Sodium Tripolyphosphate (STPP), also known as Pentasodium triphosphate or Sodium tripolyphosphate pentabasic, is an inorganic compound belonging to the phosphate family. It exists as a white powder that is highly soluble in water and forms an alkaline solution. STPP has two crystalline forms, namely Na5P3O10-I (α-form, high-temperature stable) and Na5P3O10-II (β-form, low-temperature stable), which share similar chemical properties but differ in thermal stability, solubility, hydration heat, and hygroscopicity.

1. Food Industry: STPP is used as a chelating agent, buffer, and flavor enhancer in food processing. It helps to maintain the quality and stability of food products by binding metal ions and adjusting the pH levels.
2. Detergent Industry: Due to its excellent water-softening ability and dispersing properties, STPP is widely used in detergents and cleaning products to enhance cleaning efficiency and prevent the formation of soap scum.
3. Water Treatment: In water treatment applications, STPP serves as a scale inhibitor and corrosion inhibitor, preventing the deposition of minerals and the corrosion of equipment.

1. Chelating Agent: STPP has a strong ability to chelate metal ions such as calcium, magnesium, and iron, forming soluble complexes that can soften hard water and improve the performance of detergents and cleaning products.
2. pH Adjuster: As a buffer, STPP helps to stabilize the pH levels in various applications, ensuring optimal conditions for chemical reactions and process stability.
3. Dispersing Agent: Its dispersing properties make STPP effective in preventing the agglomeration of particles, ensuring a uniform distribution and enhancing the overall effectiveness of the product.
