Properties and stability
Chemical properties are similar to triethanolamine. Isopropyl alcohol is formed during reduction with Raney nickel.
Storage method
None
Synthesis method
Produced by the reaction of propylene oxide and ammonia, it is a co-product of the production of isopropanolamine.
Purpose
Used as pharmaceutical raw materials and photographic developer solvents. Used as a solvent for paraffin oil in the man-made fiber industry. Since the salts formed by triisopropanolamine and long-chain fatty acids have good coloring stability, they are particularly suitable as emulsifiers for cosmetics.
