Description
Ethyl propionate (CAS 105-37-3, EC 203-291-4, C5H10O2) is a short-chain ester also identified by trade references FEMA 2456 and NSC 8848, and by the structural abbreviation C2H5COOC2H5. It carries no E-code designation and is commercially recognised under the synonyms propionic ester and propionic ether.
In food and beverage formulation, ethyl propionate delivers characteristic fruity, rum-like top notes at concentrations typically below 50 ppm, functioning as a flavour-modifying ester. In personal care products, it acts as an emollient by forming a thin occlusive film on skin, reducing transepidermal water loss without heavy residue.
Ethyl propionate is supplied in food-grade quality meeting FCC specifications and is subject to REACH registration within the EU. It is available in standard drum and IBC packaging suitable for industrial procurement. Buyers should confirm compliance documentation, including SDS and certificate of analysis, prior to formulation use.
