About

A gold complex of N-acetylmethionine amino acid with restricted cosmetic use in the EU, listed under Annex II/296.

Gold Acetylmethionate is listed in EU CosIng with restriction II/296, indicating use is allowed only under specified conditions (typically max concentration or specific product categories). Gold as a metal has limited systemic absorption data, but its complexes introduce additional regulatory scrutiny. The restriction designation under Annex II/296 limits its use in leave-on and certain rinse-off applications.

Skin benefits

  • Anti-inflammatory properties claimed by manufacturers
  • Antioxidant activity attributed to methionine moiety

Known concerns

  • EU Annex II/296 restriction limits cosmetic use

  • Potential for skin discoloration with prolonged use
