У парфумерії
Aldambre is used to abstract woody bases and to create contemporary mineral effects. Added at 0.5-2%, it strips earthiness from vetiver and patchouli. It can be combined with salicylates for hot stone accords or with Ambroxan to amplify mineral facets. It creates mineral accords and adds metallic lift to woods. At higher doses, it becomes a statement material for conceptual fragrances. It is described as a heart-note musk that bridges top and base. It can be used to modernise aldehydic florals.
