Monobasic Sodium Phosphate Monobasic

Mono Sodium Phosphate or Monosodium Phosphate (NaH2PO4, MSP), also known as anhydrous monobasic sodium phosphate or monosodium phosphate or sodium phosphate monobasic, is used as a laxative and, in combination with other sodium phosphates, as a pH buffer.

The pKa is 7.20. The sodium chloride equivalent value, or E-Value, is 0.49. It is soluble in 4.5 parts water. Monosodium phosphate is most commonly available as colorless crystals or a white powder. Sodium phosphate monobasic is insoluble in alcohol.

Dibasic Sodium Phosphate Dibasic

Di-Sodium Phosphate or Disodium Phosphate (Na2HPO4, DSP) or disodium phosphate or dibasic sodium phosphate or sodium phosphate dibasic is a sodium salt of phosphoric acid. It is a white powder that is highly hygroscopic and water soluble. Disodium phosphate is therefore used commercially as an anti-caking additive in powdered products. It is also known as Di sodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic. Sodium Phosphate Dibasic is commercially available in both the hydrated and anhydrous forms.

Other uses
Disodium phosphate DSP or Sodium Phosphate Dibasic can be used in cream of wheat to quicken cook time. Disodium phosphate DSP or Sodium Phosphate Dibasic is used in conjunction with TSP in many steam boiler applications. Sodium Phosphate Dibasic supplies the inventory of free phosphates to retard calcium scale formation.

Tribasic Sodium Phosphate Tribasic

Tri Sodium Phosphate or Trisodium Phosphate (Na3PO4, TSP), or trisodium phosphate or tribasic sodium phosphate or sodium phosphate tribasic is available at most hardware stores in white powder form, is a cleaning agent, stain remover and degreaser, commonly used to prepare surfaces for painting. It can also be called Tri sodium orthophosphate and has the chemical formula Na3PO4; however, it is generally found in hydrated forms. Sodium Phosphate Tribasic is a highly water-soluble ionic salt.

Trisodium phosphate can also be found as a food additive; it is used as an acidity regulator (buffering agent), emulsifier, thickening agent, nutrition enlargement agent and sequestrant (metal-chelating agent). In these uses, all sodium phosphates may be collectively referred to as sodium phosphate, or by E number E339. The same is true when sold as an enema, working as a laxative to treat constipation.

Cleaning products labeled as TSP Sodium Phosphate Tribasic may contain other ingredients as well, and may in fact be less than half TSP. So even "regular" TSP found at the hardware store may be half TSP and half "TSP substitute". Some large home improvement centers that sell paint no longer offer TSP.

Sodium Phosphate Tribasic TSP is commonly used after cleaning with mineral spirits in order to then clean up all the mineral spirits. TSP may be used with household chlorine bleach in the same solution, and this is particularly good for removing mildew from wood. The TSP alone can cause dark stains on redwood, and bleach prevents it. It is also used in various forms as a boiler treatment chemical for calcium precipitation, as well as regulating the caustic effects of DSP in coordinated phosphate chemistry. Sodium Phosphate Tribasic is also used to clean swimming pool polyester filter elements.

Arsenic: Not more than 3 mg/kg.
Fluoride: Not more than 0.005%.
Insoluble Substances: Not more than 0.1%.
Lead: Not more than 2 mg/kg.

Use
These items are only used as food additives. They are added to many foods as an emulsifier to prevent oil separation. Some examples are processed cheeses, processed meats, ready-made meals and tinned (canned) soups. They are also commonly added to powdered soups, boullions and gravy mixtures.
They can also be used as a leavening agent. Some examples of these foods include the batter coating on breaded fish or chicken, and commercially baked cakes.
Adding this item to food increases the shelf life of the food, maintaining the texture and appearance of the food.
