EDTA (Ethylenediaminetetraacetic Acid) Supplier in Malaysia
- Also known as
- Ethylenediaminetetraacetic Acid
- Disodium EDTA
- Tetrasodium EDTA
- Chelating Agent
ChemTrade supplies EDTA to detergent, water treatment, cosmetic, food and fertiliser manufacturers across Malaysia. We carry it as the disodium and tetrasodium salts, the free acid, food grade calcium disodium, and the iron, zinc, manganese and copper chelates. Chinese, Korean and European material is available depending on the salt.
Which salt you order is the only real decision, and it comes down to pH and solubility. Disodium dissolves to around 100 g/L and holds a solution at pH 4.3 to 4.7. Tetrasodium is far more soluble and strongly alkaline, which is why alkaline cleaner concentrates use it.
The free acid is only 0.5 g/L soluble and suits formulators who neutralise it in the batch themselves. Calcium disodium is the E385 food additive grade, with the calcium already bound so it will not strip it out of the product. Send us the pH your formulation runs at and we will name the salt.
No poisons licence is needed for any grade, and none of them is regulated as dangerous goods for transport, so EDTA moves as general cargo. The powder does cause serious eye damage though, so goggles rather than safety glasses when bags are charged by hand.

EDTA 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 |
|---|---|---|---|---|
| Disodium EDTA | white crystalline powder | ≥ 99% | The default where the finished product must stay near neutral or acidic. It dissolves to around 100 g/L and its solution sits at pH 4.3 to 4.7, so it goes into cosmetic emulsions, shampoo and liquid soap as a preservative booster, and into food and beverage to hold trace iron and copper away from colour and flavour. | 25 kg bag |
| Tetrasodium EDTA | white powder or granules | — | The fully neutralised salt, far more soluble than the disodium and strongly alkaline in solution. That suits alkaline detergent and industrial cleaner concentrates, where the disodium would drag the pH down and can salt out of a heavily built formulation. | 25 kg bag |
| EDTA acid | white crystalline powder | — | The free acid, only 0.5 g/L soluble in water, so it is dosed where the sodium load matters or where the formulator neutralises it in the batch with their own alkali. Also the reference material for hardness titration. | 25 kg bag |
| Calcium disodium EDTA | white crystalline powder | 98 to 102% | The food additive grade, E385, used in dressings, canned seafood, sauces and soft drinks. The calcium is already bound, so it sequesters iron and copper without stripping calcium out of the product. | 25 kg bag |
| EDTA metal chelates | powder, 10 to 14% metal | — | Iron, zinc, manganese and copper chelates for foliar feed, fertigation and micronutrient blends. The chelate keeps the metal plant available in a soil or tank mix where a sulphate would precipitate. | 25 kg bag or carton |
| Analytical reagent disodium EDTA | crystalline powder | — | Reagent grade for complexometric titration of water hardness and for laboratory buffers, in a small pack so an occasional user is not buying a bag. | 500 g bottle |

EDTA applications
Safety and handling
- Classification
- causes serious eye damage, harmful if swallowed, may cause damage to organs through prolonged or repeated exposure
Store sealed in a cool, dry place. The powders are dusty and the dust is what causes the eye injuries, so charge bags with goggles on rather than safety glasses, and use local extraction where the transfer is repeated. Wash hands before eating. Solutions attack nothing in normal plant materials, but EDTA will strip metal from an alloy surface given time and heat, so do not store a concentrated solution in a galvanised or copper vessel.
Common questions about EDTA
Which EDTA salt should I order?
Match it to your pH and your solubility need. Disodium dissolves to about 100 g/L and takes a solution to pH 4.3 to 4.7, so it suits neutral and acidic products. Tetrasodium is far more soluble and strongly alkaline, which is what alkaline cleaner concentrates need. The free acid is barely soluble at 0.5 g/L and is for formulators who neutralise it themselves. Tell us the formulation pH and we will pick it.
Can you supply food grade EDTA?
Yes, calcium disodium EDTA to the E385 food additive specification, in 25 kg bags. Specify food grade when you enquire and it ships with the producer's documentation for the batch quoted. Tell us if your audit also needs halal certification and we will confirm what the producer holds before you commit.
What assay and impurity levels do you supply?
Disodium runs at 99% minimum on the dried basis with a chelation value of at least 265 mg CaCO3 per gram, and the food grade calcium disodium at 98 to 102%. If your process has a tighter limit on nitrilotriacetic acid, heavy metals or chloride, send the specification and we will source against it rather than send you the nearest thing.
What is the difference between EDTA and a phosphate builder?
EDTA binds the metal into a soluble complex at a one to one molar ratio, so it works across a wide pH band and stays effective at low dose. A phosphate builder mainly precipitates or exchanges hardness, is cheaper by weight, and is restricted in some effluent regimes. Formulators often use both, and we supply the phosphates as well.
Do I need a licence to buy EDTA in Malaysia?
No. EDTA is not a scheduled poison here and none of the grades we carry requires a purchase licence or permit, unlike several other chelants and alkalis in our range. Normal commercial terms apply, and the food grade is the only one where documentation is part of the transaction.
Is it classed as dangerous goods for transport?
No. The sodium salts are not regulated as dangerous goods, so they move as general cargo by road and by sea with no dangerous goods declaration. That does not make the powder harmless to handle: it causes serious eye damage, so goggles rather than safety glasses when charging bags.
Which grade do I use for a hardness titration?
The analytical reagent disodium salt, in a 500 g bottle rather than a bag. It is dried and standardised for complexometric work, which is what a 99% industrial grade is not. Ask for reagent grade when you enquire so it is not quoted against the bulk line.
What packing is available?
25 kg bags across every salt, cartons on the metal chelates, 1 kg bags and 500 g bottles for laboratory quantities. We buy from several producers, so if your handling needs a different bag weight or a pallet configuration, ask.
