Sodium Tripolyphosphate STPP

Sodium Tripolyphosphate (STPP), with formula Na5P3O10, is an inorganic, white crystalline powder. It enhances cleaning power by chelating hard water ions (calcium, magnesium) and suspending soil, preventing redeposition. STPP is commonly found in granular or powder form. It is used in cleaning products, ceramics and food processing. It improves cleaning performance, acts as an emulsifier and is often used in industrial, textile and oil drilling applications.

Applications of Sodium Tripolyphosphate (STPP):

Detergents & Cleaning Agents (Primary Use): STPP acts as a "builder," meaning it softens water by chelating calcium and magnesium ions, improving the efficiency of surfactants. It is used in laundry detergents, automatic dishwashing detergents and industrial cleaners to remove dirt and prevent soil redeposition.

Food Industry (Food Grade): STPP is used to retain moisture and improve texture in seafood (fish, shrimp), processed meats and poultry. It serves as a preservative to maintain freshness and color and as an emulsifier in dairy products. It is also used in pet food to maintain moisture.

Water Treatment: It is used to prevent scale formation and corrosion in industrial water systems, such as cooling towers and boilers.

Industrial Applications:

• Ceramics: STPP acts as a deflocculant & viscosity reducer in glazes, enhancing the finish of products.

• Leather Tanning: It is used as a masking agent and a synthetic tanning agent (syntan) to improve leather quality.

• Textiles & Paper: It is used in paper manufacturing and as a dispersing agent in textile dyeing.

• Other: It is used in paint & pigments.
