What is Ethyldiethanolamine?
Ethyldiethanolamine (CAS 139-87-7) is a tertiary amine-alcohol for pH buffering, corrosion inhibition and emulsification.
Where is Ethyldiethanolamine used?
- Metalworking and industrial lubricants: corrosion inhibitor and pH stabilizer in cutting fluids and coolant concentrates, extending fluid service life
- Textile and leather processing: dispersing and leveling agent in dye baths
- Coatings and adhesives: pH control during emulsion polymerization and pigment dispersion stability
- Water treatment: metal chelation and scale inhibition in recirculating systems, sequestering hardness ions to prevent equipment fouling
- Its dual hydroxyl and amine functionality coordinates metal ions.
Commercial specifications
- Purity 98% to 99%
- COA and standard industrial safety compliance
- Clear to pale yellow liquid in drum and IBC quantities
