A rich, warm coumarin-forward absolute smelling of new-mown hay, sweet tobacco, and toasted almond with a creamy vanillic undertone. Develops a soft, boozy-balsamic depth over time with subtle hints of dried fruit and caramel. Signature is the deep, powdery-sweet coumarin heart that lingers.AI · claude-opus-4-7

Tonka Absolute is a semi-solid or crystalline mass of pale amber or pale brownish-yellow color.
Its odor is very rich, sweet and warm, distinctly coumarinic-herbaceous, with a prune-like or caramellic-sweet undertone.
Tonka Absolute is used as a fixative and non-floral sweetener which introduces warm notes in chypres, fougères, new mown hay bases, lavender bouquets, Oriental bases, etc.
Tonka Absolute can not be used in flavors in those countries where a coumarin ban exists (U.S.A. and others).
A tincture can be prepared from dried comminuted tonka beans with ethyl alcohol. Tonka extracts may also be prepared by direct hydro-alcoholic percolation of the crushed seeds, usually without the application of heat.
