Sodium Hexametaphosphate(SHMP)

Sodium hexametaphosphate (SHMP, (NaPO₃)₆) is a colorless, transparent, glassy solid or white powder that is highly soluble in water, forming a weakly acidic aqueous solution. Industrially produced by high-temperature polymerization of sodium dihydrogen phosphate. Its primary applications include food additives (water retention, thickening), water treatment agents (water softening, scale inhibition), and detergent auxiliaries. It is also used in mineral processing, papermaking, and other fields. Store in sealed containers to prevent moisture absorption, keep away from high temperatures, and avoid inhaling dust during handling.

Basic Properties

1. Physical Properties:

Appearance: White powder or colorless transparent glass flakes.

Solubility: Easily soluble in water; aqueous solution is alkaline.

Hygroscopicity: Strongly hygroscopic; gradually deliquesces in humid air.

Melting Point: Approximately 616°C (decomposes).


2. Chemical Properties (Core Functions):

Chondralization: This is SHMP's most important property. It can form stable, soluble complexes with metal ions such as calcium (Ca²⁺), magnesium (Mg²⁺), and iron (Fe²⁺/³⁺) in water. This makes it an excellent water softener and scale inhibitor.

Dispersing Effect: It can adsorb onto the surface of solid particles, increasing their surface charge, thereby preventing particle aggregation and deposition, resulting in good dispersion. This is crucial for preventing fouling and maintaining particle suspension.

Buffering Effect: It has a certain buffering capacity for the pH of the system, maintaining the solution in a slightly alkaline range.

Protein volume-enhancing effect: In meat processing, it can dissociate actomyosin, increasing the water-holding and oil-holding capacity of proteins, thereby improving the tenderness and yield of the product.

pH adjustment: The pH value of its 1% aqueous solution is approximately 6.0-7.6.

Main Applications

1. Water Treatment Industry

  • Scale Inhibitors: Effectively prevent the formation of scale such as calcium carbonate and calcium sulfate in boilers, cooling towers, and heat exchangers by chelating with scale-forming ions (e.g., Ca²⁺).

  • Corrosion Inhibitors: In metal pipes and equipment, remove corrosion-promoting metal ions through chelation, thus inhibiting corrosion.

  • Water Softeners: Used in industrial laundry, printing and dyeing, etc., to soften water and improve washing performance.

2. Food Industry (as a food additive, INS number 452i)

  • Moisture Retention Agents: Widely used in meat products (e.g., ham, sausage, fish balls), poultry products, and seafood to improve water retention, resulting in a smoother texture and reduced weight loss during processing.

  • Quality Improvers: Used in dairy products, soy sauce, beverages, etc., to prevent protein coagulation and precipitation, stabilizing the system.

  • Chlorinating Agents: Used in canned goods and fruit juices to chelate metal ions, preventing discoloration, off-flavors, and oxidative spoilage, extending shelf life.

  • pH adjusters and leavening agents: Used in baked goods and powdered beverages.

3. Detergents and cleaning products

  • Building agents: Once an important component of synthetic detergents (such as laundry powder), they enhance the cleaning effect of surfactants and prevent dirt redeposition by chelating hardness ions in water. Due to environmental reasons (eutrophication), their use in household detergents has been greatly reduced and replaced by zeolites, but they are still widely used in industrial cleaning.

4. Mining and mineral processing

  • Dispersants and inhibitors: Used as inhibitors for silicate minerals (such as quartz and feldspar) in mineral flotation processes, and also as dispersants for slurries to improve separation efficiency.

5. Ceramic industry

  • Water-reducing agents: Adding a small amount of SHMP to ceramic blanks and glazes can significantly reduce the water content of the slurry while maintaining good fluidity, facilitating spray drying and molding, and saving energy.

6. Textile Printing and Dyeing

  • Water softeners and dispersants: Soften water during bleaching, dyeing, and printing processes, prevent the precipitation of dyes and insoluble substances, and ensure uniform color.

7. Other Applications

  • Petroleum Industry: Used as a dispersant in drilling mud.

  • Coatings Industry: Used as a pigment dispersant.

  • Paper Industry: Used for pulp bleaching and as an auxiliary agent.

Safety Precautions


  • Safety: Safe within the prescribed dosage for food additives. However, excessive intake may interfere with the absorption of minerals such as calcium and magnesium. Industrial products may cause mild irritation to the eyes, skin, and respiratory tract.


  • Storage: Must be stored in a sealed container in a dry, cool, and well-ventilated place to prevent moisture absorption and clumping.
