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

About this composition

This record is species-specific to Australian sandalwood, Santalum spicatum, not Australian-grown Santalum album. The constituent table is anchored to a directly readable Plant Therapy / PhytoChemia GC-MS report for Australian-origin S. spicatum and corroborated by AromaWeb's dedicated Australian sandalwood profile, which notes that Australian sandalwood generally contains about 24-34% total santalol isomers and is rich in additional sesquiterpenols.

Traditional & reported uses

These uses reflect the profile's reported traditions and literature. They are not established treatment recommendations.

traditionally used in aromatherapy for grounding, meditative, and calming effects
reported to support restful sleep in evening blends
used in perfumery as a smooth, woody, slightly dry base note
traditionally associated with skin-care blends for its soothing reputation
used in massage blends to support a relaxed, centered mood

What we're still learning · 5 data gaps

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

No public source reviewed in this pass published a native 0-100 odor score; `odor_intensity` 40 is a normalization of AromaWeb's 'Mild to Medium' strength-of-initial-aroma band for Australian sandalwood.
The public Australian Sandalwood AromaWeb profile reports no known hazards but does not publish a numeric leave-on dermal ceiling; `max_dermal_pct` 8 is therefore taken from The Good Scents Company's public IFRA-linked usage recommendation for Santalum spicatum fragrance concentrate, not from a directly readable aromatherapy-specific dermal monograph.
No public source reviewed in this pass published a verified numeric volatility rate or tenacity-hour span for Australian sandalwood oil.
Public open CAS confirmation for (Z)-Nuciferol, (Z)-beta-Curcumen-12-ol, epi-alpha-Bisabolol, and (Z)-gamma-Curcumen-12-ol was not verified in this pass, so those CAS fields remain null rather than guessed.
Closure reached approximately 0.793 using all quantified 'Key Constituents' peaks published on page 1 of the SW0100 GC/MS certificate. The full page-2 identified-compounds table reports total identification of only 83% (BP5 column) / 81.79% (WAX column) of the chromatogram, and several remaining minor peaks (santalene, cedrene, and acoradiene isomers below 1%, plus an unidentified santalol analog at 0.81%) were left out of this record because they fall outside the page-1 Key Constituents summary and risked double-counting against the coeluting compounds already listed in the page-2 table.
