Sodium Tripolyphosphate (STPP), also known as sodium pentaphosphate or triphosphate, is a widely used inorganic compound with the chemical formula Na₅P₃O₁₀. It is a white crystalline powder or granular substance that is highly soluble in water. STPP is primarily produced through the thermal condensation of sodium orthophosphate (Na₃PO₄) and is known for its multifunctional properties, including chelation, dispersion, emulsification, and buffering.
Key Properties
- Chemical Formula: Na₅P₃O₁₀
- Appearance: White crystalline powder or granules
- Solubility: Highly soluble in water
- pH: Alkaline in aqueous solution (typically around pH 9-10)

Applications
1. Detergent Industry
- Detergent Builder: STPP enhances cleaning efficiency by softening hard water, preventing dirt re-deposition, and improving detergent performance.
- Water Softener: Chelates calcium and magnesium ions in hard water, reducing insoluble soap scum and scale formation.
- Buffering Agent: Maintains alkaline pH essential for effective cleaning.
2. Food Industry
- Moisture Retention Agent: Enhances water-holding capacity in meat and seafood, improving texture and preventing drying.
- Quality Improver: Enhances tenderness and texture of meat products.
- pH Regulator: Maintains food product pH stability, extending shelf life.
- Metal Chelating Agent: Prevents undesirable reactions by chelating metal ions in food.
3. Water Treatment
- Scale Inhibitor: Prevents calcium and magnesium deposits in industrial water systems, boilers, and cooling towers.
- Corrosion Inhibitor: Forms protective film on metal surfaces, reducing corrosion.
4. Ceramic Industry
- Dispersant: Improves stability and fluidity of ceramic slurries, preventing particle aggregation.
- Grinding Aid: Enhances ball milling process efficiency.
- Deflocculant: Improves rheological properties of ceramic slurries for better shaping.
