Jasmolactone (Firmenich®)
No stock or price required. Add a batch later only if you want inventory tracking.
Short profile
Jasmine dominates the impression, with a full, naturalistic floral character and a creamy lactonic texture. Softer fruit notes suggest peach and apricot, accompanied by a coconut-milk nuance; tuberose also figures in the supplier's description. Its persistence supports a presence through the heart and into the base rather than a purely fleeting floral effect. The page describes lasting blotter performance but does not document a distinct opening-to-dry-down sequence or measured projection.
Effect in a formula
Adds convincing floral body and radiance to jasmine, tuberose and gardenia reconstructions. Its substantivity helps retain more volatile floral components within the composition. In osmanthus accords it connects the apricot aspect with the floral structure, while coconut accords and solar fragrances can use its creamy floral contribution.
Use and dosage
The supplier suggests 0.1–1% of the neat material in fragrance concentrate to give white-floral accords a noticeable radiant contribution. A separate laboratory note gives 0.05–0.5% in finished fragrance; this is a different concentration basis, not an alternative concentrate range. These are formulation recommendations, not IFRA limits.
No confirmed manufacturer use level for this exact product.
Behaviour and performance
- Tenacity
- The descriptive text reports more than 48 hours on a smelling strip. Elsewhere, the page lists 400 hours on blotter in data attributed to TGSC. Neither figure is accompanied by a test dilution or detailed protocol, so the two reports should be kept distinct.
Diffusion, tenacity and note impact are not combined into a single performance score.
Dissolving and diluting
- Solvents
- Ethanol, DPG and IPM are reported to produce clear solutions readily. Water solubility is described as negligible.
- Working dilution
- For ethanol-based evaluation, the laboratory guidance specifies 0.1% for smelling and 1% as a working stock. The general use section instead recommends a 10% working solution, and the page identifies a separately sold 10% ethanol version. These are distinct supplier recommendations rather than a single prescribed dilution.
- Appearance
- Liquid, ranging from colourless to a faint yellow tint.
