What is Phosphoric Acid?
Phosphoric Acid is a mineral acid with broad application across food, agricultural, and industrial chemistry, supplied as a colourless, clear, syrupy liquid typically at 85% concentration. Food Grade Phosphoric Acid is one of the most widely used acidulants in the beverage industry, most notably providing the distinctive sharp, tangy flavour note in cola soft drinks, while Industrial Grade Phosphoric Acid serves essential roles in metal surface treatment, rust removal, and as a raw material for phosphate fertiliser production.
Polychem Industries supplies Phosphoric Acid in food grade and industrial grade to beverage manufacturers, metal treatment companies, and fertiliser producers across India and internationally. Its versatility as both a critical food acidulant and a fundamental industrial and agricultural raw material makes it one of the most important mineral acids in commercial use.
Corrosive Material Notice
Phosphoric Acid is a strongly corrosive liquid that can cause severe skin and eye burns on contact, particularly in concentrated form. Handle only with appropriate PPE including acid-resistant gloves, face shield, and protective clothing. Use acid-resistant storage and transfer equipment. Full MSDS documentation must be reviewed before handling.

Applications & Uses
Cola & Carbonated Beverages
One of the most recognised food applications. Food Grade Phosphoric Acid provides the characteristic sharp, tangy flavour note in cola and certain other carbonated soft drinks, while also contributing to product pH stability and microbial control.
Processed Cheese & Dairy
Used as an acidulant and pH adjusting agent in certain processed cheese and dairy product formulations, contributing to product texture and stability characteristics.
Baking & Food Processing
Used in certain baking applications and food processing formulations as an acidulant and leavening acid component, contributing to specific texture and flavour characteristics.
Rust Removal & Metal Surface Treatment
Industrial Grade Phosphoric Acid is widely used in rust removal products and metal surface treatment (phosphating) processes, converting iron oxide (rust) into a more stable phosphate compound while preparing metal surfaces for subsequent coating or painting.
Phosphate Fertiliser Production
Used as a key raw material in the production of various phosphate fertilisers, including monoammonium phosphate and other phosphate-based agricultural nutrients essential to global food production.
Industrial Cleaning & Water Treatment
Used in certain industrial cleaning formulations and water treatment applications requiring its specific acidic and phosphate chemistry for scale control and surface cleaning purposes.
