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
