About
A bicyclic unsaturated terpene alcohol with no classified hazards, used in fragrance compositions for its fresh, woody, and green character.
Trimethylbicyclo-3-hepten-2-ol is an unsaturated bicyclic monoterpene alcohol. No CLP hazard classifications apply to this ingredient. It is not listed in EU cosmetic regulation Annexes, meaning it can be used without formal restriction. The bicyclic structure (norbornane-type) with a double bond gives it a distinctive scent profile. As with all fragrance materials, IFRA guidelines establish safe use concentrations.
