PIPERONYL ACETATE Chemical Properties,Usage,Production

Chemical Properties

light yellow liquid

Chemical Properties

Piperonyl acetate has a very sweet, light, floral–fruity odor with cherry-like undertones with a sweet, fruity flavor at low levels and bitter at high levels.

Occurrence

Reported found in endive (Cichorium endivia L.).

Uses

Piperonyl Acetate is a synthetic flavoring agent that is a stable, col- orless to light yellow liquid of heliotrope odor. it should be stored in glass or resin-lined containers. it is used in flavors for berry notes with applications in beverages, candy, ice cream, and baked goods at 50–90 ppm.

Preparation

By acetylation of the corresponding alcohol; by boiling dimethylpiperonyl amine with acetic anhydride.

Definition

ChEBI: Piperonyl acetate is a member of benzodioxoles.

Taste threshold values

Taste characteristics at 50 ppm: floral, soapy, fruity, berry and slightly jamy with a powdery nuance.

General Description

Clear pale yellow liquid. Insoluble in water.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

PIPERONYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: PIPERONYL ACETATE is an irritant.

Fire Hazard

PIPERONYL ACETATE is combustible.

Safety Profile

Moderately toxic by ingestion, A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
