Applications

1. For Food Processing And Meat Products: Tetrasodium pyrophosphate (TSPP, CAS 7722-88-5) is a food-grade additive used as a moisture retention agent, emulsifier and texture improver in meat, poultry, seafood and processed food products, helping lock in water and stabilize product quality.

2. For Detergents And Cleaning: TSPP acts as a builder and water softener in detergents and cleaning products, sequestering calcium and magnesium ions to boost cleaning power in hard water and supporting low-phosphorus formulations.

3. For Water Treatment And Scale Control: In industrial water systems, tetrasodium pyrophosphate works as a sequestering agent that binds calcium and magnesium ions, preventing scale formation in boilers, cooling circuits and process water.

4. For Electroplating And Surface Treatment: TSPP is used in the preparation of electroplating solutions as a complexing agent, and serves in metal surface treatment and textile processing as a dispersing and buffering aid.

5. For Ceramics And Industrial Formulations: As a dispersing and buffering agent, TSPP is applied in ceramic glazes, textile bleaching and other industrial formulations, giving manufacturers a versatile sodium phosphate salt for diverse processes.

Quality Assurance

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
