Linalool Dårligst Fragrance Synthetic and Natural No known benefits Linalool at a glance A terpene alcohol found in certain plants, like lavender Functions as a perfuming agent Can cause skin sensitization Appears as a colorless liquid as a raw material Linalool description Linalool is a terpene alcohol and fragrant compound common in plant-derived oils such as those from lavender and coriander. In cosmetics and skin care its primary function is perfuming, due to its floral scent. Although linalool in itself is a weak skin sensitizer, the real issue comes when linalool’s exposed to air and oxidizes, creating allylic hydroperoxides. These hydroperoxides are potent skin sensitizers, which is why it’s best for skin’s health and appearance to avoid leave-on products that contain linalool. Like limonene, linalool is listed in the European Union as a known allergen and when used above 0.001% in leave-on products and 0.01% in rinse-off products it must be individually declared on the ingredient list, instead of just including it in the general designation of “fragrance”. Beyond cosmetics, linalool is also often used in the homecare industry (such as air fresheners). As a raw material, linalool is a colorless oil. Related ingredients: Limonene
