Description
Ethyl palmitate (CAS 628-97-7, EC 211-064-6) is a fatty acid ethyl ester derived from palmitic acid, also identified by the trade designations FEMA 2451 and NSC 8918, and commercially referenced as ethyl cetylate or ethyl hexadecanoate. It carries no assigned E-code and is classified under HS code 29157020.
In personal care formulations, ethyl palmitate functions as an emollient and emulsion stabilizer by forming a lipid film that reduces transepidermal water loss while improving spreadability in creams and lotions. In metalworking and lubricant applications, its ester structure provides boundary lubrication, reducing friction between metal surfaces under moderate load conditions.
Ethyl palmitate is supplied in cosmetic and technical grades and is subject to REACH registration requirements within the EU. Procurement quantities are typically available in drum and IBC formats. Buyers should confirm grade suitability against FCC specifications for food-contact applications.
