Tetrasodium HEDP Supplier Malaysia
- Also known as
- HEDP Na4
- HEDP 4Na
- Tetrasodium Etidronate
- HEDP Tetrasodium Salt
Tetrasodium HEDP is the fully neutralised sodium salt of 1-hydroxyethylidene-1,1-diphosphonic acid and is also known as HEDP Na4, HEDP 4Na and tetrasodium etidronate. Buyers seeking a tetrasodium HEDP supplier in Malaysia should specify the salt form rather than using bare HEDP where the acid and sodium salts could be confused.
Genuine market forms include an aqueous solution at a stated active concentration and a spray-dried solid grade. The salt is selected where a near-neutral to alkaline organophosphonate form is preferred over the acidic HEDP solution, with concentration and other quality parameters confirmed against the buyer's specification.
Tetrasodium HEDP is used as a chelant and scale-control component in cooling-water, boiler-water and reverse-osmosis formulations. It is also used in detergents and cleaners, peroxide-stabilisation systems, textile bleaching and selected metal surface-treatment formulations.
This page covers only the tetrasodium salt and does not merge HEDP acid, disodium or trisodium HEDP, ATMP, PBTC, EDTA or polyacrylate dispersants into the same identity. Send the required solution concentration or solid form, specification, quantity and delivery location for a quotation.

Tetrasodium HEDP applications
Common questions about tetrasodium HEDP
What is tetrasodium HEDP used for?
It is used as an organophosphonate chelant and scale-control component in water treatment, detergents, cleaners, textile processing and metal surface-treatment formulations.
Is tetrasodium HEDP the same as HEDP acid?
No. Tetrasodium HEDP is the fully neutralised sodium salt, while HEDP acid is the acidic free-acid form and should be specified separately.
Are HEDP Na4, HEDP 4Na and tetrasodium etidronate the same product identity?
Yes. These names refer to the tetrasodium salt, subject to confirmation of the physical form and active concentration required.
Does this page include disodium or trisodium HEDP?
No. Disodium and trisodium HEDP are different salt forms and should not be substituted for the tetrasodium grade without formulation review.
What information is needed for a quotation?
Provide the solution concentration or solid form, specification, quantity, delivery location and required documents. Availability, packing and the document set are confirmed with the quotation.
