Sodium Tripolyphosphate (STPP) – Industrial & Food Grade
Sodium Tripolyphosphate (STPP) is a versatile inorganic compound widely used in both industrial and food sectors. As a white, crystalline powder or granule, STPP offers excellent chelating, dispersing, and emulsifying properties.
Industrial Grade STPP is commonly applied in:
Detergent formulations as a water softener and anti-redeposition agent
Ceramic, textile, and leather processing as a dispersant and deflocculant
Oil drilling and water treatment as a scale inhibitor and dispersing agent
Metal surface treatment to improve cleaning efficiency
Food Grade STPP is primarily used as a food additive (E451), serving as:
A preservative and moisture-retention agent in seafood, meat, poultry, and processed foods
A stabilizer and emulsifier in dairy products and beverages
A pH buffer and texturizer in noodles and other starch-based products
With high solubility and stable chemical performance, STPP ensures consistent results in a wide range of applications. Our company supplies both industrial and food grade STPP with customizable specifications and packaging options.
