About this product
Di Ethanol Amine (DEA), CAS 111-42-2, is the two-hydroxyethyl member of the ethanolamine family — a secondary amine carrying two hydroxyl groups. That structure is why diethanolamine works as a base, as an acid-gas absorbent and as a chemical intermediate. We import Industrial Grade material (99.0% min) from PETRONAS Chemicals Marketing (Labuan) Ltd in Malaysia and hold it in steel drums of 228 kg net at our Redhills warehouse in Chennai, with dispatch across South India. TDS and MSDS are available for download; spec values are indicative and the batch COA governs.

Frequently Asked Questions
What is diethanolamine (DEA) used for, and what does DEA stand for?
DEA is the standard industry abbreviation for diethanolamine, also written di-ethanol amine and systematically as 2,2'-iminodiethanol or bis(2-hydroxyethyl)amine. It is a secondary amine and an ethanolamine (amino alcohol), carrying one amine group and two hydroxyl groups. That structure makes it useful as a base, as an acid-gas absorbent in scrubbing systems, and as an intermediate for surfactants, metalworking fluids and other downstream chemistry. We supply Industrial Grade (99.0% min) DEA from Chennai stock.
What is the CAS number and HSN code for diethanolamine?
Diethanolamine is CAS 111-42-2. The HSN / HS code we declare is 2922 12 00.
What is the difference between MEA, DEA and TEA?
MEA (CAS 141-43-5), DEA (CAS 111-42-2) and TEA (CAS 102-71-6) are the three ethanolamines, carrying one, two and three hydroxyethyl groups respectively. We stock all three in Chennai, with TEA available in 85% and 99% grades.
What grade and specification of diethanolamine do you supply?
We supply Industrial Grade (99.0% min). Indicative specs: diethanolamine 99.0 – 100.0 % wt, monoethanolamine 0.5 % wt max, triethanolamine 0.5 % wt max, water 0.15 % wt max, colour 15 max Pt-Co, appearance clear liquid. These values come from the manufacturer's certificate of analysis (PETRONAS) and are indicative — the batch COA governs. TDS and MSDS PDFs are available for download on this page.
Where can I buy diethanolamine in Chennai, and what packaging is available?
We import DEA directly from PETRONAS Chemicals Marketing (Labuan) Ltd, Malaysia, and dispatch from our Redhills, Chennai warehouse across South India. Packaging is steel drums, 228 kg net. Order sizes depend on packaging and current stock — call or WhatsApp +91 86087 80096 for a quote.
Is diethanolamine hygroscopic, and how should it be stored and handled?
Yes — DEA is hygroscopic, and it causes skin and serious eye irritation. Store it sealed in a cool, dry, well-ventilated area away from acids and oxidisers, and wear gloves and eye protection when handling.
