CAS Number 7758-29-4 White Powder STPP Sodium Tripolyphosphate Ideal For Additive Of Detergents And Soaps
Sodium Tripolyphosphate (STPP), also referred to as pentasodium triphosphate or sodium triphosphate, has the chemical formula Na₅P₃O₁₀ and a molecular weight of 367.86. It commonly appears in the form of white granules or powder. The compound has an apparent density ranging from 0.35 to 0.95 grams per cubic centimeter and melts at a temperature of 622°C.
This substance is highly soluble in water, where it generates an alkaline solution. Over time, it undergoes hydrolysis in aqueous environments, leading to the formation of orthophosphates. This gradual breakdown contributes to its various applications in water treatment and other industries.
One of the notable features of Sodium Tripolyphosphate is its strong ability to chelate metal ions. It forms soluble complexes with ions such as calcium, magnesium, and iron, which helps in softening hard water. Due to this property, it is widely used in detergents and cleaning agents to enhance their effectiveness.
Additionally, STPP acts as an inorganic surfactant and shares some characteristics with organic surfactants. This allows it to perform certain surface-active functions, making it valuable in diverse industrial processes.
Chelation and Water Softening: This process effectively binds hardness ions in water, such as calcium (Ca²⁺) and magnesium (Mg²⁺), which significantly lowers water hardness. By doing so, it helps to reduce the risk of inorganic salt deposits and scaling, thus protecting pipes and equipment from damage.
Dispersion and Suspension: It plays a crucial role in dispersing and suspending solid particles and liquid droplets, which enhances the stability and uniformity of the system. In the context of ceramic and building material formulations, this function is commonly utilized as a water reducer, degummer, and dispersant. The main objective is to stabilize body slurries and glaze slurries, making them flow more easily and form better. This leads to improved process consistency and higher product quality.
Emulsification and Peptization: This action involves emulsifying and peptizing oily and protein-based soils, thereby improving the detergency and overall cleaning efficiency. It ensures that stubborn soils are broken down effectively for easier removal during cleaning processes.
pH Buffering: Maintaining a weakly alkaline environment within the formulation is another key function. This pH buffering is advantageous for removing acidic soils and contributes to the stabilization of the formulation’s performance, ensuring consistent results.

In the field of ceramics and building materials, this additive plays a crucial role by enhancing the stability of slurry mixtures and improving the forming performance during ceramic production. Its use ensures better quality and consistency in ceramic products.
When it comes to detergents and soaps, the additive functions as an effective builder in synthetic detergents and acts as a soap booster. This dual role significantly enhances the overall cleaning power, making detergents more efficient in removing dirt and stains.
Industrial water treatment benefits from this additive as well, where it is utilized as a water softener. It helps in preventing scale formation and contributes to maintaining the stability of process water and circulating water systems, thereby optimizing industrial operations.
In the leather and textile industries, the additive serves as a pre-tanning agent during leather manufacturing and as a dyeing auxiliary in textiles. These applications lead to more uniform tanning and improved dye uptake, resulting in higher quality finished products.
Additionally, this additive finds diverse uses in coatings, mineral processing, drilling, and papermaking. It acts as a dispersant to prepare suspensions in paints, kaolin, magnesium oxide, and calcium carbonate. Furthermore, it functions as a dispersant in drilling fluids and serves as a grease-proofing agent within the paper industry.
Package:
STPP (Sodium Tripolyphosphate) is typically packaged in moisture-proof, multi-layer kraft paper bags or plastic woven bags with a polyethylene inner lining to ensure product stability and prevent contamination.The standard packaging size is usually 25 kg per bag, but customized packaging options can be arranged based on customer requirements.
