Sodium Hexametaphosphate
CAS 10124-56-8(NaPO3)6611.77 g/mol
Sodium Hexametaphosphate (SHMP) is predominantly used in water treatment to act as a sequestrant and scale inhibitor. It also plays crucial roles in industries like food processing, ceramics, and detergents. This white crystalline powder helps enhance cleaning by sequestering hard ions and improving water softening. Its high phosphate content makes it essential in maintaining equipment and improving product quality across water treatment systems, processed foods, industrial cleaning processes, and even in clay dispersion for ceramics. SHMP is readily available in Kenya, typically supplied in 25 kg bags.
Main applicationWater treatment — sequestrant and scale inhibitor
Sodium Hexametaphosphate is significant due to its versatility in enhancing water treatment processes and facilitating product improvement in food, ceramics, and detergents. Its ability to inhibit scale and soften water preserves equipment efficiency, reducing maintenance costs and extending lifecycles. In food production, it ensures quality and consistency, making it an indispensable staple for manufacturers.

Sodium Hexametaphosphate, with the molecular formula (NaPO3)6 and a molecular weight of approximately 611.77 g/mol, is a polyphosphate commonly supplied in a white crystalline powder form. Its typical phosphate content, measured as P2O5, is no less than 68%. This high purity makes it effective for industrial and food grade applications, where inactive phosphate levels are below 7.5%, ensuring minimal impurities in sensitive processes. Buyers must note specifications like water-insoluble content, pH range, and iron levels for suitability in food applications. When ordering for specific uses, technical grade considerations may include PH value and heavy metal content, crucial in stringent regulatory environments.

Frequently asked questions
What is the CAS number of Sodium Hexametaphosphate?
The CAS registry number for Sodium Hexametaphosphate is 10124-56-8. Its chemical formula is (NaPO3)6, with a molecular weight of 611.77 g/mol. Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.
What are the other names for Sodium Hexametaphosphate?
Sodium Hexametaphosphate is also referred to as SHMP, Sodium Hex and Calgon. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.
What grade of Sodium Hexametaphosphate is supplied?
Sodium Hexametaphosphate is supplied as Technical grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.
What concentration is Sodium Hexametaphosphate supplied at?
Sodium Hexametaphosphate is supplied at a concentration of 68 % P2O5. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.
What is the purity of Sodium Hexametaphosphate?
The purity/assay figure recorded for Sodium Hexametaphosphate is 68%. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.
What does Sodium Hexametaphosphate look like?
Sodium Hexametaphosphate is described as white crystalline powder. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.
What is Sodium Hexametaphosphate used for?
Common applications include water treatment — sequestrant and scale inhibitor, food processing — emulsifier and texture stabilizer, ceramics — deflocculant to improve slurry, detergents — ion sequestrant to enhance cleaning, electroplating — complexing agent in plating and construction — water reducer for concrete. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.
Which industries use Sodium Hexametaphosphate?
Sodium Hexametaphosphate is supplied to the Water Treatment, Food Processing & Beverage, Cleaning & Detergents, Paints, Coatings & Inks and Textile & Leather Tanning sectors. These are the industries this product is listed against in our catalogue; if your application falls outside them, we can advise on suitability before you order.
What packaging is Sodium Hexametaphosphate available in?
Available in 25 kg bags. Where a different pack size or bulk delivery is required, it is confirmed at quotation stage against availability rather than listed here as standard.
What is the HS code for Sodium Hexametaphosphate?
Sodium Hexametaphosphate is recorded against the HS customs code 2835 3919. Quote this on customs and export paperwork; it is confirmed again on the commercial invoice for your specific consignment.
