About

Ethanol, 2-((4- Amino-2-nitrophenyl)amino)- is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This nitro-phenylenediamine derivative is used as a coupling agent in oxidative hair colourant systems to produce brown and grey shades. EU Regulation (EC) No 1223/2009 Annex III restricts its maximum concentration to 3.0% in hair dye preparations after mixing with oxidative agents. Nitro aromatic compounds may raise concerns regarding potential sensitisation and photosensitisation, though this specific compound has limited published safety data in cosmetic contexts.

Known concerns

  • EU Annex III restricted (3.0% max in hair dyes)
  • potential skin sensitiser
  • nitro-aromatic structural concern
