Tetrasodium pyrophosphate appears as odorless, white powder or granules. mp: 995°C. Density: 2.53 g/cm3. Solubility in water: 3.16 g/100 mL (cold water); 40.26 g/100 mL boiling water. Used as a wool de-fatting agent, in bleaching operations, as a food additive. The related substance tetrasodium pyrophosphate decahydrate (Na4P2O7*10H2O) occurs as colorless transparent crystals. Loses its water when heated to 93.8°C.

Sodium diphosphate is an inorganic sodium salt comprised of a diphosphate(4-) anion and four sodium(1+) cations. More commonly known as tetrasodium pyrophosphate, it finds much use in the food industry as an emulsifier and in dental hygiene as a calcium-chelating salt. It has a role as a food emulsifier and a chelator. It contains a diphosphate(4-).

Use
Tetrasodium pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing tetrasodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer.

In toothpaste and dental floss, tetrasodium pyrophosphate acts as a tartar control agent, serving to remove calcium and magnesium from saliva and thus preventing them from being deposited on teeth. Tetrasodium pyrophosphate is used in commercial dental rinses before brushing to aid in plaque reduction.

Tetrasodium pyrophosphate is sometimes used in household detergents to prevent similar deposition on clothing, but due to its phosphate content, it causes eutrophication of water, promoting algae growth.

Product description    
Potassium pyrophosphate, also known as tetra-sodium pyrophosphate, is made from the melting of di-potassium phosphate which causing it loss of one water molecule. At room temperature, it is a white crystalline powder or granules and has a strong moisture absorption capability in air and is easily soluble in water but insoluble in ethanol. Its aqueous solution is alkaline and has an effect on inhibition of food spoilage and fermentation. The pH of 1% aqueous solution is about 10.5. At about 25 ℃, the solubility of potassium pyrophosphate in 100g of water is 187g. It is hydrolyzed into potassium phosphate in acid or alkaline solution and can form a viscous-like slurry body when being mixed with water. It is mostly used in combination with other condensed phosphates, such as for the preparation of adhesive of ham and sausage in the ratio of 10% potassium pyrophosphate, 10% sodium pyrophosphate, 30% potassium polyphosphate, 30% sodium polyphosphate and 20% sodium metaphosphate. It is commonly used for preventing the generation of struvite in canned fish, preventing the discolouration of canned fruit, increasing the swelling degree of ice cream, the extracting amount of the raw materials of coffee as well as the yield of ham and sausage, enhancing the water holding capacity of fish, improving the taste and yield of noodles, and preventing the ageing of cheese. In order to strengthen and smooth the plating layer, the formulation of industrial production of the plating solution is often very complicated. It is previously often applied to cyanide as the complexing agent cyanide for preparing plating solution. However, because of the high toxicity of CN-, it does severe harm to the health of electroplating worker. Moreover, the discharge of CN-of sewage, waste gas also seriously contaminates the environment. So it is currently mainly applied of non-cyanide plating with the complexing agent replacing cyanide being potassium pyrophosphate.
potassium pyrophosphate has all the properties of other polymeric phosphate and is also similar to sodium pyrophosphate but with a larger solubility and being able to have chelation reaction with the metal ions in alkaline soil and heavy metal ion; It can also form complex with the Ca2 +, Mg2 + in hardening water thereby softening the hard water, improving washing ability as well as removing dirt. It can also form a protective film on the surface of metals such as iron, lead, zinc, and aluminium; the pyrophosphate ion (P2O74-) has a strong dispersing capability on the fine and dispersive solids, thus promoting the homogeneous mixing of fine, trace substances. High purity, low iron-type potassium pyrophosphate has a stable pH buffering capacity with the ability of long-term maintenance of pH value of the solution.

Chemical Properties
