Applications
1. For Heavy-Duty Cleaning And Degreasing: Trisodium phosphate (TSP, CAS 7601-54-9) is a strong alkaline cleaning agent used in heavy-duty cleaners, degreasers and stain removers, effectively removing grease, grime and residues from walls, floors, equipment and industrial surfaces.
2. For Detergents And Water Softening: TSP acts as a builder and water softener in detergent formulations, sequestering hardness ions and boosting cleaning performance in hard water across household and industrial laundry and dishwashing applications.
3. For Water Treatment And Boiler Care: In industrial water systems, trisodium phosphate softens water, controls alkalinity and prevents scale in boilers, helping maintain efficient heat transfer and protect boiler systems from scale deposits.
4. For Food Processing: As a food-grade additive, TSP functions as a pH regulator and emulsifier in processed foods, dairy products and cereals, supporting stable texture and quality in food manufacturing.
5. For Metal And Industrial Surface Treatment: TSP is used as a rust inhibitor, phosphating agent and metal cleaner in metal surface preparation, and supports textile mercerizing and scouring processes as an alkaline processing aid.
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.
