Vetiveryl Acetate Supra (Synarome®)
No stock or price required. Add a batch later only if you want inventory tracking.
Short profile
Dry woody vetiver character with a cleaner, brighter impression than vetiver oil.
Effect in a formula
Provides a persistent vetiver-wood foundation with less earthy weight than the original oil, supporting fixation while keeping the composition relatively light. Its dry, clean character suits chypre structures and masculine fragrances, with further applications in fougère and fresh woody compositions.
Use and dosage
The supplier gives 0.3–0.9% for the fragrance formula, but elsewhere cites 1–10% in finished fragrance for vetiver, chypre and fougère bases. These inconsistent statements do not establish an unambiguous concentrate-use range. They are reported formulation guidance, not an IFRA limit.
No confirmed manufacturer use level for this exact product.
Behaviour and performance
- Tenacity
- Described as a persistent base material lasting many hours to days, without a defined test protocol. The supplier recommends evaluating a 10% solution on a scent strip over several hours, when the woody character becomes apparent; no measured blotter endpoint is supplied.
Diffusion, tenacity and note impact are not combined into a single performance score.
Dissolving and diluting
- Solvents
- Reported to form clear solutions with ethanol, IPM and DPG.
- Working dilution
- For handling and compounding, the supplier lists neat material or a 10% dilution. A 10% solution is recommended for smelling, with ethanol identified in the linked dilution setup; DPG and IPM are also listed as suitable solvents.
- Appearance
- Viscous liquid with colour ranging from pale yellow to amber.
