Oleyl diethanolamine

Oleyl diethanolamine (CAS 25307-17-9) is a fatty amine ethoxylate derived from oleic acid, combining a long unsaturated alkyl chain with two hydroxyethyl groups.

Where is Oleyl diethanolamine used?

• Metalworking and lubricants: emulsifier in cutting fluids, protecting ferrous surfaces while keeping oil-water systems stable
• Textile and leather: softening and wetting agent that improves fiber lubrication and dye penetration during finishing
• Water treatment: conditions metal surfaces and disperses contaminants in recirculating systems
• Personal care: emulsifier and rheology modifier in creams and conditioning products
• It serves as a corrosion inhibitor across multiple industrial sectors.

Commercial specifications

• Purity typically specified by amine value and hydroxyl number to confirm batch consistency
• Packaging in drums and intermediate bulk containers
