Product introduction：

Sodium tripolyphosphate, white powder crystal, good fluidity, relative molecular weight 367.86, melting point 622 ℃, easily soluble in water, its aqueous solution is alkaline. It is often used as a moisturizer, quality improver, pH regulator, metal chelating agent, etc. in food. The aqueous solution of sodium tripolyphosphate is weakly alkaline (the pH value of 1% aqueous solution is about 9.7), and it forms a suspension (similar to an emulsion) in water with a pH value ranging from 4.3 to 14, that is dispersed. Sodium tripolyphosphate can also dissolve liquid and solid particles in liquid (such as water) media better, making the solution completely transparent in appearance, just like a true solution, which is solubilization. Because sodium tripolyphosphate has the above-mentioned unique properties, it has become an important ideal raw material in washing powder.

What is application of Sodium Tripolyphosphate?

Sodium tripolyphosphate has the functions of chelating, suspending, dispersing, peptizing, emulsifying, pH buffering, etc., and can be used as the main auxiliary agent of synthetic detergent, industrial water softener, pretanning agent for tanning, dyeing auxiliary agent, organic synthesis catalyst , pharmaceutical industry dispersants and food additives, etc.

How is Sodium Tripolyphosphate used food industry?

1. In the food industry, it is mainly used as a quality improver for canned food, dairy products, fruit juice drinks and soy milk; as a water-retaining agent and tenderizer for meat products such as ham sausage and luncheon meat; it can play a role in water retention in the processing of aquatic products And tenderization, swelling and bleaching; in canned broad beans, it can soften skin beans; it can also be used as water softener, chelating agent, PH regulator and thickener, and in the beer industry.

3. How is Sodium Tripolyphosphate usd in detergent builder?

Sodium tripolyphosphate is a detergent builder with excellent performance, and it is also the most used component in the detergent production process. During the washing process, heavy metal ions in water can combine with detergent molecules to form insoluble metal salts, which will reduce the washing ability or even completely lose its effect. It has the functions of degumming, emulsifying and dispersing dirt. At the same time, it also has the effect of preventing the detergent from caking. It also has a large alkaline buffering effect, keeping the pH value of the washing solution at about 9.4, which is beneficial to the removal of acidic dirt.

How is Sodium Tripolyphosphate usd in industry?

Industrial water softener, leather pretanning agent, dyeing auxiliaries, oil well dredging control agent, oil pollution preventive agent for paper making, effective dispersant for suspension treatment of paint, kaolin, magnesium oxide, calcium carbonate, etc., ceramic industry for ceramics Debonding agent, water reducing agent. 

What is the benefits of Sodium Tripolyphosphate?

There are many reasons to add Sodium Tripolyphosphate to food, washing powder, or other products. It can:

Quality improver. As a quality improver, it can improve the complexed metal ions, pH value, and ionic strength of food, thereby improving the binding force and water holding capacity of food. Can be used in different food products such as dairy products, fish products, poultry products, ice cream and instant noodles

Water remaining agent. It can be used as a water retention agent and tenderizer for meat products such as ham sausage and luncheon meat; it can play the role of water retention, tenderization, expansion and bleaching in the processing of aquatic products

Softener. It is used in the production of canned broad beans to soften the bean skin. Many fruits and vegetables have tough outer skins. As the fruits and vegetables mature, the outer skins become tougher. Adding polyphosphate to the blanching or soaking water for fruit and vegetable processing can complex calcium, thereby reducing the toughness of the outer skins.

Detergent. Sodium tripolyphosphate is used in detergents as a builder, soap builder and to prevent crystallization and blooming of bar soaps.

Industrial applications. It is used as a high-efficiency water softener for cooling water treatment in power stations, rolling stock, boilers and chemical fertilizer plants. Industrial water softener, leather pretanning agent, dyeing auxiliaries, oil well dredging control agent, oil pollution preventive agent for paper making, effective dispersant for suspension treatment of paint, kaolin, magnesium oxide, calcium carbonate, etc., ceramic industry for ceramics Debonding agent, water reducing agent.
