STPP is an excellent detergent that is widely used in the production of detergents. As a chelating agent, this substance prevents the production of insoluble salts during washing and increases the cleaning properties of the detergent. This combination prevents the absorption of moisture by detergents and in other words maintains the uniform texture of these compounds with the anti-caking effect, and by creating an alkaline buffer and maintaining the pH of the solution at around 9.4, it causes acidic pollution to be removed quickly.Sodium tripolyphosphate is a bactericide and its use in the combination of dishwashing tablets, soaps and laundry powders can help to disinfect dishes and clothes. This substance is also used as a preservative in chicken, meat, seafood

What is the use of sodium tripolyphosphate

STPP is a solid mineral compound that is used in a wide variety of products, including household detergents, food, construction materials, and animal feed. This material is used in the combination of powder, liquid, gel, washing tablets, and by reducing the hardness of the water, it makes the surfactants work effectively

All washing powders today contain 30-50% STPP. This compound is used to reduce water hardness by forming a soluble complex with Ca and Mg ions.From the point of view of allotropy, this material is produced in three forms, which include the following

Phase one or thermodynamic phase that is produced at high temperature

Phase two or kinetic phase which is produced at low temperature and is unstable at high temperatures

In crystalline form with six water molecules, which is the result of the combination of the mentioned two phases with water

The price of buying and selling sodium tripolyphosphate

This chemical compound is bought and sold in the form of soft powder with a mesh between 100 and 200 and granules in the market, and its toxicity is very small. This material is produced in two edible and industrial grades. Edible grade is used as a preservative in juice production industries, canning industries, dairy industries and soybean products, etc. STPP industrial grade is used in detergent and cleaner industries, tile and ceramic production industry, etc. STPP is stable at ambient temperature, but it turns into pyrophosphate and phosphate at 100 degrees Celsius.The total consumption of this material for the production of detergents in Western Europe is estimated at approximately 300,000 tons, and it is estimated that 90-95% of this material is used in Europe

Environmental hazards of sodium tripolyphosphate

This substance enters the environment as a part of domestic sewage and sewage treatment plants, and since it is an inorganic substance, its biodegradability has not been studied. However, it appears that sodium tripolyphosphate is hydrolyzed to orthophosphate and absorbed by algae or microorganisms, thus entering the natural phosphorus cycle

Because it is highly soluble in water, STPP is not significantly removed by wastewater treatment. Due to its physical and chemical properties, STPP is not distributed in the atmosphere and its work does not end with sedimentation in the soil because it is very soluble in water and does not easily enter sewage sludge and soil.Conditions of storage and sale of sodium tripolyphosphate

This chemical compound is bought and sold in 25 kg woven paper or plastic bags. STPP should be stored in a well-ventilated and dry warehouse, kept away from water, moisture and sunlight during transportation, and handled carefully to avoid damage to the plastic bags. In addition, it should be kept away from toxic substances

The price of tripolyphosphate

Tripolyphosphate has a similar appearance to white salt crystals and is often priced and sold in the thermodynamic and synthetic form. This material is produced through the electrothermal reaction of phosphoric acid and the wet process method and is widely marketed. This material is also a disinfectant and kills bacteria, which is why it is often used in the preparation of soaps, washing powder, and dishwasher detergents.In addition, it is often used as a preservative in food and processed foods. In general, it can be said that tripolyphosphate is known as a material with various applications in various industries.
