2-[(2-Aminoethyl)amino]ethanol · HEEDA · ≥ 99% commercial grade, LR and AR grades
Aminoethylethanolamine combines an ethyleneamine and an ethanolamine in one molecule — a primary amine, a secondary amine and a hydroxyl — and is the standard raw material for imidazoline softeners and corrosion inhibitors, HEDTA chelants and lubricant additives. Chelora Amines supplies it worldwide to fabric-care, oilfield, chelant, lubricant and resin producers across Asia, the Middle East, Africa, Europe and the Americas, as well as throughout India, with a batch-wise COA and SDS on every dispatch.
48.04 + 12.10 + 28.01 + 16.00 = 104.15 g/mol
Aminoethylethanolamine, usually shortened to AEEA and also called HEEDA, N-(2-hydroxyethyl)ethylenediamine or 2-[(2-aminoethyl)amino]ethanol, carries a primary amine, a secondary amine and a primary hydroxyl on a short chain. That makes it more reactive and more versatile than either an ethanolamine or a simple ethyleneamine.
It is a clear, colourless to pale yellow, viscous, hygroscopic liquid with a mild ammoniacal odour, boiling at about 240 °C and miscible with water. It absorbs carbon dioxide and water from the air, so sealed packing and nitrogen blanketing help keep colour and assay stable.
AEEA is made industrially either by reacting ethylenediamine with ethylene oxide, or as a co-product of ethyleneamine manufacture from monoethanolamine and ammonia; it is purified by vacuum distillation. Piperazine-type by-products, especially hydroxyethylpiperazine, are the impurities that specifications control.

Two different nitrogens and a hydroxyl explain what AEEA is used for: building imidazoline rings, amides and chelants, and curing resins. These are the jobs formulators and process chemists reach for it to do.
Condenses with fatty acids first to an amide, then with further heating and water removal to a 1-hydroxyethyl-2-alkyl imidazoline.
RCOOH + AEEA → imidazoline + 2 H₂OAt lower temperatures with fatty acids it stops at the amidoamine, an intermediate for softeners and asphalt emulsifiers.
RCOOH + AEEA → RCONHCH₂CH₂NHCH₂CH₂OHImidazolines and amidoamines from AEEA are quaternised to make cationic fabric softeners and hair conditioners.
imidazoline + R′X → imidazolinium saltReacts with formaldehyde and cyanide, or chloroacetic acid, to give hydroxyethylethylenediaminetriacetic acid, a chelating agent.
AEEA → HEDTAThe two amine nitrogens react with epoxy groups, so AEEA is used as or in epoxy hardeners and as a resin modifier.
R–NH₂ + epoxide → amino alcoholNeutralises acids and forms salts used in lubricant and fuel additives.
RCOOH + AEEA → saltImidazoline and amidoamine derivatives film metal surfaces, protecting pipelines and equipment in oilfield and refinery systems.
imidazoline film on steelUnder harsh conditions AEEA can cyclise to hydroxyethylpiperazine — the reason specifications cap piperazine-type impurities.
AEEA → HEP + H₂OProcess notes. Imidazoline synthesis needs good water removal and temperature control to convert the amide fully to the ring. AEEA is corrosive and can cause skin sensitisation — keep skin contact to a minimum. Keep drums closed to avoid CO₂ pick-up, which forms carbamate and raises colour.
Discuss your processAEEA is made by two related routes. Both explain why the specification controls piperazine-type by-products, related ethyleneamines, water and colour.
Either ethylenediamine is reacted with ethylene oxide, or monoethanolamine is aminated with ammonia over a catalyst.
The reaction runs under controlled temperature and pressure to favour AEEA over higher products.
The crude contains AEEA with ethyleneamines, hydroxyethylpiperazine and water.
A vacuum distillation train separates AEEA from lighter amines and heavier by-products.
AEEA is tested for purity, piperazines, water and colour, then filled into drums or totes under nitrogen.
The real quality question is "what else came with it". Hydroxyethylpiperazine and other cyclic amines do not form imidazolines properly, and water slows the cyclisation. Related ethyleneamines change the amine value and the product distribution in your reaction.
For softener and corrosion-inhibitor producers, a consistent amine value and low colour matter most. If your process is sensitive, say so at enquiry stage and we will match the batch.
In sealed original packing, stored cool and out of sunlight, AEEA is normally used within twelve months, and we recommend a re-check of assay and colour after that before a critical batch. Air and carbon dioxide ingress form carbamate and raise colour.
Keep drums closed between draws and blanket bulk tanks with dry nitrogen. A retained sample of each batch is held here, so any query can be tested against the original material.
Tell us the application and we will confirm the grade. Commercial grade covers softeners, corrosion inhibitors and chelants; LR and AR grades are available for laboratory work.
The everyday grade for imidazolines, amidoamines, HEDTA and lubricant additives.

Indicative specification for planning. The controlling document is the Certificate of Analysis issued for your batch. If your process needs tighter limits, say so at enquiry stage and we will quote against your specification.
Imidazoline and amidoamine producers choose between AEEA and polyethyleneamines such as DETA. The choice decides whether the product carries a hydroxyethyl or an aminoethyl side chain.
| Point of comparison | AEEA | Diethylenetriamine (DETA) |
|---|---|---|
| Side chain on the imidazoline | Hydroxyethyl | Aminoethyl |
| Best suited to | Fabric softeners, hair conditioners, oilfield corrosion inhibitors | Corrosion inhibitors, epoxy curing agents, polyamides |
| Further reaction after ring closure | Hydroxyl can be esterified or ethoxylated | Free amine can be amidated or quaternised |
| Volatility | Very low | Low |
| Typical colour of products | Paler | Can be darker |
AEEA sits between two better-known products: it carries the hydroxyethyl group of an ethanolamine and the two nitrogens of an ethyleneamine. That combination is why it forms imidazolines so readily.

Plan my supplyAminoethylethanolamine causes severe skin burns and eye damage, may cause an allergic skin reaction, and carries further health classifications listed on the SDS. The notes below are a summary for planning only — always work to the Safety Data Sheet supplied with your consignment and your own site risk assessment.
Aminoethylethanolamine is typically shipped as a Class 8 corrosive. That is routine for us, but it shapes the packing, labelling and paperwork before a first shipment moves.
| Item | Classification |
|---|---|
| Proper shipping name | Corrosive liquid, basic, organic, n.o.s. (2-(2-aminoethylamino)ethanol) — confirm on the SDS |
| UN number | Typically UN 3267 — confirm on the SDS for your batch |
| Hazard class | Class 8 (corrosive) |
| Packing group | III |
| Labels | Corrosion pictogram |
| Modes | Road, sea (IMDG) and air within dangerous goods quantity limits |
| Segregation | Away from acids, oxidisers and food-grade cargo |
Because AEEA is a dangerous good with health classifications, export bookings need correct UN packaging, labelling and a dangerous goods declaration, and some destinations require importer registration or inventory listing such as REACH. Tell us the destination at enquiry stage and we will confirm what is needed before the shipment is booked.

Aminoethylethanolamine is checked before dispatch and each consignment leaves with the paperwork your QC, stores and accounts teams need on day one.
The numbers on a Certificate of Analysis are only useful if you know how they were produced. These are the methods behind the figures on ours, and the checks worth repeating at your own goods-inward.
Separates aminoethylethanolamine from the related amines made in the same reactor, and gives the assay and impurity profile that matter most to your formulation.
An independent check on total amine content, useful as a quick goods-inward confirmation before a drum is released to production.
Water determination, which matters for anhydrous grades and confirms strength on aqueous grades.
A visual platinum–cobalt comparison. A rising colour value is the earliest sign that a pack has been exposed to air, heat or held too long.
Fast confirmation that the material is what the label says, and a simple way to spot dilution or the wrong pack.
Titration of total amine value confirms the active content that imidazoline and softener producers dose against.
A sample from every dispatched batch is held here, so a query months later can be settled against the original material rather than an argument.
Batch number on the label ties back to the COA, the test record and the supply lot, which is what your auditor will ask to see.
Where your customer or regulator needs an independent result, we can arrange analysis at a NABL-accredited laboratory before dispatch.

Aminoethylethanolamine is a commodity on a price list. What separates suppliers is grade flexibility, the paperwork and the answer you get when something is not routine.
Aminoethylethanolamine sits alongside more than fifty other amines we stock, from ethanolamines to fatty amines. Your purchase team raises one enquiry, compares one quote and manages one vendor record instead of six.
Different purities and supply forms of aminoethylethanolamine are available, so you are not forced to redesign a formulation around the only grade your supplier happens to carry.
COA, SDS, correct HSN and HS codes, transport declarations and certificates of origin are prepared with the consignment, not chased afterwards by your logistics team.
Tell us your limits on purity, related amines, water or colour and we quote against them, rather than sending the standard cut and letting your QC department find out.
Once we know your monthly draw we hold and release material on a schedule, so you carry less inventory than you otherwise would.
Describe the application rather than the product code and we will tell you which grade fits — and say so plainly when a different amine would serve you better.
