Description
N-Undecanoic acid (CAS 112-37-8), also known as undecoic acid, UDA, or by the flavour industry reference FEMA 3245, is a saturated medium-chain fatty acid with eleven carbon atoms. It carries no assigned E-code and is catalogued under EC 203-964-2 for regulatory identification within the European chemical inventory.
In personal care formulations, it functions as an emulsifier and emollient by reducing interfacial tension between oil and water phases, supporting stable cream and lotion systems. In metalworking and lubricant applications, it acts as a boundary lubricant through adsorption onto metal surfaces, reducing friction and wear under load.
N-Undecanoic acid is available in technical and cosmetic grades as a low melting solid, supplied in fibre drums or lined cartons. It falls under REACH registration requirements and is classified under HS code 29159080. Buyers should confirm grade suitability against FCC or Ph.Eur. specifications depending on the intended application.
