Linalool is a classic perfumery material celebrated for its clean floral–citrus tone-airy, soft, and immediately pleasant. At low levels it suggests lavender and orange blossom; at higher dosage it turns subtly herbal-woody, lending smoothness and finesse to a blend.

Found naturally in lavender, coriander, ho leaf, and rosewood, Linalool is also widely available as a high-purity isolate. Versatile by design, it can stand as a distinct note or act as a “rounding” modifier across floral, citrus, fougère, woody, and soapy accords.

Olfactively, Linalool shows medium volatility with good diffusion, smoothing the transition from top to heart and creating a seamless opening. It tames harsh edges (over-sharp citrus, overly camphoraceous herbs) and enhances a clean, polished impression.

Physically, Linalool is a colorless to pale-yellow liquid that is soluble in ethanol and oils and insoluble in water. Used correctly, it can subtly improve tenacity on skin and help a scent project evenly in home fragrance formats (candles, room sprays, reed diffusers).

Applications span fine fragrance (EDP/EDT), body mists, shampoos, shower gels, lotions, and home & fabric care. Because it occurs naturally in many essential oils, Linalool is also employed to standardize floral profiles, supporting batch-to-batch consistency across harvests.

Safety note: Linalool is a labelable fragrance allergen in many markets. Compliance with IFRA category limits is recommended. Protect from oxidation during storage-keep tightly closed, away from light and heat; antioxidants may be added when appropriate.

At SCENT, we select Linalool for high purity, clean odor, and low by-products, making it suitable for both cosmetic formulations and artistic perfumery-a dependable building block for modern, elegant, everyday wear.

Specification
Oxidation products of Linalool, especially hydroperoxides, have been demonstrated to be potent sensitizers.
d-, l- and dl-Linalool and natural products containing substantial amounts of it, should only be used when the level of (hydro)peroxides is kept to the lowest practical level, for instance by adding antioxidants at the time of production. The addition of 0.1% BHT or α-Tocopherol for example has shown great efficiency. Such products should have a peroxide value of less than 20 millimoles per liter, determined according to the IFRA analytical method for the determination of the peroxide value, which can be downloaded from the IFRA website (www.ifrafragrance.org).
