Disodium Phosphate (DSP) Supplier in Malaysia
- Also known as
- Disodium Hydrogen Phosphate
- Sodium Phosphate Dibasic
- Dibasic Sodium Phosphate
- Disodium Orthophosphate
Disodium phosphate supplier for food, water-treatment, cleaning and general industrial buyers in Malaysia. The same salt is traded as disodium hydrogen phosphate, sodium phosphate dibasic and DSP, with formula Na2HPO4 and CAS 7558-79-4 for the anhydrous material. Food-grade material is the additive sold as E339(ii).
Commercial options run from anhydrous powder and granules to dihydrate and dodecahydrate crystals, in technical, food and pharmaceutical grades. Anhydrous material carries the most phosphate per tonne, while the hydrates dissolve readily and suit solutions made up on site. State the form, hydrate and grade you work to so the offer matches your specification.
Food processors use disodium phosphate as a buffer, sequestrant and emulsifying salt in processed cheese, dairy, beverage, noodle and meat systems. Water treaters dose it for boiler and process-water conditioning, and cleaning formulators use it where controlled alkalinity is wanted rather than strong caustic alkalinity. Ceramics, textile dyeing and laboratory buffer preparation take the same salt.
Send the required form, grade, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

Disodium Phosphate 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 disodium phosphate (anhydrous) | white anhydrous powder or granules | — | Buffer, sequestrant and emulsifying salt (E339(ii)) in processed cheese, dairy, beverage, noodle and meat systems where pH control or protein dispersion is required. | Confirm the required pack format with the quotation. |
| Technical grade disodium phosphate (anhydrous) | white anhydrous powder | — | Boiler and process-water conditioning, alkaline cleaning blends and general industrial buffering where a food-additive specification is not needed. | Confirm the required pack format with the quotation. |
| Disodium phosphate dihydrate | colourless to white crystals | — | Solution make-up and process buffering where a hydrated crystal dissolves quickly and is straightforward to weigh out. | Confirm the required pack format with the quotation. |
| Disodium phosphate dodecahydrate | white crystalline solid (hydrated) | — | Long-established hydrate for baths and solutions mixed on site in cleaning, textile and dyeing operations. | Confirm the required pack format with the quotation. |
| Pharmaceutical and reagent grade | white crystalline powder | — | Buffer preparation, analytical work and formulation duties that call for a pharmacopoeial or reagent specification. | Confirm the required pack format with the quotation. |

Disodium Phosphate applications
Safety and handling
Store sealed in a cool, dry place and protect from moisture, which cakes the powder and hydrates anhydrous material. Control dust during handling, use gloves and eye protection, and rinse with water on contact. Follow the safety information issued for the quoted grade.
Common questions about disodium phosphate
Is disodium phosphate the same as disodium hydrogen phosphate?
Yes. Disodium hydrogen phosphate, sodium phosphate dibasic, disodium orthophosphate and DSP are all names for the same salt, Na2HPO4, supplied as additive E339(ii) in food grade. State the form and grade you need so the enquiry can be matched to the right commercial type.
How does disodium phosphate differ from monosodium and trisodium phosphate?
They are three separate sodium phosphates with different alkalinity. Monosodium phosphate (NaH2PO4) is acidic in solution, disodium phosphate (Na2HPO4) is mildly alkaline, and trisodium phosphate (Na3PO4) is strongly alkaline. Order the exact salt named on your specification, since a substitution shifts the pH of the whole system.
Which hydrate of disodium phosphate should I order?
Anhydrous powder carries the most phosphate per tonne and suits dry blending. The dihydrate and dodecahydrate hold water of crystallisation, dissolve quickly and are often specified where solutions are made up on site. Match the hydrate on your current specification, because a tonne of hydrate delivers less active salt.
Is food-grade disodium phosphate the same as technical grade?
Both are Na2HPO4. Food grade is controlled to food-additive expectations for E339(ii) use, while technical grade is specified for cleaning, boiler and general process duties. Check the documentation your application requires before treating one as a replacement for the other.
What is disodium phosphate used for in food processing?
It acts as a buffer, sequestrant and emulsifying salt: holding pH in dairy and beverage systems, dispersing protein in processed cheese, setting alkalinity in noodle dough and helping meat products retain moisture. Food grade is the material used as E339(ii).
What details are needed for a disodium phosphate price enquiry?
Provide the form or hydrate, the grade, the target specification, quantity and delivery location. Mention preferred packing and any documents your process requires so the quotation can address the full requirement.
