Sodium Diacetate (SDA) Supplier in Malaysia
- Also known as
- SDA
- Sodium Hydrogen Diacetate
- Sodium Acid Acetate
- E262(ii)
Sodium diacetate supplier for food manufacturers, meat processors, feed mills and industrial buyers in Malaysia. Sold as SDA, sodium hydrogen diacetate, sodium acid acetate and the additive code E262(ii), it carries CAS 126-96-5 and is written NaH(C2H3O2)2. The material is a dry molecular complex of sodium acetate and acetic acid, which is why the powder smells of vinegar.
Its commercial appeal is that it puts an acid into a weighable free-flowing solid. Bakeries use it against mould and rope, snack and sauce producers use it as a dry acidulant that gives a vinegar note without adding liquid, and feed mills dose it as a solid acidifier in compound feed, premixes and silage programmes.
Grades run food, feed and technical, separated mainly by the free acetic acid content and the impurity and flow limits a plant works to. Standard material is a free-flowing crystalline powder; encapsulated grades carry a coating so the acid is not released during mixing, which is why meat and poultry lines ask for them.
Send the grade, standard or encapsulated form, target specification, quantity and delivery location with your enquiry. Availability, pack format, documentation and timing are confirmed with the quotation.

Sodium Diacetate 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 |
|---|---|---|---|---|
| Food grade sodium diacetate (E262(ii)) | free-flowing crystalline powder | — | Bread and bakery formulations working against mould and rope, plus sauces, dressings and dry seasoning blends that want a vinegar note in dry form. | Confirm the required pack format with the quotation. |
| Encapsulated sodium diacetate | coated free-flowing granular solid | — | Meat and poultry processing where the coating holds the acid back during mixing so it is not released until later in the process step. | Confirm the required pack format with the quotation. |
| Feed grade sodium diacetate | crystalline powder or granules | — | Acidifier in compound feed and premixes, and silage treatment programmes that need a dry acid source rather than a liquid one. | Confirm the required pack format with the quotation. |
| Technical grade sodium diacetate | crystalline powder | — | Buffering and acidity adjustment in agricultural and industrial formulation work outside food and feed programmes. | Confirm the required pack format with the quotation. |

Safety and handling
Keep containers closed in a cool, dry, ventilated store away from strong alkalis, and expect a noticeable acetic smell when packs are opened. Follow the safety information issued for the quoted grade.
Common questions about sodium diacetate
What is sodium diacetate, and is SDA the same thing?
It is a dry molecular complex of sodium acetate and acetic acid, supplied as a white crystalline powder that smells of vinegar. SDA, sodium hydrogen diacetate and sodium acid acetate all name this same material, and E262(ii) is its additive identity code.
Is sodium diacetate the same as sodium acetate?
No, they are different products. Sodium acetate is the simple salt and sits under E262(i), while this material combines that salt with acetic acid in one solid and is identified as E262(ii). Order the one your formulation names by name, because the free acid content is what separates them.
Why use sodium diacetate instead of liquid acetic acid or vinegar?
It puts the acetate and the free acid into a weighable free-flowing solid, which suits dry seasoning blends, bakery premixes and feed lines that have no practical way to handle or dose an acid liquid. State the form the plant can feed and the specification it works to.
What does encapsulated sodium diacetate offer over the standard powder?
The coating keeps the acid from being released during mixing, so processors running meat and poultry formulations can blend it in and have it act later in the step. Standard powder remains the choice for bakery, seasoning and feed work where immediate availability is fine.
How is sodium diacetate different from sorbate, benzoate or propionate preservatives?
Those are separate products with their own identities, specifications and working pH ranges, so they are not interchangeable on a label or in a recipe. Sodium diacetate is the acetate-based option and carries an acetic odour that the others do not. Request the preservative your formulation specifies.
Which grade and specification should a sodium diacetate enquiry state?
Name the food, feed or technical grade, say whether standard or encapsulated material is needed, and give the assay, free acetic acid content, moisture and particle size limits that apply. Add the quantity, delivery location and any documents your quality system needs. Supply is subject to applicable requirements.
