Triisopropanolamine (CAS 122-20-3, C9H21NO3) is a trifunctional amino-alcohol, often supplied as an aqueous solution. It is used as an emulsifier, a corrosion inhibitor in metalworking fluids, a cross-linking agent in coatings and rubber, and a neutralizer/acid-acceptor.

Frequently Asked Questions

What is triisopropanolamine used for?

Triisopropanolamine (TIPA, CAS 122-20-3, C9H21NO3) is a trifunctional amino-alcohol used as an emulsifier and solubilizing agent, a corrosion inhibitor and surfactant in metalworking fluids, a cross-linking agent in coatings and rubber, and a neutralizer/acid-acceptor.

What is the 85% in triisopropanolamine LFG 85?

TIPA is commonly supplied as an aqueous solution; the 85% designation refers to a TIPA concentration grade (the balance being water). RawSource confirms the exact assay against the CoA at the time of quote.

Is triisopropanolamine an acid or a base?

Triisopropanolamine is a weak base (an amino-alcohol). This is why it is used as a neutralizer and acid-acceptor and as an alkalinity source in metalworking and coating formulations.

What is the HS code and formula for triisopropanolamine?

Triisopropanolamine has formula C9H21NO3 and CAS 122-20-3, classified under HS code 2922.19 (other amino-alcohols, their ethers and esters).

How do I get a bulk quote and shipping documentation for TIPA 85%?

RawSource supplies triisopropanolamine LFG 85% in industrial bulk. It ships under UN 3259; request a quote for your volume and packaging, and we will provide the SDS and CoA along with applicable shipping documentation.
