In short
Ultravanil is Givaudan's trade name for 2-ethoxy-4-methylphenol, a vanilla booster with a phenolic depth. It discolours far less than vanillin or ethyl vanillin.
What Ultravanil smells like
Fraterworks describes Ultravanil as vanilla with a discreet caramel edge and a clear phenolic depth with woody and spicy undertones, used mainly as a vanilla booster and far less discolouring than vanillin or ethyl vanillin. ChemicalBook gives the odour type as vanilla, with woody, spicy and guaiacol notes. A patent application notes that, as an o-alkoxy phenol, it has a phenolic malodour beside its vanillin-like odour.

What makes Ultravanil distinctive
A vanilla booster with a phenolic depth, closer to the guaiacol side of vanilla than to its sweetness.
How Ultravanil is used
Used with vanillin and ethyl vanillin as a booster that discolours far less.
Typical role: modifier (used in small amounts to change the character of a blend).
How Ultravanil differs from similar materials
- Ethyl Vanillin
- Ethyl vanillin is a sweeter, stronger vanilla; Ultravanil adds a phenolic, smoky depth and is used beside it as a booster that discolours less.
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
Also sold as an 80% solution in dipropylene glycol (Ultravanil 80).

Safety and compliance
The IFRA Standards Library lists a Standard covering Ultravanil:
- "2-Ethoxy-4-methylphenol" — 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. Companies notifying the ECHA C&L Inventory classify it (209 reports): H315 causes skin irritation (99.5% of reports); H302 harmful if swallowed (97.6% of reports); H317 may cause an allergic skin reaction (97.6% of reports); H318 causes serious eye damage (97.6% 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.
