Monosodium Phosphate (MSP)
MSP is used as an acidity adjuster, emulsifier, and water-retaining agent in the food industry, and as a nourishment substance in fermentation. In feed processing, sodium dihydrogen phosphate serves as a mineral element source for farmed animals.
- 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
- Third-party pre-shipment inspection (SGS / BV) welcomed on request
