What is Triisopropanolamine?
Triisopropanolamine (CAS 122-20-3), commonly abbreviated as TIPA, is a tertiary alkanolamine used as a pH regulator, chelating agent, and crosslinker.
Where is Triisopropanolamine used?
- Coatings and adhesives: crosslinking agent and curing accelerator
- Alkyd and epoxy systems: improves film hardness and adhesion
- Personal care: neutralizes carbomer and acrylate polymers, adjusting pH in creams, lotions, and gels
- Water treatment: chelating capacity sequesters calcium and magnesium ions, preventing scale formation in industrial process water
- Textile and leather processing: pH buffer and auxiliary agent during dyeing and finishing operations
- Its dual amine-alcohol functionality neutralizes acidic systems and coordinates metal ions.
Commercial specifications
- Purity levels typically at 85% and 99%
- Bulk supply in drums and IBC containers
