- Detergents and Cleaning Products: STPP is a key ingredient in many industrial and household detergents. It acts as a builder, enhancing the cleaning efficiency of surfactants by softening water, preventing re - deposition of removed dirt, and providing alkalinity to assist cleaning.
- Food Industry: In the food industry, STPP is used as a food additive (E451) to improve the texture and quality of processed foods. It helps in retaining moisture, preventing spoilage, and enhancing the appearance of products such as canned meats, seafood, and processed cheeses.
- Water Treatment: STPP is used in water treatment processes to prevent scale formation and corrosion in pipes and boilers. It sequesters metal ions such as calcium and magnesium, thereby reducing water hardness.
- Textile Industry: In textile processing, STPP is used as a softening agent and a dye - fixing agent. It helps in improving the texture of fabrics and ensuring even dye distribution.
- Other Applications: STPP is also used in the production of ceramics, glass, and as a stabilizer in some industrial processes.
Product Description
WHAT IS IT?
STPP, or Sodium Tripolyphosphate (Na₅P₃O₁₀), is an inorganic compound composed of sodium ions (Na⁺) and tripolyphosphate ions (P₃O₁₀⁵⁻). It is a white crystalline powder or granular substance with a high solubility in water. Its molecular structure consists of three phosphate groups linked together, forming a chain-like structure that gives it unique properties.
