Description
Isobutyl acetate (CAS 110-19-0, EC 203-745-1) is an ester solvent and flavoring agent also known as isobutyl ethanoate, i-butyl acetate, and FEMA 2175. It carries no E-code designation. It belongs to the butyl acetate isomer family alongside n-, sec-, and tert-butyl acetate.
In food and beverage formulation, isobutyl acetate delivers a characteristic raspberry and pear note at concentrations typically below 50 ppm, functioning as a flavorant by volatilizing readily at room temperature to produce aroma impact. In coatings and personal care, it acts as a carrier solvent, dissolving resins and active ingredients while evaporating at a controlled rate to support film formation.
Isobutyl acetate is available in technical and FCC-grade forms, with the FCC grade meeting purity requirements for food contact applications under REACH registration. Standard packaging includes drums and IBC containers. Buyers should confirm REACH compliance documentation and SDS availability prior to procurement.
