Dihydroeugenol (Firmenich®)

Clove dominates the profile, with a rounded spicy character rather than Eugenol's more piercing pungency. Vanilla-like warmth and restrained sweetness accompany a woody, balsamic body; compared with Isoeugenol, the character is less floral. The lingering impression becomes dry and phenolic, with smoky and faintly medicinal nuances. The supplier rates both odour strength and presence in a mixture at 5/10, but provides no timed opening-to-heart blotter observations or separate projection assessment.

Provides a rounded clove accent with vanilla warmth, allowing spice to be introduced without Eugenol's sharper edge. It adds depth to rose and amber compositions and supports woody-spicy bases. The supplier also identifies it as a depth-building component for spice and smoke accords.

The supplier gives 0.2–0.7% of the fragrance formula as its customary formulation range. A separate laboratory section cites 0.1–2% in the finished fragrance, which is a different dosing basis and should not be treated as a concentrate range. These are usage suggestions, not IFRA limits; the page does not assign distinct concentrate doses for trace effects or deliberate overdosing.

No confirmed manufacturer use level for this exact product.

Tenacity

The page reports 72 hours of blotter substantivity, attributing this figure to TGSC. Evaluation dilution and other test conditions are not specified.

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

Solvents

Readily forms clear solutions in ethanol, DPG and IPM. Water solubility is limited, while solubility in fats is reported.

Working dilution

Use a 10% working solution for compounding and a 1% dilution for olfactory evaluation. Ethanol is the page's primary dilution solvent; DPG and IPM are also listed as suitable solvents.

Appearance

A liquid ranging from colourless to a faint yellow tint.
