In short
Cyclamen aldehyde is a synthetic aldehyde with a fresh, green-floral note named after the cyclamen flower. It adds a watery, airy floral freshness.
What Cyclamen Aldehyde smells like
Cyclamen aldehyde is a powerful green floral aldehyde with a watery, vegetal side. Arctander, as quoted by PerfumersWorld, mentions pronounced vegetable cucumber-melon notes; suppliers describe a strong floral-green odour with cucumber and melon, and the skin and watery flesh of unripe cucumber and melon. Other sources add rhubarb, lily of the valley and a linden-blossom floral impression.

What makes Cyclamen Aldehyde distinctive
Its vegetable side. Among the muguet-type aldehydes it is the one with the clearest cucumber-and-melon rind character, closer to a green watery floral than to a pure lily.
How Cyclamen Aldehyde is used
Used for watery, green floral effects — cyclamen, muguet and linden — mostly in the heart, though its diffusion lets it show in the top.
Typical role: modifier (used in small amounts to change the character of a blend); lift (adds diffusion and radiance, especially at the top).
How Cyclamen Aldehyde differs from similar materials
- Florhydral
- Florhydral is a fresher, more floral green muguet with hyacinth; cyclamen aldehyde is more vegetal, with cucumber and melon.
- Silvial
- Silvial is a cleaner, more floral watery muguet; cyclamen aldehyde has a stronger cucumber-melon vegetal side.
- Helional
- Helional is ozonic and hay-like with cyclamen; cyclamen aldehyde is greener and more vegetal, with cucumber and melon.
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.

Safety and compliance
The IFRA Standards Library lists a Standard covering Cyclamen Aldehyde:
- "Cyclamen aldehyde" — type not stated in the library listing, 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. Companies notifying the ECHA C&L Inventory classify it (2,062 reports): H315 causes skin irritation (98.8% of reports); H317 may cause an allergic skin reaction (95.9% of reports); H412 harmful to aquatic life with long lasting effects (76.6% of reports); H411 toxic to aquatic life with long lasting effects (15.1% of reports); H361 suspected of damaging fertility or the unborn child (12.3% of reports). 1 of the reports find it does not meet the hazard criteria. 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.
