Phosphoric acid (H3PO4) is a colorless, odorless, syrupy liquid that is widely used in various industries.
Fertilizers (around 90% of production): The primary use of phosphoric acid is in the production of fertilizers. When phosphoric acid reacts with minerals like calcium carbonate, it produces phosphate salts, essential for plant growth.
Food and Beverages (as an acidity regulator and flavoring agent): Food-grade phosphoric acid, also known as E338, is used as an acidulant and flavoring agent in various food and beverage products. It adds a tangy taste to soft drinks, jams, and processed foods, and also acts as a preservative.
Personal Care Products: Phosphoric acid is used in various personal care products like shampoos, soaps, detergents, cosmetics, and toothpaste. It helps control the pH level of these products and can also act as a chelating agent, binding to metal ions in hard water.
Metal Treatment: Phosphoric acid is used in a metal treatment process called parkerizing to create a conversion coating on the surface of steel. This phosphate coating improves the adhesion of paint and helps prevent corrosion.
Other Uses: Phosphoric acid has a variety of other applications, including:
