Safety Profile
GENERALLY SAFEWhat Does Amyl hexanoate Smell Like?
Amyl hexanoate bursts with a bright, banana-like sweetness reminiscent of tropical fruit cocktails. The initial impression is juicy and slightly green, like peeling a just-ripe banana. As it evolves, it reveals subtle pear and pineapple nuances with a creamy undertone. The dry-down retains a soft fruity character but becomes more diffuse, blending seamlessly with floral and woody notes. Its volatility makes it perfect for creating naturalistic top notes that don’t overpower.
Chemistry, Properties & Perfumer Guide
The Chemistry
Amyl hexanoate is an ester formed by the condensation of hexanoic acid and amyl alcohol. Industrially produced via acid-catalyzed esterification, it’s a staple in flavor and fragrance chemistry. The molecule lacks chiral centers, making synthesis straightforward. Its relatively small size contributes to high volatility and intense fruity odor.
