Description

Sodium Hexametaphosphate (SHMP) is one of the most widely used polyphosphates in the food, water treatment, detergent, and ceramic industries. With the chemical formula (NaPO₃)₆ and the food additive code E452(i), it functions as a chelating agent, moisture-retention agent, and emulsifier.

Sepidstan Tejarat, a direct importer of chemical raw materials, supplies Sandia® Sodium Hexametaphosphate in both Food Grade and Industrial Grade.

In this guide, we answer the most common questions buyers have regarding the applications, food-grade specifications, pricing, and purchasing of Sodium Hexametaphosphate from a trusted importer.

What Is Sodium Hexametaphosphate?

Sodium Hexametaphosphate, also known as SHMP, Graham’s Salt, or Sodium Metaphosphate, is a water-soluble phosphate polymer. It is supplied as a white glassy powder or granular material with excellent solubility in water.

Its most important characteristic is its strong ability to chelate metal ions such as calcium, magnesium, and iron. This property makes SHMP highly effective for water softening, scale prevention, and product stabilization across many industries.

Applications of Sodium Hexametaphosphate

SHMP has a wide range of industrial and food applications, including:

• Food Industry: Moisture retention in meat, poultry, and seafood products; stabilization of processed cheese; texture improvement and emulsification in dairy products and canned foods.
• Water Treatment: Prevention of scale formation in boilers, cooling towers, and industrial water systems.
• Detergents & Cleaning Products: Improves cleaning efficiency by softening hard water and preventing mineral deposits.
• Ceramics & Tiles: Used as a dispersing agent to reduce slurry viscosity.
• Textile, Paint, and Drilling Industries: Functions as a dispersant and scale-control agent.

Sodium Hexametaphosphate in Detergent Formulations

Sodium Hexametaphosphate is a key ingredient in household and industrial detergent formulations. Acting as a water softener and metal ion sequestrant, it binds calcium and magnesium ions present in hard water, preventing scale formation and improving the effectiveness of surfactants.

Its use provides several advantages:

• Enhanced cleaning performance
• Prevention of stains and mineral deposits
• Improved formulation stability
• Higher efficiency under hard-water conditions

For these reasons, SHMP is widely used in laundry detergents, liquid cleaners, industrial cleaning products, and various sanitation formulations.

What Is Food-Grade Sodium Hexametaphosphate?

Food-grade Sodium Hexametaphosphate is manufactured in accordance with E452(i) food additive standards and contains heavy metals and impurities within the permitted limits for human consumption.

Typical food applications include:

• Moisture retention and texture improvement in meat, poultry, and seafood
• Stabilization and texture enhancement in cheese and dairy products
• pH adjustment and emulsification in beverages and canned foods

In food formulations, SHMP is often used alongside other approved food additives such as Sorbitol (as a humectant and low-calorie sweetener) and Propylene Glycol (as a solvent and carrier), both of which are also supplied by Sepidstan Tejarat.

Important: Only certified Food Grade SHMP with a valid Certificate of Analysis (COA) should be used in food applications.

Food Grade vs. Industrial Grade Sodium Hexametaphosphate

Feature	Food Grade	Industrial Grade
Purity & Impurity Control	Higher, compliant with food standards	Industrial standard
Heavy Metal Content	Within food safety limits	Less stringent control
Main Applications	Food processing	Water treatment, detergents, ceramics
Certification	COA and food safety documentation	Industrial COA

Selecting the correct grade depends on the intended application. Industrial-grade SHMP must never be used in food products.

Sodium Hexametaphosphate Price

As an imported chemical, the price of Sodium Hexametaphosphate is influenced by several factors:

• Product grade (Food Grade or Industrial Grade)
• Purity level and P₂O₅ content
• Order quantity
• Packaging type (typically 25 kg bags)
• Exchange rate fluctuations and market conditions

Because prices change according to daily market conditions and currency rates, please contact Sepidstan Tejarat for the latest quotation and bulk purchase pricing.
