In short

Timberol (also sold as Norlimbanol) is a synthetic woody-amber material with a dry, powerful, animalic woody note.

What Timberol smells like

Timberol (Symrise) is highly diffusive and powdery-woody with notes of ambergris, in Symrise's data sheet; The Good Scents Company lists dry, sawdust, woody, powdery, amber and sandalwood from a 1987 evaluation of a Dragoco sample; Scentspiracy dry, sharp, woody-ambery with cedarwood facets, clean, substantive and very strong. Timberol is the high-cis form; its trans-rich counterpart, Norlimbanol (Firmenich), is reported stronger and more amber-like.

What makes Timberol distinctive

Sawdust and ambergris: an intensely dry, powdery wood with great diffusion.

Where the descriptions disagree: The record lists Norlimbanol as another name; one source describes Norlimbanol as the distinct trans-rich form, stronger and more amber-like.

How Timberol is used

Used for dry woody-amber diffusion in woody, masculine and functional compositions.

Typical role: modifier (used in small amounts to change the character of a blend); fixative (slow to evaporate; helps a blend last and holds lighter notes).

How Timberol differs from similar materials

Karanal
Karanal is a radiant woody amber with a faint watermelon-like fruitiness; Timberol is drier and more powdery, sawdust-like.
Ambrocenide
Ambrocenide is a sharper, mineral ambergris with smoky facets; Timberol is the drier, powdery sawdust wood.
Mahagonate
Mahagonate is dry sawdust with herbal patchouli and laurel; Timberol adds ambergris and powder.

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

Very strong; covered by an IFRA Standard.

Safety and compliance

The IFRA Standards Library lists a Standard covering Timberol:

  • "1-(2,2,6-Trimethylcyclohexyl)-3-hexanol" — Restriction, 51st Amendment, published 2023-06

Limits differ by product category and are set out in the Standard itself; this page does not reproduce them. The list above reflects the library as read on 19 October 2026.

Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (1,690 reports): H317 may cause an allergic skin reaction (79.8% of reports); H315 causes skin irritation (20.1% of reports). 1 of the reports find it does not meet the hazard criteria. A skin sensitiser classification concerns handling the neat material and the dose in a finished product; the IFRA Standards, where they apply, set the limits. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
