No stock or price required. Add a batch later only if you want inventory tracking.
Short profile
The opening combines citrus brightness with pointed green notes and a clear lemongrass association. A faint oily undertone adds texture, while stronger concentrations reveal a mushroom nuance. The supplier also describes unripe banana and an airy, solvent-like edge. Its character is predominantly early and volatile; the page does not describe a separate heart or dry-down profile or measured projection.
Effect in a formula
Provides an incisive green-citrus accent at the opening, adding a rawer dimension of freshness alongside citrus peel oils. Its main application is in citrus, herbal and fresh compositions, with additional relevance to lemongrass and green accords.
Use and dosage
The supplier gives 0.1–2% in the fragrance concentrate for an early citrus-green accent. This is formulation guidance, not an IFRA limit. Elsewhere the page assigns the same range to finished fragrance, so its stated dosage basis is not consistent.
No confirmed manufacturer use level for this exact product.
Behaviour and performance
- Tenacity
- The page reports 4 hours of blotter substantivity, attributed to TGSC, without specifying test dilution. Its lab commentary separately describes the top-note contribution as disappearing after about 20 minutes; that observation is not identified as a blotter test.
Diffusion, tenacity and note impact are not combined into a single performance score.
Good areas of use
Dissolving and diluting
- Solvents
- Water does not dissolve the material. Alcohol and ether are reported to be fully miscible with it; ethanol, DPG and IPM are specifically described as giving clear solutions promptly.
- Working dilution
- Prepare a 10% working solution in ethanol for formulation work, and use 1% for olfactory evaluation. DPG and IPM are also listed as suitable dilution vehicles.
- Appearance
- Liquid, with no visible colour reported.
