About

2-Ethoxymethoxy-P-Phenylenediamine is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

This PPD derivative carries an ethoxymethoxy substituent (-O-CH2-CH2-O-CH3), placing it within the class of alkylether-modified p-phenylenediamine hair dye intermediates. The EU Cosmetics Regulation Annex III (part 2) imposes specific concentration limits (typically expressed as free base) and requires these compounds to be labelled with sensitization warnings when present above threshold concentrations in oxidative hair dye products. The sensitization potential is inherent to the aromatic amine structure.

Known concerns

  • Skin sensitizer (aromatic amine hair dye class)
  • EU Annex III restricted - specific limits apply
  • Mandatory sensitization labelling required
