About

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

Ethylmethylthiabutene is a controlled opioid substance structurally related to dimethylthiambutene (a known drug of abuse). It has no history of use in cosmetic formulations and would not appear in EU cosmetics regulation databases. As a potent opioid analgesic, it would be subject to narcotics legislation and would be prohibited in cosmetic products under Regulation (EC) No 1223/2009 general safety principles, as substances with pharmacological activity are excluded from cosmetic use.

Known concerns

  • Potent opioid agonist — not a cosmetic ingredient
  • Controlled substance under narcotics regulations
  • Prohibited in cosmetic products under EU general safety provisions
