Description
Isoamyl butyrate (CAS 106-27-4) is a synthetic ester produced by the esterification of isoamyl alcohol with butyric acid. It is commercially identified under FEMA 2060 and also referenced as isoamyl butanoate or amyl butyrate. No E-code designation applies to this ingredient.
In food and beverage formulation, isoamyl butyrate delivers a characteristic banana and pear flavour profile at concentrations typically between 1 and 50 ppm, making it a functional flavorant in confectionery, beverages, and dairy applications. In personal care, it functions as an emollient ester, improving skin feel and spreadability in leave-on formulations by reducing surface friction between the skin and the product matrix.
Isoamyl butyrate is supplied as a neat liquid meeting FCC (Food Chemicals Codex) grade specifications and is subject to REACH registration within the EU. It is classified under HS code 29156019 for customs purposes. Packaging is available in standard drum formats suited to industrial procurement volumes.
