Ethyl butyrate

CAS: 105-54-4

Overview

Ethyl butyrate (CAS 105-54-4 ), also known by its FEMA 2427 designation, is a synthetic ester used primarily as a flavoring and fragrance ingredient across food, cosmetic, and industrial formulations.

It delivers a characteristic pineapple, banana, and tropical fruit profile that makes it one of the most recognized fruit flavor esters in commercial use today for various global markets.

In food and beverage manufacturing, it is incorporated into fruit-flavored confectionery, soft drinks, dairy products, and baked goods to replicate or enhance tropical and stone fruit notes.

Fragrance formulators use it in personal care products including lotions, shampoos, and body sprays where its fruity top note contributes to fresh, tropical scent profiles for consumers.

In lubricant and metalworking formulations, it functions as a synthetic ester base or additive where controlled lubricity and compatibility with other ester-based fluids are required for performance.

Cosmetic formulators also evaluate it as a skin-conditioning ester in emollient systems. It is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for buyers.

Food-grade material is produced to FCC specifications, supporting compliance for flavoring applications. Technical-grade material is available for industrial and fragrance end uses.
