1. Product Overview & Specifications

Sodium Tripolyphosphate (STPP), CAS 7758-29-4, is a white crystalline powder with the chemical formula Na₅P₃O₁₀ and molecular weight 367.86. It is highly soluble in water (20 g/100 mL at 20°C) and exhibits alkaline properties (pH 9.0–10.0).

2. Key Applications

2.1 Detergent Manufacturing

• Enhances surfactant efficiency by softening water (chelates Ca²⁺/Mg²⁺).
• Prevents redeposition of soil on fabrics.

2.2 Food Industry

• Retains moisture in processed meats (e.g., ham, sausages).
• Stabilizes pH in dairy products and canned goods.

2.3 Water Treatment

• Controls scaling in cooling towers (dosage: 0.5 mg/L achieves 95–100% scale inhibition).
• Acts as a corrosion inhibitor in industrial pipelines.

3. Usage Guidelines

3.1 Recommended Dosages

3.2 Storage & Safety

• Store in airtight containers at ambient temperature (avoid moisture).
• Use PPE (gloves, goggles) to prevent irritation from prolonged exposure.

4. Industry Case Studies

4.1 Textile Manufacturing

A textile plant in Zhejiang, China, integrated STPP into dyeing processes to improve color fastness and reduce water hardness, cutting chemical consumption by 18%.

4.2 Beverage Clarification

A juice producer used food-grade STPP (1.0 g/kg) to remove metallic ions, achieving 99% clarity and extending shelf life by 30%.
