Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Methyl-methylbicycloheptenyl-pentenol is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This is a complex polycyclic sesquiterpene-type unsaturated alcohol with a bicycloheptenyl core. The hazard classification H319 indicates serious eye irritation potential, and H411 denotes chronic aquatic toxicity — requiring disposal precautions. The EU's IFRA standards restrict sesquiterpene alcohols with unsaturated structures due to sensitisation and oxidation concerns. Formulators must ensure this material stays within IFRA-recommended limits and includes appropriate labelling.

Skin benefits

  • Valuable fragrance component for complex woody/earthy compositions
  • Contributes to long-lasting fragrance character

Known concerns

  • H319 serious eye irritant
  • H411 chronic aquatic toxicity — environmental hazard
  • Unsaturated polycyclic structure — oxidation products may be sensitisers
  • Must comply with IFRA standards for sesquiterpene fragrance materials
