Sodium hexametaphosphate (or SHMP) is a white powder, white fine powder, white granular or colorless piece.
Sodium Hexametaphosphate, also referred to as E452i, SHMP, Graham's Salt, Sodium Polymetaphosphate, or just Hex.
It is an additive in a variety of foods and beverages and commonly used for thickening, emulsifying, and adding texture.

Sodium Hexametaphosphate (SHMP) Plates are white or clear, odorless plates.
This product is cleared to decrease the amount of cooked-out juices in poultry, canned hams, pork shoulder picnics and loins, canned hams and pork shoulder picnics, chopped ham and bacon as follows: 5.0% phosphate in pickle at 10% pump level; 0.5% phosphate in product (only clear solutions may be injected into product).[9 CFR 381.147 and 318.7]

Sodium hexametaphosphate is an inorganic polyphosphate salt commonly used as a corrosion inhibitor, emulsifying agent and as a tooth whitening agent in dentifrice formulations.


SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i.
Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0–8.6, which produces a number of SHMP products used for water softening and detergents.

A significant use for sodium hexametaphosphate is as a deflocculant in the production of clay-based ceramic particles.

SHMP- Sodium Hexametaphosphate is also used as a dispersing agent to break down clay and other soil types for soil texture assessment.
SHMP- Sodium Hexametaphosphate is used as an active ingredient in toothpastes as an anti-staining and tartar prevention ingredient.

Sodium hexametaphosphate (SHMP) generally performs very well at close-to-neutral pH ranges, while tetrasodium pyrophosphate (TSPP) and sodium tripolyphosphate (STPP) work best under alkaline conditions.
Monosodium phosphate (MSP) is often used together with SHMP for more acidic pH environments.
The so-called threshold effect refers to the ability of some phosphate compounds to inhibit the formation of carbonate or sulfate scales well below the amount that would be required for a stoichiometric 1:1 combination with the metal ions.

This apparently results by the phosphate interfering with early crystal growth.
In the case of SHMP, only 2-4 ppm is all that is required to inhibit scale formation in water with relatively high calcium levels.
