Description
Diethyl malonate (CAS 105-53-3, EC 203-305-9) is a diethyl ester of malonic acid, commercially recognised under FEMA 2375 and trade references including Ethyl Malonate. It carries no E-code designation and is classified under HS code 29171910 for customs purposes.
In food and beverage formulation, diethyl malonate contributes apple and fruity top notes at low use levels, functioning as a flavorant through its ester character. In personal care and cosmetic applications, it serves as a solvent and carrier, improving the dispersion and skin delivery of active fragrance components within finished formulations.
Diethyl malonate is supplied as a liquid and is available in food-grade quality conforming to FCC specifications, with REACH compliance applicable for EU supply. Standard packaging formats include drums and intermediate bulk containers. Procurement teams should confirm grade suitability against FCC or relevant national food additive standards prior to use.
