About

Metazocine is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Metazocine is a morphinan-type opioid agonist with potent analgesic properties. In the EU, substances with significant pharmacological activity that are not approved for cosmetic use fall under the Cosmetics Regulation's prohibition on substances not authorized for topical application. It is not listed in CosIng and would be considered a pharmaceutical substance with no demonstrated safe use in cosmetic formulations.

Known concerns

  • Prohibited in cosmetic products — not authorized under EU Cosmetics Regulation
  • Potent opioid receptor agonist with CNS effects
  • No safety assessment available for topical cosmetic use
  • May be subject to drug scheduling in many jurisdictions
