Organoleptic Properties

Odor Type: Woody
woody, dry, cedar, ambergris, earthy, vetiver
Odor strength medium
Substantivity 124 hour(s) at 100.00 %
Luebke, William tgsc, (1985) At 100.00 %. woody dry cedar ambergris earthy vetiver
General comment A dry, very diffusive, true ambergris note that also has rich woody cedarwood, dry aspects
Works exceptionally well alongside MCK (Vertofix, methyl cedryl ketone) and in synergy with stronger amber ingredients like Ambrofix or Fixateur 505. According to Arcadi Boix Camps it is “extraordinary and has a bright quality between amber and patchouli. This is one of my favourite aromatics and it can be used in luxury perfumery as well as to give vitality to the qualities of Vertofix, as in functional perfumery, where it confers an uncommon character and fixes marvellously well the floral-aldehydic notes of undecylenic and cyclamen aldehydes, Lilial, Lyral and others.” Woody, cedarwood, amber
