Performance Characteristics
- White granular or powder with density of 0.35-0.90G/CM3 and melting point of 622°C
- Easily soluble in water with alkaline aqueous solution (PH 9.7 for 1% solution)
- Gradually hydrolyzes into phosphite in water with excellent metal ion complexation ability
- Forms soluble complexes with calcium, magnesium, iron and other metal ions
- Softens hard water and functions as an inorganic surfactant with properties similar to organic surfactants
Applications
- Synthetic detergent additive and soap agent to prevent bar soap grease precipitation and frosting
- Strong emulsifying effect on lubricating oil and fat
- Industrial water softener for tanning, pre-tanning, and dyeing processes
- Dispersant for paints, kaolin, magnesium oxide, calcium carbonate, and drilling mud
- Anti-oil agent in paper industry
Market Applications
Detergent Industry: Essential component in traditional detergents as wash aid, water softener and dispersant. Despite environmental trends, remains dominant in many developing countries.
Food Industry: Used as food additive (moisture retention agent, emulsifier, buffer) in processed meats, seafood, and dairy products with steady demand.
Water Treatment: Growing demand as water softener and corrosion inhibitor with increasing industrial water needs.
Ceramics & Paper Industry: Stable demand as dispersant and processing aid.
Market Trends
