In short
Firsantol is a dsm-firmenich sandalwood alcohol made from upcycled turpentine. Firmenich calls it a very powerful and natural sandalwood note.
What Firsantol smells like
Firmenich describes Firsantol as a very powerful and natural sandalwood note for any type of fragrance, with improved tenacity (two weeks on a strip), for heart and base at about 0.3-2% in fine fragrance, made from upcycled turpentine with more than 50% renewable carbon. A 2012 Chimia report calls it substantive, fresh and very close to natural sandalwood. Fraterworks finds it slightly weaker than Javanol and Polysantol but the most diffusive.

What makes Firsantol distinctive
A sandalwood alcohol prized for how close it is to the natural oil.
How Firsantol is used
Firmenich suggests about 0.3-2% in fine fragrance as a heart and base note, less in functional products.
Typical role: backbone (used in large proportions as a structural material of an accord).
How Firsantol differs from similar materials
- Brahmanol
- Both are campholenic sandalwood alcohols; Firsantol is described as very powerful, fresh and natural, Brahmanol as mild and giving body.
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.
