About
Methyldihydromorphine is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Methyldihydromorphine is a semisynthetic opioid analgesic derived from morphine, with pharmacological activity as a mu-opioid receptor agonist producing analgesia and CNS depression. Its CAS number 509-56-8 is specifically listed in EU Annex II (banned substances) under Regulation (EC) No 1223/2009, prohibiting its presence in cosmetic products. As a controlled substance with significant abuse potential and respiratory depression risk, it has no place in cosmetic formulations under any circumstances.
