Caryophyllene acetylated
CAS 75975-83-6
What Is Caryophyllene acetylated?
Acetylated caryophyllene is a synthetic fragrance ingredient derived from caryophyllene, a natural component found in cloves and cannabis. It’s used in perfumery to enhance woody and spicy notes. This modified molecule offers perfumers greater stability and intensity compared to its natural counterpart, making it valuable for creating long-lasting fragrance bases.
Safety Profile
USE WITH AWARENESSWhat Does Caryophyllene acetylated Smell Like?
Acetylated caryophyllene presents a rich, woody-spicy character with pronounced clove-like facets. The acetylation process intensifies the natural warmth of β-caryophyllene, yielding a scent that evolves from sharp peppery top notes to a deep, resinous heart. In drydown, it reveals surprising sweetness reminiscent of aged tobacco leaves, with lingering balsamic undertones that provide excellent fixation.
Chemistry, Properties & Perfumer Guide
The Chemistry
Acetylated caryophyllene is a semisynthetic derivative where the hydroxyl group of caryophyllene alcohol undergoes esterification with acetic acid. This modification enhances the molecule’s volatility profile while maintaining its characteristic sesquiterpene skeleton. The acetylation process typically employs acid catalysis, with careful control to prevent rearrangement of the delicate caryophyllene framework.
