THE SCIENCE BEHIND THE SCENT
Inside the oil
An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.
About this composition
This record is batch-specific and anchored to the public Hermitage Essential Oils product page for the 2026 Vanuatu sandalwood 'Mushroom' lot, which explicitly states 46.7% alpha-santalol and 16.8% beta-santalol and describes a mushroom-tinged sandalwood profile with strong buttery, woody, nutty, and forest-floor facets. The underlying species is Santalum austrocaledonicum from Vanuatu heartwood, a sandalwood type known for substantial tree-to-tree variation in alpha- and beta-santalol content across Vanuatu populations. The remaining minor sesquiterpene alcohol composition (bergamotol, lanceol, epi-beta-santalol) is reused from a same-species Santalum austrocaledonicum GC/MS certificate of analysis (New Caledonia lot), and (Z)-beta-curcumen-12-ol and (Z)-nuciferol are added as species-confirmed major constituents per Page et al. (2010), with proxy percentages drawn from a same-genus Santalum spicatum GC/MS report because no public batch-specific percentage exists for these two markers in S. austrocaledonicum.

What we're still learning · 4 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- The only publicly disclosed quantitative composition on the reviewed batch page was alpha-santalol and beta-santalol. A public GC-MS or COA for this exact 2026 Vanuatu batch would be needed to extend the constituent list with additional verified percentages.
- The bergamotol, lanceol, and epi-beta-santalol rows are reused from a different Santalum austrocaledonicum lot (New Caledonia) rather than this exact Vanuatu batch, and the (Z)-beta-curcumen-12-ol and (Z)-nuciferol percentages are proxied from Santalum spicatum because no public S. austrocaledonicum percentage was located, so all five supporting rows should be treated as species/genus-level estimates rather than batch-verified values.
- max_dermal_pct 10 is taken from the product page's explicit 'IFRA 51: 10.00% in finished product (Cat. 4)' statement rather than a broader species monograph.
- No directly published 0-100 odor score was located; odor_intensity 90 is an archive normalization of the supplier's language describing strong diffusion, substantivity, and a highly characterful mushroom-buttery sandalwood profile.
