Safety Profile
GENERALLY SAFEWhat Does 9-Decenyl acetate Smell Like?
9-Decenyl acetate opens with a burst of crisp, green pear skin and a hint of unripe banana. As it evolves, it reveals a delicate floral undertone reminiscent of lily-of-the-valley, with a clean, slightly waxy character. The dry-down is subtle, leaving a faint aquatic freshness that lingers close to the skin. Its overall effect is like biting into a just-ripe Bartlett pear with a background of dew-covered spring flowers.
Chemistry, Properties & Perfumer Guide
The Chemistry
9-Decenyl acetate is a synthetic ester formed by the acetylation of 9-decen-1-ol. As a straight-chain unsaturated ester, it belongs to the class of aliphatic acetates that are prized in perfumery for their fresh, fruity characteristics. While not found in nature, its structure mimics certain fruity esters occurring in pears and other fruits. Industrial synthesis typically involves direct esterification of the corresponding alcohol with acetic anhydride under controlled conditions.
