Description
Diisopropanolamine (DIPA, CAS 110-97-4) is a secondary alkanolamine also known as iminodipropanol, di-2-propanolamine, and bis(2-propanol)amine. It carries no assigned E-code and is classified under EC 203-820-9. The molecule combines amine and hydroxyl functionality within a single structure.
In coatings and adhesives, DIPA acts as a crosslinker by reacting with isocyanates or epoxy resins to extend polymer networks and improve film integrity. In personal care formulations, it neutralizes acidic ingredients to adjust pH and functions as a humectant, drawing moisture to the skin. Water treatment applications exploit its buffering capacity to stabilize process chemistry within defined pH ranges.
DIPA is supplied as a low-melting solid and is available in technical and cosmetic-grade specifications. It falls under REACH registration requirements for EU supply. Standard packaging includes drums and IBC containers, with documentation available to support COSMOS and ISO 16128 compliance assessments for personal care applications.
