THE SCIENCE BEHIND THE SCENT

Inside the oil

8 constituents

An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.

About this composition

This hinoki essential oil record is anchored to a directly readable 2025 Shay and Company GC/MS report for steam-distilled Chamaecyparis obtusa oil from Taiwan and cross-checked against a 2024 Madar hinoki oil dossier that explicitly identifies the material as wood oil. The lot is compositionally distinct from the classic 1981 leaf profile, combining a large alpha-pinene fraction with cadinene and cadinol sesquiterpenes typical of hinoki wood oil.

What we're still learning · 3 data gaps

Good decisions start with knowing what is — and isn't — in the evidence.

Missing public source type: a directly viewable chemistry reference confirming CAS numbers for epi-alpha-cadinol, gamma-cadinene, tau-cadinol, alpha-muurolene, and delta-cadinol; those CAS fields remain null rather than guessed.
Odor intensity 50 is an archive normalization of AromaWeb's categorical 'Strength of Initial Aroma: Medium' for Taiwan hinoki rather than a native 0-100 measurement.
No public source with directly measured volatility-rate or tenacity-hour values was verified in this pass.
