Industry Wise Application
Agricultural Industry
- Fertilizer Production: Roughly 80-90% of phosphoric acid is used to produce phosphate fertilizers (e.g., DAP, MAP, TSP).
- Animal Feed Additive: Used in poultry and livestock feed as a nutritional additive and flavouring agent.
Food & Beverage Industry
- Acidulant: Provides a tart, tangy, or sour taste in colas, jams, and processed foods.
- Preservative: Acts as a preservative by inhibiting the growth of mold and bacteria.
- pH Regulation: Used to control acidity in dairy products, such as cheese
Pharmaceutical & Personal Care
- Dentistry: Acts as an etching solution to clean and roughen tooth surfaces for fillings.
- Medications: Used in anti-nausea medicines and to acidify urine.
- Personal Care: Adjusts pH in cosmetics, hair care products, and skincare products
Industrial Application
- Rust Removal: Directly removes rust (iron oxide) from steel and iron, turning it into water-soluble iron phosphate.
- Metal Surface Treatment: Used in metal finishing and phosphating to prevent corrosion and improve paint adhesion.
- Water Treatment: Controls pH and acts as a corrosion inhibitor in pipes, boilers, and cooling towers.
- Industrial Cleaner: Used to remove mineral deposits, concrete smears, and hard water stains.
