Physical and Chemical Properties
  • Highly soluble in water (14 g/100 mL at 20°C, 30 g/100 mL at 60°C)
  • Insoluble in organic solvents (ethanol, etc.)
  • 1% aqueous solution pH: 9.5-10.5 (alkaline)
  • Decomposes at 622°C into sodium pyrophosphate and sodium metaphosphate
  • Strong hygroscopicity - easily absorbs moisture from air
  • Excellent chelating ability for metal ions (Ca, Mg, Fe)
  • Forms stable soluble complexes in water treatment applications

Market Applications and Development
Key Industry Applications
  • Detergent Industry: Traditional builder agent (phasing out in some regions)
  • Industry: Water retention and texture improvement (E451 additive)
  • Water Treatment: Scale and corrosion prevention in industrial systems
Environmental Considerations
Due to potential eutrophication concerns, many regions are implementing phosphorus restrictions. However, sodium tripolyphosphate remains essential in specific industrial applications where alternatives are less effective.
Industrial application of Sodium Tripolyphosphate
