Linalool oxide (CAS 1365-19-1) — Floral Top to middle Note Fragrance Ingredient
Linalool oxide
CAS 1365-19-1
What Is Linalool oxide?
Linalool oxide is a fragrance compound derived from linalool, commonly found in lavender and bergamot oils. You’ll encounter it in floral perfumes, soaps, and household cleaners for its fresh, slightly woody scent. It matters because it adds complexity to fragrances, acting as a bridge between bright top notes and deeper base notes, creating a more rounded olfactory experience.
Safety Profile
GENERALLY SAFEWhat Does Linalool oxide Smell Like?
Linalool oxide presents a delicate balance between floral freshness and woody depth. Imagine the first dewy moments after rainfall in a lavender field, where crisp floralcy meets damp earth. The initial burst carries a subtle citrus-tinged floral character, like bergamot peeking through linen curtains. As it evolves, it reveals a soft, almost tea-like quality with whispers of oxidized wood – think of well-worn cedar chests lined with dried lavender sachets. In drydown, it leaves a transparent woody-musky trace that lingers like the memory of a garden stroll.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used here to bridge the citrus top notes to herbal heart, creating the perfume’s signature ‘watercolor’ effect where notes bleed beautifully into each other.
Provides subtle oxidation effects that enhance the carnation-carnation accord, like petals slightly bruised from handling.
Chemistry, Properties & Perfumer Guide
The Chemistry
Linalool oxide is a furanoid terpene ether formed through oxidation of linalool. The molecule exists in several stereoisomeric forms, with the cis and trans configurations each imparting slightly different olfactory characteristics. Industrial production typically involves acid-catalyzed cyclization of linalool, though enzymatic oxidation routes are being developed for more sustainable production.
