In our reference data, Linalool is an EU-declared allergen.
Linalool is a naturally occurring terpene alcohol found in lavender, coriander, and many other plants, used in skincare primarily as a fragrance component. It readily oxidizes upon exposure to air, forming sensitizing hydroperoxides.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Common | A frequent fragrance allergen, especially from oxidized linalool; included in many baseline patch-test series. |
| Skin irritation | Uncommon | Redness, itching, or stinging, more likely with higher concentrations or oxidized product. |
| Photosensitivity / photoallergic reaction | Rare | Occasionally reported, though weaker than with some other fragrance terpenes. |
| Systemic or widespread reactions | Very rare | Generalized eczematous flares reported only in highly sensitized individuals. |
