Description
Phosphoric Acid 85% Food Grade
Phosphoric Acid 85% Food Grade (CAS 7664-38-2, molecular formula H3PO4) is a core commodity reagent used wherever reliable acid or alkali strength matters — from surface treatment and pH correction to downstream salt manufacture. China Chemicals supplies it at 85% w/w in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Orthophosphoric Acid, White Phosphoric Acid. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Acidulant in beverage and food manufacture
- Metal surface conversion and rust conversion coatings
- Phosphate salt and detergent builder production
- Fertiliser and animal feed phosphate manufacture
- Dairy and brewery CIP cleaning formulations
