Monosodium phosphate (MSP), also known as anhydrous monobasic
sodium phosphate and sodium dihydrogen phosphate, is
an inorganic compound of sodium with dihydrogen phosphate (H2PO4)
anion. One of many sodium phosphates, it is a
common industrial chemical. It exists as an anhydrous salt, as well
as mono- and dihydrates.
Phosphates are often used in foods and in water treatment. The pH
of such formulations is generally adjusted by
mixtures of various sodium phosphates, such as this salt. The
sodium chloride equivalent value, or E-Value, is
0.49. It is soluble in 4.5 parts water.
It is added in animal feed, toothpaste, and evaporated milk. It is used as a thickening agent and emulsifier.
Monosodium phosphate is used to detect the presence of magnesium
ions in salts. Formation of a white precipitate
on the addition of ammonium chloride, ammonium hydroxide and
monosodium phosphate to an aqueous or dilute HCl
solution of the salt indicates presence of magnesium ions.
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.
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 8.08.6, 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. It is also used
as a dispersing agent to break down clay and other soil types.
It is used as an active ingredient in toothpastes as an
anti-staining and tartar prevention ingredient.
Artificial maple syrup, canned milk, cheese powders and dips, imitation cheese, whipped topping, packaged egg whites, roast beef, fish fillets, fruit jelly, frozen desserts, salad dressing, herring, breakfast cereal, ice cream, beer, and bottled beverages, among other foods, can contain sodium hexametaphosphate.
Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP), is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use.
In detergents
The majority of STPP is consumed as a component of commercial
detergents. It serves as a builder,” industrial jargon for a water
softener. In hard water (water that contains high concentrations of
Mg2+ and Ca2+), detergents are deactivated. Being a highly charged
chelating agent, TPP5 binds to dications tightly and prevents them
from interfering with the sulfonate detergent.
STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common in food production as E number E451. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. The Uni
