What is Dibutylethanolamine?
Dibutylethanolamine (CAS 102-81-8), also known as DBEA, is a tertiary amine alcohol used in industrial formulations as a pH regulator, corrosion inhibitor, and emulsifier.
Where is Dibutylethanolamine used?
- Metalworking and cutting fluids: corrosion inhibitor and pH buffer protecting ferrous and non-ferrous surfaces during machining
- Textile and leather processing: emulsifier and dispersant in dyeing auxiliaries and finishing agents
- Water treatment: neutralizing amine controlling pH and inhibiting corrosion in cooling and boiler systems
- Paper manufacturing: supports sizing formulations and acts as a carrier solvent for surface treatment chemicals
- Its amine and hydroxyl functionality make it effective in aqueous and semi-aqueous systems.
Commercial specifications
- Technical grade, purity typically 99% or higher
- Clear to pale yellow liquid in drums and IBCs
- Tanker quantities for bulk procurement
