Oleic acid diethanolamide

Oleic acid diethanolamide (CAS 93-83-4, EC 700-972-2) is a fatty acid alkanolamide derived from oleic acid and diethanolamine, with the molecular formula C22H43NO3. It is commercially available under trade names including Pamsurf, Alrosolo, Amidex O, and Emid 6545. No E-code designation applies to this substance.

In metalworking fluids, it functions as an emulsifier and corrosion inhibitor by stabilising oil-in-water systems through its amphiphilic structure. In textile processing, it acts as a scouring agent, reducing interfacial tension to lift oils and soils from fibre surfaces. It also serves as a foam booster and viscosity modifier in personal care cleansing formulations.

This material is supplied under REACH registration and is available in industrial drum and IBC formats. Buyers should confirm grade specification, free amine content, and applicable regional compliance requirements prior to procurement.
