination (>0.1% prohibited)
  • Known human carcinogen (benzene)
  • Pyridine compounds of independent concern
