In short

Bacdanol is IFF's campholenic sandalwood alcohol, a creamy, milky sandalwood note with rose facets. PubChem attaches the name to the (E)-isomer.

What Bacdanol smells like

Fraterworks describes Bacdanol as immediate sandalwood warmth enhanced by a creamy, almost cosmetic milkiness, with a sweet gourmand character suggesting vanilla and subtle rose facets, diffusive and long-lasting, and suggests it for cost-effective sandalwood accords and for supporting rose and jasmine hearts. IFF, its maker, describes Bacdanol as a powerful, true sandalwood note that gives long-lasting floral support and is extremely diffusive; Hekserij calls it a powerful sandalwood scent able to replace natural sandalwood extracts in part or entirely.

What makes Bacdanol distinctive

Sandalwood made creamy and almost cosmetic, with a sweet, vanilla-like gourmand side.

How Bacdanol is used

Used to build sandalwood accords and to give creamy woody depth to rose and jasmine hearts.

Typical role: backbone (used in large proportions as a structural material of an accord); blender (smooths the joins between other materials).

How Bacdanol differs from similar materials

Javanol
Javanol is one of the closest synthetic approaches to beta-santalol, clean and rosy; Bacdanol is creamier and sweeter, almost cosmetic, with a vanilla-like gourmand side.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.

Formulation considerations

IFF lists Bacdanol under CAS 28219-61-6, which does not specify the double-bond geometry and is on no PubChem compound record; PubChem gives the name Bacdanol to the (E)-isomer, 106185-75-5, which is the number published here.

Safety and compliance

Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (31 reports): H319 causes serious eye irritation (100% of reports); H411 toxic to aquatic life with long lasting effects (100% of reports). Unless it is harmonised, this is the notifiers' own classification, not a binding one.
