Sodium Tripolyphosphate - The essential ingredient for superior performance!

Product Description

Premium Grade 94% Sodium Tripolyphosphate (STPP) for Versatile Applications in Detergents, Paints, and Water Treatment Solutions

Sodium tripolyphosphate (STPP) is presented as a fine white crystalline powder with excellent fluidity. Type 1 has a density of 2.62g/cm³, while Type 2 possesses a density of 2.57g/cm³. With a remarkable melting point of 622ºC, STPP is highly soluble in water, and its aqueous solution exhibits alkaline properties.

Solubility: Easily soluble in water, with a solubility ratio of 20g/100mL at 20ºC.

Sodium triphosphate, commonly known as STPP or sodium tripolyphosphate, is an essential inorganic compound with the chemical formula Na5P3O10. This sodium salt features the polyphosphate penta-anion, the conjugate base of triphosphoric acid. It is extensively manufactured and incorporated in a multitude of domestic and industrial products, prominently
Detergents.
Environmental concerns related to eutrophication have been associated with its extensive utilization across various applications.

Product Application

1. STPP tech grade serves as an essential additive in detergent synthesis, ceramics production, and as a soap synergist, enhancing the overall quality and performance.
2. It boasts a robust emulsifying property for lubricants and fats, effectively adjusting the pH value of buffer liquid soap.
3. In the detergent industry, it functions as a water softener and buffering agent, ensuring superior cleaning results.
4. In the food industry, it acts as a quality modifier, pH adjuster, water reserving agent, and serves various other functions to maintain product quality.
5. It is widely used in the paper-making industry for its effective properties.
6. As a dispersing agent in oil drilling mud, it significantly enhances the efficiency of the drilling process.
7. It finds applications in the ceramic, mining, and water treatment industries, among others, for its versatile properties.

Function in detergent industry:

STPP is a highly effective auxiliary in the detergent industry with a typical dosage of 10~35%. Its functions in the detergent system include:

1. Softening hard water by reacting with metal ions, such as Ca²⁺, Mg²⁺, Fe³⁺and others, converting them from insoluble to soluble forms, which enhances cleaning power. Na₅P₃O₁₀+Ca²⁺ --->Na₃(CaP₃O₁₀)+2Na⁺
2. Enhancing emulsifying and dispersing capabilities, it increases the solubility of proteins and dust commonly found in fabrics from daily use.
3. As a buffering agent, it maintains the pH value of the detergent solution at a level of 9~9.5, facilitating the removal of acid-based dirt from fabrics.
4. It acts as an anti-caking agent for detergent powder, absorbing moisture and forming Hexahydrate, which is dry and free-flowing, preventing caking in exposed air.
