Intensely animalic and musty absolute with a distinctive goaty, unwashed-hair character over a warm woody-earthy base. Develops a soft, dusty sweetness on drydown with subtle powdery-orris facets. Highly polarising — used in trace amounts as a naturalistic animalic fixative.AI · claude-opus-4-7

Costus Absolute is a semi-solid mass or very viscous liquid of pale amber or brownish-amber color.
The odor of the absolute is soft, sweet-woody and fatty without any unpleasant harsh or rancid-fatty notes.
Costus Absolute and Costus Concréte (costus resinoid) are used in similar perfumery combinations as those described under Costus Oil.
Extraction with hydrocarbon solvents at modest temperature will produce a concrete of a rich and true-to-nature odor. An absolute is produced from the concrete by the conventional alcohol extraction method.
