About
A bicyclic sesquiterpene alcohol used as a fragrance ingredient, giving floral and woody notes to perfumes and scented cosmetic products.
2-Dimethylbicyclohept-2-ylidene ethanol (also known as Patchi alcohol or a derivative of norbornane chemistry) is a bicyclic sesquiterpene alcohol functioning as a fragrance ingredient. It carries EU CLP hazard classification H319 (causes serious eye irritation). It is not listed in EU Annexes II or III. This bicyclic structure is consistent with many natural sesquiterpene alcohols found in essential oils. Used at trace fragrance levels, systemic exposure is minimal, and irritation risk is primarily limited to direct eye contact.
