Chemate - Sodium Tripolyphosphate (STPP)
Sodium tripolyphosphate stpp, with the synonyms of pentasodium triphosphate, tripolyphosphate, is a type of amorphous water-soluble linear polyphosphate. For convenience, we usually call its abbreviation, STPP or stpp chemical. Sodium tripolyphosphate is a colourless salt, which exists both in the form of anhydrous and hexahydrate. With some special chemical properties, stpp can be widely used in detergents, water treatment, food processing industry and many other industrial fields. Inquiry us to tell us your applications and more about the requirements of stpp chemical, we will send you the sodium tripolyphosphate 94% msds and sodium tripolyphosphate TDS, as well as the quotation quickly.

Sodium Tripolyphosphate Uses
In Detergent
Sodium Tripolyphosphate Uses In Detergents
- Properties of chelating hard metal ions. The hard metal ions in the daily washing water will form insoluble metal salts with the active substances in the detergent, which not only increases the amount of detergent used, but also darkens the color of the washed clothes. Sodium tripolyphosphate uses in detergent can help solve this problem.
- Improve the role of peptization, emulsification and dispersion. STPP in detergent has a peptizing effect on proteins in human secretions, can promote the emulsification of fatty substances, and has a dispersing and suspending effect on solid particles such as sand and dust.
- Larger alkaline buffering effect. As an auxiliary agent for synthetic detergents, sodium tripolyphosphate stpp uses in detergent can maintain the PH value of the detergent at about 8.4, which can promote the removal of acidic dirt.
- Keep dry and prevent caking. Powdery synthetic detergents are hygroscopic. If stored in a place with high humidity, agglomeration phenomenon will occur, affecting the use. The hexahydrate formed after stpp chemical absorbs water has a dry characteristic. When there is a large amount of stpp powder in the detergent formula, it can prevent the caking phenomenon caused by moisture absorption and keep the dry granularity of the synthetic detergent.
In Food
Sodium Tripolyphosphate Uses In Food
- Used as preservative. Sodium tripolyphosphate uses in food can prevent or delay the oxidation of unsaturated fats, inhibit the growth of microorganisms, and play the role of antiseptic and bacteriostatic.
- The role of emulsification and dispersion. Sodium tripolyphosphate food grade has the effect of dispersing insoluble substances in water and forming a stable suspension to prevent the attachment and aggregation of the suspension.
- Used as food regulator. STPP food grade can effectively stabilize the liquid phase in the medium within a certain PH value range, which can make the food taste more delicious.
- Increase the water retention of food. STPP food grade powder has an enhanced effect on protein and globulin, so it can increase the water retention of meat products, improve the permeability of water, promote the softening of food and improve the quality of food, as well as maintain the excellent flavor of food.
In Industrial Fields
Sodium Tripolyphosphate Uses In Water Treatment
- Scale inhibitor. STPP chemical is often used as a scale inhibitor in cooling water treatment. Because the addition of a small amount of polyphosphate can effectively destroy the normal growth process of calcium carbonate and other crystals, thereby preventing the formation of calcium carbonate scale.
- In addition, sodium tripolyphosphate uses in water treatment can also be used as a water softener for industrial water, tanning agent, dyeing aid, used as a dispersant when preparing suspension in paint, kaolin, magnesium oxide, calcium carbonate and other industries, drilling mud dispersant and anti-oil stain agent in paper industry.
