Description
Ethyl butyrate (CAS 105-54-4), also known as butyric ether, ethyl butanoate, or ethyl n-butyrate, is a short-chain ester produced by the reaction of butyric acid with ethanol. It carries no E-number designation and is classified under HS code 29156000.
In food and beverage manufacturing, ethyl butyrate delivers characteristic pineapple and tropical fruit notes at concentrations typically below 50 ppm, making it a cost-effective flavoring agent in confectionery, beverages, and dairy products. In personal care formulations, it functions as an emollient by integrating into the lipid matrix of skin, reducing transepidermal water loss.
Ethyl butyrate is supplied as a liquid in compliance with FCC (Food Chemicals Codex) and REACH regulations, with food-grade and cosmetic-grade variants available depending on application requirements. Standard packaging includes drums and IBCs, with documentation supporting EU food and cosmetic regulatory submissions.
