Ethyl Vanillin

Ethyl Vanillin is a synthetic flavor and fragrance ingredient that supplies a stronger vanilla-like scent than vanillin itself, used in fragranced skincare, lip products, candles, and other personal care items. Animal skin-sensitization testing (a mouse local lymph node assay) found no sensitizing potential up to 50% concentration, but as with any added fragrance material, people who already react to fragrance ingredients in general may still want to patch test first. It is a distinct molecule from vanillin, which the EU added to its expanded fragrance-allergen labeling list in 2023; ethyl vanillin itself is not on that list.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
