Ethylenediamine (EDA) Supplier in Malaysia
- Also known as
- Ethylene Diamine
- EDA
- 1,2-Diaminoethane
- Ethane-1,2-Diamine
Ethylenediamine supplier for epoxy, surfactant, water-treatment and chemical synthesis buyers in Malaysia. Also written ethylene diamine and abbreviated EDA, with the systematic names 1,2-diaminoethane and ethane-1,2-diamine, it is a clear alkaline liquid of formula C2H8N2 with a strong amine odour. It is the diamine raw material, not the solid chelating acid EDTA that is made from it.
Commercial choice is between anhydrous high-assay liquid, commonly quoted at 99% minimum, and aqueous solutions at strengths such as 70% and 80%. Those solutions are genuine traded grades rather than dilutions made to order, so state the strength your process needs and compare offers on active content.
Buyers use ethylenediamine for epoxy curing agents and hardeners, chelating-agent manufacture, cationic surfactants and fabric softener actives, corrosion inhibitors and neutralising amine blends, and agrochemical and pharmaceutical intermediates. Diethylenetriamine, triethylenetetramine and the higher ethyleneamines are separate products quoted by their own names.
Send the required grade or solution strength, specification, quantity and delivery location with your enquiry. Availability, packing, documentation, route and timing are confirmed with the quotation, and supply is subject to applicable requirements.

Ethylenediamine grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Anhydrous ethylenediamine | clear, colourless to pale yellow liquid | high-assay anhydrous grade, commonly quoted at 99% minimum | Epoxy curing agents and hardener blending, and chelating-agent synthesis where the reaction charge is calculated on undiluted diamine and added water would interfere. | Drum, IBC or bulk tank format is confirmed with the quotation against the quantity enquired for. |
| Ethylenediamine 80% aqueous solution | clear aqueous solution | nominal 80% ethylenediamine in water | Fabric softener, cationic surfactant and amide manufacture where a pumpable solution is easier to meter into a batch than the anhydrous liquid. | Drum, IBC or tank format is confirmed with the quotation. |
| Ethylenediamine 70% aqueous solution | clear aqueous solution | nominal 70% ethylenediamine in water | Corrosion-inhibitor and boiler-water blending, and neutralising-amine duties where the diamine is dosed dilute and lower vapour on opening a drum is preferred. | Drum or IBC format is confirmed with the quotation. |

Ethylenediamine applications
Safety and handling
- Classification
- flammable, irritant
Ethylenediamine is a flammable alkaline liquid and its vapour irritates the eyes, skin and respiratory tract, more noticeably from the anhydrous grade than from a dilute solution. Store closed containers in a cool, shaded, well-ventilated area away from heat, ignition sources, acids and oxidising agents, and handle with ventilation, gloves and eye protection as set out in the safety information for the grade quoted. Supply is subject to applicable requirements.
Common questions about ethylenediamine
Are ethylenediamine, ethylene diamine and EDA the same product?
Yes. The joined and spaced spellings describe the same diamine, formula C2H8N2, and EDA is its established trade abbreviation. The systematic names 1,2-diaminoethane and ethane-1,2-diamine appear on specification sheets for the same material.
Is ethylenediamine the same as EDTA?
No, they are separate products. Ethylenediamine is the simple liquid diamine, while the chelating acid and its sodium salts are solid downstream materials manufactured from it. If your formulation calls for a chelant, order the chelating product by name and enquire for it separately.
Is diethylenetriamine or triethylenetetramine a grade of ethylenediamine?
No. DETA and TETA are longer ethyleneamines with more nitrogen atoms per molecule, different reactivity and different specifications, and each is quoted as its own product by name. Higher amines such as TEPA sit in the same family but are not interchangeable with the diamine.
Should I order anhydrous ethylenediamine or an aqueous solution?
Choose anhydrous high-assay liquid when the reaction charge is calculated on undiluted diamine and added water would interfere, as in most epoxy hardener and synthesis work. Aqueous grades around 70% and 80% suit dosing into formulations that already contain water.
Why is ethylenediamine traded as an aqueous solution at all?
The anhydrous liquid solidifies a little above 8 degrees Celsius and gives off a stronger amine vapour when a container is opened, so a solution is easier to pump, meter and handle in a blending plant. Solution strength is stated on the enquiry so active content can be compared properly.
What packing is ethylenediamine supplied in?
Both the anhydrous grade and the aqueous solutions are liquids, so they move in drums, IBCs and bulk tank arrangements according to volume. The pack format for your quantity is confirmed with the quotation along with documentation.
What details are needed for an ethylenediamine price enquiry?
Give the grade or solution strength, quantity, intended application, preferred pack format and delivery location. Note any assay, colour or water limit and any document requirement so the quotation addresses the complete requirement.
