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

A bicyclic terpenoid acetate with a woody-camphoraceous character. Oxidation-prone terpene scaffold — use with antioxidant protection.

Trimethylbicyclo-4-hepten-3-ylmethyl acetate (CAS 15103-33-0) is a norbornene-family bicyclic acetate with a woody, slightly camphoraceous fragrance profile. Related structurally to camphene/borneol chemistry. The ring double bond makes it moderately oxidation-prone, with peroxide formation as the main long-term concern. Used at trace levels in finished fragrance. RIFM/IFRA cover the broader bicyclic terpene family; public monograph-level data is limited.
