Oud Synthetic 10760 E (Firmenich®)

Oud, dry woody, resinous, balsamic sweet, smoky, leathery, phenolic and mildly animalic odor profile.

Provides a substantial woody-resinous foundation with a dark tonal emphasis and a fixative role. It can anchor oud-led compositions or introduce an ambery oud inflection at smaller proportions. Rose accords benefit from its oud contrast, while leather and spice structures gain a cohesive resinous warmth; woody and amber compositions are also identified as suitable applications.

The supplier suggests 1–15% of the fragrance concentrate. A few percent can introduce an oud-amber character into otherwise Western-style structures, whereas oud-focused formulas may use it as a principal foundation. A separate recommendation of 0.5–5% refers to the finished fragrance, not the concentrate. These are formulation recommendations, not IFRA limits.

No confirmed manufacturer use level for this exact product.

Tenacity

The supplier reports persistence over several days. No blotter-specific duration, evaluation dilution or test conditions are supplied.

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

Solvents

Clear dissolution is reported in TEC, benzyl benzoate and IPM. Ethanol at 96% strength can produce haze, and water-containing alcohol is also flagged for possible cloudiness. For alcoholic formulations, blend the base into the concentrate before introducing the alcohol.

Working dilution

Use the supplier's 10% working strength for compounding and 1% strength for initial odour assessment. Listed solvents include TEC, benzyl benzoate, IPM and ethanol; the first three are reported to give clear solutions, while ethanol requires attention to haze. No single solvent is explicitly assigned to the 1% evaluation recommendation.

Appearance

Yellowish base with a viscous consistency.
