What is Diisopropanolamine?
Diisopropanolamine (CAS 110-97-4), commonly abbreviated as DIPA, is a secondary alkanolamine.
Where is Diisopropanolamine used?
- Coatings and industrial fluids: neutralizes acidic resins and dispersants to stabilize emulsions
- Adhesives and sealants: crosslinking agent and curing accelerator in polyurethane and epoxy systems
- Water treatment: scavenges acidic gases such as CO₂ and H₂S in gas purification
- Personal care: neutralizes carbomers and anionic polymers in creams, lotions and hair care products
- It functions as a pH regulator, neutralizing agent and curing component.
Good to know: Procurement teams source it as a cost-effective alternative to triethanolamine where lower viscosity or different reactivity profiles are required. It adjusts pH without the odor concerns associated with some competing amines.
Commercial specifications
- Cosmetic-grade material meeting relevant purity specifications for personal care
