Safety Profile
GENERALLY SAFEWhat Does cis-2-tert-Butylcyclohexan-1-ol Smell Like?
Opens with a crisp, slightly camphoraceous freshness reminiscent of crushed pine needles. The heart reveals a smooth woody character with subtle floral undertones, like the scent of a cedar chest lined with dried lavender. Dry-down is clean and persistent, leaving a refined musk-amber impression with excellent tenacity on skin.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used as a core woody-modifier to create an ultra-clean modern forest accord, combining with norlimbanol for razor-sharp diffusion.
Provides the crisp herbal foundation in this futuristic fougère, pairing with ambroxan for a high-tech barbershop effect.

Chemistry, Properties & Perfumer Guide
The Chemistry
A monoterpenoid alcohol with a rigid cyclohexane backbone and bulky tert-butyl group at the 2-position. The cis configuration creates distinct steric constraints that influence its odor profile. Synthesized via hydrogenation of corresponding ketone precursors or through Grignard reactions. The tert-butyl group provides exceptional stability against oxidation compared to similar cyclohexanol derivatives.
