What Boisambrene Forte smells like

Boisambrene Forte ((ethoxymethoxy)cyclododecane, also sold as Amberwood F) has a noble woody note with a tendency towards ambergris, in Kao's description, used for a woody-amber note with a warm, sweet and flowery effect and as a modifier alongside other woods.

What makes Boisambrene Forte distinctive

An elegant woody amber with a warm, slightly flowery sweetness — softer than the dry ambers.

How Boisambrene Forte is used

Used as a woody-amber modifier in woody, oriental, masculine and functional compositions.

Typical role: fixative (slow to evaporate; helps a blend last and holds lighter notes); blender (smooths the joins between other materials).

How Boisambrene Forte differs from similar materials

Cedramber

Cedramber is drier, a true-ambergris cedar note; Boisambrene Forte is warmer and sweeter, with a flowery effect.

Amber Core

Amber Core is softer and more delicate; Boisambrene Forte is a more diffusive, noble woody amber.

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.

Safety and compliance

The IFRA Standards Library lists a Standard covering Boisambrene Forte:

• "(Ethoxymethoxy)-cyclododecane" — 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 (1,746 reports): H317 may cause an allergic skin reaction (86.5% of reports); H411 toxic to aquatic life with long lasting effects (86.5% of reports); H412 harmful to aquatic life with long lasting effects (13.4% of reports); H319 causes serious eye irritation (11.2% 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.
