Short profile
Honeyed sweetness and dry hay form the core of this oil's odour, contrasted by a pronounced curry-like, fenugreek spice character. Dried-fruit and tobacco nuances broaden the profile, while a mildly bitter medicinal edge prevents it from reading as purely sweet. Herbal and fruity accents add complexity to this forceful, readily dominant natural material. The supplier describes lasting presence but provides no staged blotter observations or specific projection data, so an opening-to-dry-down progression cannot be established.
Use and dosage
The supplier's concentrate guidance is 0.1–1%, generally sufficient for this powerful material. Start at the lower end and assess within the complete accord, since increasing the dose can shift the balance towards curry spice. A separate range of 0.1–2% is given for finished fragrance, not concentrate. These are formulation recommendations, not IFRA limits.
No confirmed manufacturer use level for this exact product.
