What N,N-Dimethylethanolamine is used for
N,N-Dimethylethanolamine (DMAE) is a colourless, viscous liquid with a fishy, ammoniacal odour, fully miscible with water. Both hydrogens on the amine nitrogen are replaced with methyl groups, making it a tertiary amine with no N–H bond — distinct in reactivity from the primary and secondary ethanolamines.
DMAE's largest application is as a curing agent for polyurethane and epoxy resin systems, where its tertiary amine catalyzes the curing reaction. It is also the feedstock for dimethylaminoethyl acrylate, an ester used as a flocculating agent in water treatment. Related N,N-dimethylethanolamine-derived compounds are used to remove hydrogen sulfide from sour gas streams, extending its relevance into gas-processing chemistry.
Where it sits among the ethanolamines
- Monoethanolamine primary amine — benchmark gas-treating amine. See that page.
- N-Methylethanolamine secondary amine, one methyl — intermediate and solvent chemistry. See that page.
- N,N-Dimethylethanolamine (this product) tertiary amine, two methyls — curing agent and flocculant-feedstock chemistry.
Appearance and handling character
DMAE is both flammable and corrosive — harmful if swallowed or inhaled, harmful in contact with skin, and causes severe skin burns and eye damage — a dual hazard profile that calls for careful ignition-source control alongside standard corrosive-liquid handling.

How we supply N,N-Dimethylethanolamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. DMAE's flammability adds a layer of logistics planning that other alkanolamines in our range don't need — that shapes how we manage this line.
We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- Assay and amine value confirmed before we quote. Curing performance in polyurethane and epoxy systems is sensitive to purity.
- Flammable-liquid logistics managed end to end. Classification, labelling and carrier compliance confirmed before booking.
- UN 2051 documentation filed correctly. Every shipment carries the correct hazard declarations.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your plant's consumption calendar.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.

Flammable and corrosive — a dual hazard profile
DMAE's combination of flammability and corrosivity means both ignition control and skin/eye protection matter in routine handling. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H226Flammable liquid and vapour.H302Harmful if swallowed.H312Harmful in contact with skin.H314Causes severe skin burns and eye damage.H332Harmful if inhaled.
Always read the SDS issued with your specific batch. Eliminate ignition sources; handle with chemical-resistant gloves, splash goggles and adequate ventilation.
Storage
Store in tightly closed containers away from heat, sparks and open flame, in a well-ventilated area rated for flammable liquids.
Handling
Use with local exhaust ventilation and bond/ground equipment during transfer to control static discharge. Avoid skin and eye contact; have emergency eyewash and safety-shower provision nearby.
Transport
Shipped under UN 2051, Class 3 with subsidiary hazard 8 (flammable, corrosive). We confirm and document packing group and exact classification for your specific shipment and destination.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Assay and amine value confirmed against your curing-system requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and transport paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How N,N-dimethylethanolamine is made
N,N-Dimethylethanolamine is produced industrially by the reaction of ethylene oxide with dimethylamine, a route that delivers the fully N,N-dimethylated tertiary product directly, followed by purification and fractional distillation.
We do not publish operating process parameters here; this is background only. Full technical and safety documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
