Linalool oxide pyranoid (CAS 14049-11-7) — Floral Heart Note Fragrance Ingredient
Linalool oxide pyranoid
CAS 14049-11-7
What Is Linalool oxide pyranoid?
Linalool oxide pyranoid is a synthetic fragrance compound used to add floral, woody nuances to perfumes and scented products. It’s found in air fresheners, fabric softeners, and some personal care items. This molecule enhances floral compositions with its unique ability to bridge fresh top notes with deeper woody base notes, making fragrances smell more natural and complex.
Safety Profile
GENERALLY SAFEWhat Does Linalool oxide pyranoid Smell Like?
Linalool oxide pyranoid unfolds with a delicate floralcy reminiscent of lily-of-the-valley dipped in rainwater, transitioning to a heart of damp oakmoss and tea leaves. The dry-down reveals subtle woody undertones with a whisper of honeyed sweetness. Unlike its parent linalool, this oxide carries an airy, almost ozonic quality that lifts compositions without overwhelming them. Its evolution suggests morning dew evaporating from a flower-strewn forest floor.
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used to create an illusion of ambergris’ mineralic facets, blending with citrus and woods to form the fragrance’s signature ‘liquid gold’ effect.
Provides subtle floral-oxidic lift to the carnation accord, enhancing the perfume’s ‘airborne’ quality without adding heaviness.
Chemistry, Properties & Perfumer Guide
The Chemistry
Linalool oxide pyranoid is a cyclic ether derivative of linalool, formed through acid-catalyzed cyclization. The pyranoid structure (six-membered oxygen-containing ring) differs from the furanoid form in ring size and stability. Synthetic production typically involves photo-oxidation of linalool followed by selective reduction. The molecule exists as cis/trans isomers, with the cis form generally exhibiting greater floral character. Its oxygen bridge increases polarity compared to linalool, reducing volatility while maintaining good diffusion.
