Sodium hexametaphosphate (SHMP) is a salt of composition Na6[(PO3)6]. Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates (empirical formula: NaPO3), of which the hexamer is one, and is usually the compound referred to by this name. Such a mixture is more correctly termed sodium polymetaphosphate. They are white solids that dissolve in water.

Sodium Hexametaphosphate (SHMP) is an inorganic compound of sodium salt and hexaphosphoric acid. It is sometimes called Sodium Polymetaphosphate, which stands for a more correct chemical term, but is rarely used among manufacturers, suppliers, and distributors. In general, all applications of SHMP fall into two grades: food grade and industrial/tech grade.Sodium Hexametaphosphate is used in a variety of food products and is labeled as E452i, although it is generally recognized as safe when applied in foods. Due to its characteristics of sequestrant, thickener, emulsifier, and texturizer, SHMP can be found in many daily products that we consume.

Sodium hexametaphosphate, also known as its abbreviation SHMP, a polyphosphate commonly used in dairy products, sausage, seafood, meat processing, toothpaste, and also in water treatment. The European food additive number for it is E452i. Generally, its purpose in food is as a texturizer, sequestrant, thickener, and emulsifier. 

First of all, you may be wondering two things...what is sodium hexametaphosphate? And just what is a dispersing agent?To start, sodium hexametaphosphate (SHMP) is a hexamer of composition (NaPO3)6.Sodium hexametaphosphate of commerce is typically a mixture of polymeric metaphosphates, of which the hexamer is one, and is usually the compound referred to by this name. It is more correctly termed sodium polymetaphosphate. It is prepared by melting monosodium orthophosphate, followed by rapid cooling.

Also known as Calgon, sodium hexametaphosphate is a chemical compound that consists of a mix of polymeric metaphosphates. It is a hexamer that contains repeated \[(NaPO_{3})\]units. This means that it is a polymer that has six molecular compositions of a monomer. This compound is soluble in water and has a circulation of multiple polyphosphate chain lengths. This compound forms as a result of a thermal procedure that is formed from monosodium orthophosphate. 

Sodium hexametaphosphate is a kind of sodium metaphosphate polymers. It is also known as "polyvinylidene sodium," "sodium multiple metaphosphate", "sodium metaphosphate vitreous body", and "Graham salt". It is a colorless transparent glass-like solid or white powder with greater solubility but low dissolving rate in water. Its aqueous solution exhibits acidic property. Its complex of divalent metal ion is relatively more stable than the complexes of mono-valent metal ion. It can easily be hydrolyzed to orthophosphate in warm water, acid or alkali solution. Hexametaphosphate has a relative strong hygroscopicity with being sticky after absorbing moisture. For certain metal ions (e.g., calcium, magnesium, etc.), it has the ability to form soluble complexes, and thus being able to being used for demineralizing water. It can also from precipitate with lead and silver ions with precipitate being re-dissolved in excess amount of sodium hexametaphosphate solution to form a complex salt. Its barium salt can also form complexes with the sodium hexametaphosphate. It can be used as a kind of highly efficient water softener of power stations, rolling stock boiler water; as detergent additive, as corrosion-controlling or anti-corrosion agents; as cement hardening accelerator; as streptomycin purification agent, and the cleaning agent of textile industry and dyeing industry. It can also be used as a kind of sedative drug, preservative, stabilizer, and fruit juice precipitant in food industry. In the oil industry, it is used for control of drilling pipe rust and adjusting the viscosity of oil drilling mud. It also has applications in fabric dyeing, tanning, paper, color film, soil analysis, radiation chemistry and analytical chemistry and other departments. Our GB2760-1996 provisions that hexametaphosphate is allowable food additives (water retention agent) for being used for canned food, fruit juice drinks, dairy products, soy products; it can also be used as a dye dispersant, and water treatment agent.

Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are all sodium polyphosphates made of repeating units of NaPO3. Sodium Metaphosphate generally refers to a long chain of NaPO3 units that is not soluble in water, which is why it is sometimes called insoluble metaphosphate. Sodium Trimetaphosphate has three NaPO3 units, and Sodium Hexametaphosphate has six NaPO3 units. Both the Trimetaphosphate and the Hexametaphosphate are soluble in water. In cosmetics and personal care products, Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are used in the formulation of makeup foundations, mascara, bath products, and moisturizing and skin care products.

Sodium Hexametaphosphate(SHMP), a polymer of sodium metaphosphate is usually white power crystal, colorless transparent glass flake or block solid in appearance. SHMP is soluble in water but insoluble in organic solvents. With strong hygroscopic property, it can gradually absorbs water and forms a gooey substance in the air. For that, it is very easy to delirium in air, please keep it sealed. The solubility in water is higher, but the dissolution rate is slower. The aqueous solution is acidic and it is easily to hydrolyze into phosphite. For some metal ions, sodium hexametaphosphate 68% has the ability to form soluble complex, so it is usually used to soften water. In addition, it can also form complex compound with lead, silver, barium salt, etc… With so many unique physical and chemical properties, SHMP has a wide range of uses in food processing industry and other various industrial fields.

The merchandise subject to this order is sodium hexametaphosphate. Sodium hexametaphosphate is a water-soluble polyphosphate glass that consists of a distribution of polyphosphate chain lengths. It is a collection of sodium polyphosphate polymers built on repeating NaPO3 units. Sodium hexametaphosphate has a P2O5 content from 60 to 71 percent. Alternate names for sodium hexametaphosphate include the following: Calgon; Calgon S; Glassy Sodium Phosphate; Sodium Polyphosphate, Glassy; Metaphosphoric Acid; Sodium Salt; Sodium Acid Metaphosphate; Graham’s Salt; Sodium Hex; Polyphosphoric Acid, Sodium Salt; Glass H; Hexaphos; Sodaphos; Vitrafos; and BAC-N-FOS. Sodium hexametaphosphate is typically sold as a white powder or granule (crushed) and may also be sold in the form of sheets (glass) or as a liquid solution. It is imported under heading 2835.39.5000, HTSUS. It may also be imported as a blend or mixture under heading 3824.90.3900, HTSUS. The American Chemical Society, Chemical Abstract Service (“CAS”) has assigned the name “Polyphosphoric Acid, Sodium Salt” to sodium hexametaphosphate. The CAS registry number is 68915-31-1. However, sodium hexametaphosphate is commonly identified by CAS No. 10124-56-8 in the market. For purposes of this order, the narrative description is dispositive, not the tariff heading, CAS registry number or CAS name.

Sodium hexametaphosphate is a water softener, commercially known as Calgon. The term Calgon is associated with calcium, which specifically indicates the elimination of calcium ions from water. The presence of calcium and certain cations in water enhances the water hardness, which in turn is reduced by applying powdered sodium hexametaphosphate, forming complexes with calcium and other ions. In 1963, the German chemists Erich Thilo and Ulrich Schülke discovered it by preparing sodium hexametaphosphate by heating anhydrous sodium trimetaphosphate.

The key difference between sodium hexametaphosphate and sodium polyphosphate is that sodium hexametaphosphate is a specific six-chain length form of sodium metaphosphate, whereas sodium polyphosphate is an umbrella term used to name all the sodium phosphate units with four or more phosphate units.The terms sodium hexametaphosphate and sodium polyphosphate refer to substances derived from sodium phosphate salts. These are usually large molecules with complicated chemical formulas.
