What is Isoamyl acetate?
Isoamyl acetate (CAS 123-92-2), also known as isopentyl acetate, is an ester-based solvent and flavoring agent with a banana-pear aroma. FEMA 2055.
Where is Isoamyl acetate used?
- Industrial coatings and printing: fast-evaporating solvent in nitrocellulose-based inks and lacquers
- Food manufacturing: banana and pear notes in confectionery, beverages and baked goods
- Fragrance and personal care: scent character and solvent function in fragrance blends and nail care products
- Aerosol formulations and specialty coatings: carrier solvent for controlled viscosity and clean evaporation
- It supports print quality and adhesion on flexible substrates.
Good to know: Food-grade material meets FCC specifications; technical-grade is for industrial solvent use. Purity typically 98% to 99%+ depending on end use.
Commercial specifications
- Purity typically 98% to 99%+ depending on end use
- Technical-grade for industrial solvent applications
- Clear liquid in drum and IBC quantities
