Applications
1. For Detergents And Laundry Products: Sodium tripolyphosphate (STPP, CAS 7758-29-4) is a proven builder in laundry and dishwashing detergents, binding calcium and magnesium ions to soften water, enhance surfactant efficiency and improve soil removal across washing formulations.
2. For Food Processing And Seafood: As a food-grade additive, STPP works as a moisture retention agent, emulsifier and quality improver in processed meat, poultry, seafood and canned products, helping preserve moisture, texture and color stability.
3. For Ceramics And Clay Processing: In ceramic manufacturing, STPP acts as a dispersant and deflocculant for clay slips and slurries, reducing water content and improving uniformity and flow properties in tile and sanitaryware production.
4. For Water Treatment And Industrial Processing: STPP is used as a sequestrant and water softener in industrial water systems, and supports leather pre-tanning and textile dyeing processes as a dispersing and buffering agent.
5. Reliable Supply For Global Industry: Supplied in food-grade and technical-grade powder with consistent quality, STPP gives detergent, food, ceramic and water treatment manufacturers a dependable phosphate with stable supply, flexible packaging and professional technical support.
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.
