Product Description

High-Quality 94% Sodium Tripolyphosphate (STPP) - Ideal for Detergents, Paints, and Water Treatment Solutions

Sodium tripolyphosphate is a fine white powder crystal known for its excellent fluidity. It has a density of 2.62g/cm³ for type 1 and 2.57g/cm³ for type 2, with a melting point of 622ºC. This compound is easily soluble in water and forms an alkaline aqueous solution.

Solubility: Highly soluble in water, 20g/100mL at 20ºC

Sodium triphosphate, commonly known as STPP or sodium tripolyphosphate, is an inorganic compound with the formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, the conjugate base of triphosphoric acid. It is manufactured on a large scale and is a crucial component in many domestic and industrial products, particularly
detergents.
Environmental concerns related to eutrophication are often attributed to its extensive use.

Sodium Tripolyphosphate Application

Product Application

1. STPP tech grade serves as an indispensable additive in the synthesis of detergents, the production of ceramics, and as a soap synergist.
2. It boasts a potent emulsifying property for lubricants and fats, effectively adjusting the pH value of buffer liquid soaps.
3. Acts as a water softener and buffering agent within the detergent industry, ensuring optimal performance.
4. Functions as a quality modifier, pH adjuster, water reserving agent, and more within the food industry, enhancing overall product quality.
5. Integral to the paper-making process, improving efficiency and quality.
6. Serves as a dispersing agent in oil drilling mud, ensuring smooth and efficient operations.
7. Widely used in ceramic, mining, water treatment industries, and more, showcasing its versatility.

Function in Detergent Industry:

STPP stands out as an excellent auxiliary in the detergent industry, with a typical usage rate of about 10~35%. Its functions in detergent systems are as follows:

1. Softens hard water by reacting with metal ions such as Ca²⁺, Mg²⁺, Fe³⁺and others, converting them from insoluble to soluble forms. Na₅P₃O₁₀+Ca²⁺ --->Na₃(CaP₃O₁₀)+2Na⁺
2. Enhances the emulsifying and dispersing power, increasing the solubility of proteins and dust commonly found in daily fabrics.
3. Acts as a buffering agent, maintaining the pH value of the detergent solution at a level of 9~9.5, thereby facilitating the removal of acidic dirt from fabrics.
4. Functions as an anti-caking agent for detergent powder. STPP absorbs moisture and transforms into Hexahydrate, remaining dry and free-flowing, thus preventing caking.
