Wholesale STPP (Sodium Tripolyphosphate) – Complete Buyer’s Guide
Sodium Tripolyphosphate (STPP) is one of the most in-demand inorganic phosphate chemicals in the detergent, food-processing, and industrial sectors. For importers, distributors, factories, and formulation manufacturers, selecting the right wholesale STPP supplier is crucial for quality, price stability, and long-term cooperation.
This guide provides a complete, technically detailed overview of STPP grades, specifications, bulk applications, prices, and how to choose a reliable manufacturer.
1. What Is Sodium Tripolyphosphate (STPP)?
STPP (Na₅P₃O₁₀) is valued for its strong chelating, dispersing, moisture-retaining, and emulsifying performance. It plays a critical role in detergents, food processing, ceramics, industrial cleaning, and water treatment.
- Chelation: binds Ca²⁺ and Mg²⁺ ions
- Dispersing: keeps particles suspended
- Buffering: maintains pH 9.5–10.5
- Moisture retention: improves food texture
- Emulsification: stabilizes cleaning formulations
