Sodium Tripolyphosphate Tech Grade
Sodium tripolyphosphate (STPP) with chemical formula Na₅P₃O₁₀ is a significant condensed phosphate salt. This white crystalline powder or granules readily dissolves in water, producing an alkaline solution with powerful metal ion chelating ability, dispersing action, emulsifying properties, and pH buffering capacity.
Key Applications
Detergent Industry Builder
STPP serves as a multi-functional core component in synthetic detergents including laundry powders and dishwasher detergents, providing essential water softening, dispersion, emulsification, and alkalinity buffering capabilities.
- Water Softening: Chelates calcium and magnesium ions to prevent soap scum formation
- Dispersion & Emulsification: Suspends soil particles and prevents fabric redeposition
- Alkalinity Buffering: Maintains optimal alkaline environment for enhanced cleaning
Industrial Water Treatment
Used as corrosion and scale inhibitor in circulating cooling water systems and as drilling mud additive in oilfield operations to control rheology and fluid loss.
Food Industry Quality Improver (E451)
Food-grade STPP compliant with standards like GB 25566 functions as water retention agent, quality improver, pH regulator, and metal chelator.
- Meat Products: Enhances water retention, tenderness, and slicing properties in ham, sausages, and surimi
- Seafood Processing: Reduces thawing drip loss and maintains texture in frozen shrimp and crab
- Dairy & Beverages: Serves as stabilizer and emulsifier
Additional Industrial Applications
- Ceramics: Slurry dispersant reducing glaze and clay viscosity
- Textile: Water softener, dispersant, and scouring aid in dyeing and finishing
- Metal Surface Treatment: Used in derusting and coating pretreatment
- Paper Industry: Aid in pulp bleaching and dispersion processes
