What is Butylethanolamine?
Butylethanolamine (CAS 111-75-1), also known as 2-butylaminoethanol, is a bifunctional amine-alcohol for industrial formulations needing pH control and surface-active behaviour.
Where is Butylethanolamine used?
- Metalworking fluids: neutralises acidic byproducts
- Coatings: neutralising amine for waterborne resin systems, improving dispersion stability and film formation
- Textile and leather processing: emulsification aid in lubricating and softening baths
- Adhesives and sealants: pH adjustment during formulation for compatibility between reactive components
- It provides corrosion protection on ferrous and non-ferrous metal surfaces, extending fluid service life.
Commercial specifications
- Purity typically 98% and above
- Certificates of analysis against agreed specifications
- Clear liquid in drums, IBCs and bulk tankers
