What is tripotassium phosphate?
Tripotassium phosphate is a salt that contains potassium ions, phosphorus and oxygen. It is usually found as a white powder. Tripotassium phosphate is used as an ingredient in some toothpastes and mouthwashes.
Tripotassium phosphate is a chemical compound with the formula KP2O7. It contains one mole each of potassium cations K+, phosphorous pentoxide P2O5-, and oxygen O2-. The formula can be written in two equivalent ways:K3P2O7 and K2P3O8. The second formula emphasizes that the central P atom has three bonds to oxygen atoms; it is tetrahedral.
Tripotassium phosphate has many uses in the food industry. It can be used to process cheese, to protect against spoiling or to add flavor or color to foods such as ice cream, soft drinks and baked goods. In addition to its use as a food additive, it can also be used in cosmetics and pharmaceuticals.
Tripotassium phosphate is sometimes referred to as TSPP or TPKP (tripolyphosphate). It is also known as E336 or E337 by the European Union’s food additive code system (E numbers).
What is tripotassium phosphate used for?
Tripotassium phosphate is a chemical compound that is used as an emulsifier and a stabilizer in food. It is also used in personal care products, such as soaps and shampoos.
Tripotassium phosphate is added to foods to help increase the shelf life of processed meats, such as hot dogs and sausages. It may also be added to some canned goods to prevent the formation of hydrogen gas bubbles. This can occur when the food is heated in the can, which causes air to be trapped inside the can. The bubbles can grow large enough to pop the lid off of the can when you open it.
Tripotassium phosphate is used in agriculture to improve soil structure and water retention. Tripotassium phosphate can also be used as a feed additive for livestock.
Tripotassium phosphate may be used in soaps and shampoos as an emulsifier or stabilizer. It also helps these products form a foam that makes them easier to rinse from your skin or hair.
How is tripotassium phosphate made?
Tripotassium phosphate is a salt of phosphoric acid and a common food additive. It is an inorganic compound with the formula KPO3. It occurs naturally as the mineral montebrasite.
Tripotassium phosphate is produced by heating potassium phosphate with phosphoric acid:
K2HPO4 + H3PO4 → KPO3 + H2O
It can also be produced by treating potassium aluminum sulfate with phosphorus pentoxide and water:
Al(SO4)3 + P2O5 + H2O → Al(H PO4)3 + SO4 (H2PO4)
Potassium aluminium sulfate is not prepared commercially, but rather it is made by reacting sodium hydrogen sulfate or ammonium chloride with aluminium metal at high temperatures.

What is the application of tripotassium phosphate?
As an alkaline phosphate, TKP is primarily used in food and other applications to adjust pH. Also, it can be used to replace trisodium phosphate when sodium reduction is desired.
Food
A multifunctional ingredient, tripotassium phosphate in food can be used as an acidity regulator, an emulsifying agent, a sequestrant, a potassium enhancer, a stabilizer and a low-sodium replacement.
Here are some food lists where you might have seen this ingredient:
- Meat
- Extruded & dry cereals
- Sauces
- Cheeses
- Whipped cream
A salt made from TKP can be used in the production of caramel color by assisting the caramelization process.
The TKP may also be used along with fatty acids in poultry processing to reduce some bacteria and yeasts.
Cereal
These ingredients can be found on Cheerios Cereals’ label. The purpose of TSP in cereal products is similar to that of trisodium phosphate:
- Make sure the acidity is right.
- TKP’s high alkalinity accelerates the cooking process in cooked breakfast cereals and makes them appear yellow or creamy.
- Due to its hygroscopicity, it can also be used as an anticaking agent to keep extruded cereal dry and free-flowing.
- Supplement potassium and phosphorus.
- As an alternative to trisodium phosphate.
Other uses
There are many uses for technical grade TKP, including fertilizers, washing and cleaning products, water softeners, and chemicals for water treatment.
Is tripotassium phosphate safe for use?
Tripotassium phosphate is a salt of potassium and phosphorus. It can be used as a fertilizer because it contains potassium and phosphorus, two nutrients that plants need to grow.
The Food and Drug Administration (FDA) has approved tripotassium phosphate for use as a food additive in canned fruits and vegetables, dehydrated potatoes, and frozen potatoes. The Food Chemicals Codex lists it as generally recognized as safe (GRAS).
Tripotassium phosphate is also used as an acidity regulator in canned fruits and vegetables, according to the Handbook of Food Chemistry, edited by Joseph DeRisi Jr. and John Giaimo Jr.
What does tripotassium phosphate do to your body?
Tripotassium phosphate is a mineral salt that your body uses to help keep fluid levels in balance, control acidity, and alkalinity, and maintain proper nerve function. It also helps your body absorb other nutrients.
Tripotassium phosphate has several roles in the body. It helps with digestion by activating certain enzymes that break down proteins and fats into smaller molecules that are easier for your body to digest. It also helps maintain the balance of fluids in your body, which affects blood pressure and other organ functions. Tripotassium phosphate also plays a role in keeping nerve cells healthy by helping transport potassium ions across cell membranes.
In addition to its roles as an electrolyte transporter and digestive enzyme activator, tripotassium phosphate has many other functions in the body:
Helps regulate blood pressure levels by controlling sodium levels in the blood
Helps maintain normal fluid balance by regulating water retention (diuretic) or urination (natriuretic)
Helps protect against muscle cramps by maintaining proper potassium levels
Tripotassium phosphate vs Trisodium phosphate
Tripotassium phosphate (TPK) and trisodium phosphate (TSP) are two different types of phosphates. Both are used for cleaning and sanitation purposes, but they have different chemical properties that make them better suited for certain situations.
Tripotassium phosphate (TPK)
Tripotassium phosphate is a soluble salt that is used for cleaning and sanitizing surfaces. It is non-abrasive and does not scratch surfaces. TPK is considered to be more environmentally friendly than TSP because it does not contain chlorine, which can deplete the ozone layer.
Trisodium phosphate (TSP)
Trisodium phosphate is an abrasive cleaning aid commonly used in household cleaners such as bleach and toilet bowl cleaners. It has many industrial uses as well, including as a defoaming agent in paper manufacturing, as a water treatment agent, and as an ingredient in carpet shampoo products.
What are the side effects of tripotassium phosphate?
Side effects of tripotassium phosphate include:
Nausea and vomiting. These can happen in people who take the drug for short periods of time, but they are more likely to happen if you take it for a long period of time or at high doses.
Low blood pressure (hypotension). This can happen in people who take high doses of this drug often.
Liver damage (hepatotoxicity). This can happen in people who take high doses over a long period of time, especially if they also have liver disease.
Kidney damage (nephrotoxicity). This can happen in people who have kidney disease or who take large amounts of this drug over a long period of time.
Is tripotassium phosphate bad for you?
Tripotassium phosphate is a mineral salt that is used in food as an additive. It is approved by the U.S. Food and Drug Administration (FDA) as a food additive, but it is not commonly consumed by itself. The European Union has set a maximum intake of 3 g/day for this substance. This means that it may be unsafe if consumed in large quantities or over an extended period of time.
