96% Na5P3O10 STPP Use In Detergent CAS 7758-29-4 Sodium Tripolyphosphate

Product Description:

Sodium Tripolyphosphate (STPP), also known by other names such as pentasodium triphosphate or sodium triphosphate, is a chemical compound with the formula Na₅P₃O₁₀. It has a molecular weight of 367.86 and is commonly found in the form of white granules or powder. The substance has an apparent density ranging between 0.35 and 0.95 g/cm³ and a high melting point of 622°C.

STPP is highly soluble in water, where it creates an alkaline solution. Over time, it undergoes hydrolysis in water, breaking down gradually into orthophosphates. This characteristic contributes to its various applications in different industries.

One notable property of Sodium Tripolyphosphate is its strong metal ion chelating ability. It can form soluble complexes with metal ions such as calcium, magnesium, and iron. Through this mechanism, STPP effectively softens hard water by binding these ions and preventing their interference in various processes.

Additionally, as an inorganic surfactant, STPP shares some functional similarities with organic surfactants. This allows it to perform roles that aid in cleaning and emulsification in numerous products and formulations.

Features:

This compound effectively chelates hardness ions found in water, such as calcium (Ca ²⁺ ) and magnesium (Mg ²⁺ ) ions. By binding these ions, it significantly reduces the hardness of water. This reduction helps minimize the formation of inorganic salt deposits and scaling, which can otherwise lead to operational issues in various systems.

It plays an important role in dispersing and suspending solid particles as well as liquid droplets. This action improves the stability and uniformity of the system. In the fields of ceramics and building material formulations, it is widely used as a water reducer, degummer, and dispersant. Its main purpose is to stabilize body slurries and glaze slurries, making them easier to flow and form. This ultimately enhances the consistency of the manufacturing process and the quality of the final products.

The compound also emulsifies and peptizes oily and proteinaceous soils. These processes boost the detergency and cleaning efficiency of formulations, making it highly effective in removing stubborn organic residues.

Additionally, it helps maintain a weakly alkaline environment within the formulation. This pH buffering is advantageous for removing acidic soils and contributes to the overall stability and performance of the product.

Applications:

In the field of ceramics and building materials, this additive plays a crucial role by enhancing the stability of ceramic slurries. It also improves the forming performance during the production process, leading to better-quality ceramic products.

When it comes to detergents and soaps, the substance functions as a builder in synthetic detergents. Additionally, it acts as a soap booster, which significantly enhances the overall cleaning effectiveness of the products.

In industrial water treatment, this additive is widely used as a water softener. It helps prevent the formation of scale while improving the stability of both process water and circulating water systems in various industrial applications.

Within the leather and textile industries, it serves as a pre-tanning agent that promotes uniform tanning in leather production. Moreover, it acts as a dyeing auxiliary in textile manufacturing, improving dye uptake and resulting in more vibrant colors.

Finally, in coatings, mineral processing, drilling, and papermaking, the additive functions as an effective dispersant. It is utilized in preparing suspensions for paints, kaolin, magnesium oxide, and calcium carbonate. It also serves as a dispersant in drilling fluids and plays a role as a grease-proofing agent in the paper industry.
