Moderate

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

A hair dye intermediate that is a known skin sensitizer and requires strict concentration limits in cosmetic formulations.

This aromatic amine is used as a precursor in oxidative hair dye formulations. The EU Cosmetics Regulation (EC 1223/2009) Annex III restricts its use in hair dye products due to well-documented skin sensitization potential. While permitted at low concentrations with appropriate warnings, it remains under regulatory scrutiny as a potential respiratory sensitizer as well.

Known concerns

  • Known skin sensitizer (H317 - May cause allergic skin reaction)
  • Respiratory sensitization potential
  • Restricted in EU Annex III for hair dye use only
