A bicyclic camphor-like hydrocarbon — a terpene fragrance with normal IFRA controls.
Trimethylbicycloheptane (e.g. 2,2,3-trimethyl- / bornane-type bicyclic terpenes) is a saturated bicyclic hydrocarbon related to norbornane and camphane skeletons. It is used as a fragrance ingredient with fresh, pine/camphoraceous notes. Like other terpene hydrocarbons it is volatile and flammable as a neat material, and IFRA/RIFM govern its use in finished products. Sensitization concerns arise primarily from oxidation products over time, which is a general terpene-fragrance consideration. Cosmetic use at typical perfumery concentrations is considered acceptable.
