Product Description
Butyl acetate is a volatile, flammable ester compound with multiple isomers, among which n-butyl acetate and isobutyl acetate dominate commercial applications. With high volatility and a refreshing fruity scent, it delivers a pungent initial taste that fades into a sweet aftertaste. Its volatile vapor carries mild anesthetic properties, requiring standardized ventilation control during industrial operation.
As a naturally existing fragrance component, it is mainly applied in food flavor preparation. While its fragrance retention is relatively weak, its pure and vivid fruity tone makes it an indispensable blending ingredient in daily flavor formulation.
