Sodium Tripolyphosphate: Your Ultimate Solution for Water Treatment and Softening Needs

Product Description

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

Sodium tripolyphosphate is a pristine white crystalline powder known for its exceptional fluidity. The density varies slightly between its two forms; Type 1 boasts a density of 2.62g/cm³, while Type 2 has a density of 2.57g/cm³. With a high melting point of 622ºC, it effortlessly dissolves in water, creating an alkaline solution.

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

Sodium triphosphate (STPP or sodium tripolyphosphate) is a vital inorganic compound with the chemical formula Na5P3O10. This sodium salt is derived from the polyphosphate penta-anion, which itself is the conjugate base of triphosphoric acid. Produced on a significant scale, it serves as an essential ingredient in a multitude of domestic and industrial applications, especially
detergents.
However, environmental concerns have arisen regarding the compound's role in eutrophication, a process that can be exacerbated by its extensive use.

Product Application

1. STPP tech grade serves as a crucial additive in detergent synthesis, ceramics production, and soap synergist formulations.
2. Boasting a robust emulsifying capability, it effectively manages lubricants and fats, and fine-tunes the pH levels in buffer liquid soaps.
3. Acts as a superior water softener and buffering agent within the detergent industry.
4. Enhances quality, adjusts pH levels, serves as a water-retaining agent, and performs various other functions in the food industry.
5. Integral to the paper-making process.
6. Functions as a dispersing agent in oil drilling mud, ensuring efficient operations.
7. Widely used across ceramic, mining, and water treatment industries, among others.

Function in Detergent Industry:

STPP stands as an excellent auxiliary in the detergent industry, typically used in dosages ranging from 10% to 35%. Its primary roles within detergent systems include:

1. Softening hard water by reacting with metal ions such as Ca²⁺, Mg²⁺, and Fe³⁺, converting them from insoluble to soluble forms through the reaction: Na₅P₃O₁₀+ Ca²⁺ --->Na₃(CaP₃O₁₀)+2Na⁺
2. Enhances the emulsifying and dispersing power, increases the solubility of protein and dust commonly found on fabrics.
3. Acts as a buffering agent, maintaining the detergent solution's pH at 9 to 9.5, facilitating the removal of acidic dirt from fabrics.
4. Functions as an anti-caking agent for detergent powders. By absorbing moisture, STPP transforms into Hexahydrate, which remains dry and free-flowing, preventing caking.
