Short profile
Herbal, medicinal, woody, fresh, camphoraceous, damp, musty, earthy and lightly spicy odor profile.
Effect in a formula
At trace levels, the oil introduces an unpolished herbal character with medicinal bite and damp woody shading. Its main applications are herbal, fougère and spa compositions, where it can make the aromatic profile feel less conventionally perfumed. In functional fragrances it reinforces a cleaning-product association, but the medicinal character can readily become dominant.
Use and dosage
The supplier gives 0.05–0.5% of the fragrance concentrate as a typical fine-fragrance range, with small additions intended to accent herbal and fougère structures. Higher dosing is mentioned for personal-care and cleaning applications without a concentrate-level range. A separate laboratory section gives 0.1–2% in finished fragrance; this is a different dosing basis and should not be substituted for the concentrate guidance. These are formulation recommendations, not IFRA limits.
No confirmed manufacturer use level for this exact product.
Behaviour and performance

Diffusion, tenacity and note impact are not combined into a single performance score.
Dissolving and diluting
