Trisodium Phosphate (TSP)
TSP is used as a germicide, emulsifier, acidity adjuster, chelating agent, moisture-retaining agent, and stabilizer in the food industry, and as a flocculant and nourishment agent in drinking water and fermentation processes. Industrial grade serves as a water softener, boiler cleaning agent, detergent, and rust inhibitor.
- Manufacturer since 1952 — batch-level Certificate of Analysis (COA) on every shipment
- Long-term supply contracts with committed monthly allocations, insulated from spot-market swings
