Melting Point 622 Celsius Sodium Tripolyphosphate Powder STPP Used In Detergent Production
Product Description:
Sodium Tripolyphosphate (STPP), which is also referred to as pentasodium triphosphate or sodium triphosphate, has the chemical formula Na 5 P 3 O 10 and a molecular weight of 367.86. This compound typically appears as white granules or powder, with an apparent density ranging between 0.35 and 0.95 grams per cubic centimeter. It has a high melting point of 622°C.
STPP is highly soluble in water, where it produces an alkaline solution. Over time, it undergoes gradual hydrolysis in aqueous environments, resulting in the formation of orthophosphates. This characteristic makes it useful in various chemical processes and applications.
One of the notable features of Sodium Tripolyphosphate is its strong capability to chelate metal ions. It forms soluble complexes with metal ions such as calcium, magnesium, and iron. This property enables it to effectively soften hard water by binding these ions and preventing them from causing scale or reducing detergent efficiency.
Additionally, STPP functions as an inorganic surfactant, displaying several properties that are similar to those of organic surfactants. This makes it valuable in cleaning agents and other products where surfactant activity is required.
Features:
This substance effectively chelates hardness ions present in water, such as calcium (Ca²⁺) and magnesium (Mg²⁺). By doing so, it significantly reduces the hardness of the water, which helps to minimize the risk of inorganic salt deposition and scaling.
It plays a crucial role in dispersing and suspending solid particles and liquid droplets, thereby improving the overall stability and uniformity of the system. In formulations related to ceramics and building materials, it is commonly utilized as a water reducer, degummer, and dispersant. The primary objective is to make body slurries and glaze slurries more stable and fluid, facilitating easier flow and formation. This ultimately enhances process consistency and the quality of the final product.
The agent also emulsifies and peptizes oily and proteinaceous soils, which contributes to better detergency and improved cleaning efficiency.
Additionally, it helps maintain a weakly alkaline environment within the formulation. This pH buffering is beneficial for the removal of acidic soils and aids in stabilizing the overall performance of the formulation.

Applications:
In the field of ceramics and building materials, this substance is commonly used as an additive to enhance the stability of ceramic slurries. Additionally, it improves the forming performance during the production process, resulting in better-quality ceramic products.
Within the realm of detergents and soaps, it serves a crucial role as a builder in synthetic detergents. Moreover, it acts as a booster for soaps, significantly increasing their cleaning effectiveness and ensuring more efficient removal of dirt and stains.
For industrial water treatment applications, this compound is employed as an effective water softener. It helps prevent the formation of scale and contributes to the stabilization of process water and circulating water systems, thus enhancing the operational efficiency and longevity of industrial equipment.
In the leather and textile industries, it is utilized as a pre-tanning agent during leather processing, promoting uniform tanning results. Additionally, it functions as a dyeing auxiliary in textiles, which improves dye uptake and results in more vibrant and consistent coloration.
The compound also finds diverse applications in coatings, mineral processing, drilling, and papermaking. It acts as a dispersant in the preparation of suspensions involving paints, kaolin, magnesium oxide, and calcium carbonate. Furthermore, it serves as a dispersant in drilling fluids and as a grease-proofing agent within the paper manufacturing industry.
