In short
Vertoliff is an IFF cyclohexene carbaldehyde with a green, aldehydic odour. IFF says it adds freshness and sparkle to a fragrance.
What Vertoliff smells like
IFF describes Vertoliff as adding freshness and sparkle to fragrances, with a typical use up to 2%. The Good Scents Company gives its odour type as green. Fraterworks describes a green aldehydic note with herbal-citrus facets, especially lime and unripe peel, and a bark-like quality, strong enough to need diluting.

What makes Vertoliff distinctive
A green aldehyde that leans towards unripe lime peel.
How Vertoliff is used
IFF gives a typical use of up to 2%, for freshness and sparkle in the top note.
Typical role: modifier (used in small amounts to change the character of a blend); lift (adds diffusion and radiance, especially at the top).
How Vertoliff differs from similar materials
- Triplal
- Triplal is the classic sharp green aldehyde; Vertoliff, a close structural relative, is described with more lime and unripe peel.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
IFF lists CAS 27939-60-2 / 67801-65-4; strong, so dose from dilution.

Safety and compliance
The IFRA Standards Library lists a Standard covering Vertoliff:
- "Dimethylcyclohex-3-ene-1-carbaldehyde (mixed isomers)" — Restriction, 49th Amendment, published 2020-01
Limits differ by product category and are set out in the Standard itself; this page does not reproduce them. The list above reflects the library as read on 19 October 2026.
Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. It has a harmonised EU classification (Regulation (EC) No 1272/2008, Annex VI): H317 may cause an allergic skin reaction. Companies notifying the ECHA C&L Inventory classify it (1,580 reports): H315 causes skin irritation (100% of reports); H302 harmful if swallowed (99.3% of reports); H411 toxic to aquatic life with long lasting effects (87.2% of reports); H317 may cause an allergic skin reaction (85.6% of reports); H319 causes serious eye irritation (14.3% of reports); H412 harmful to aquatic life with long lasting effects (12.8% of reports). A skin sensitiser classification concerns handling the neat material and the dose in a finished product; the IFRA Standards, where they apply, set the limits. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
