Phosphoric Acid is one of the most versatile mineral acids used across food, pharmaceutical, chemical, and industrial sectors. It is a clear, colorless, and odorless liquid with a mild acidity that makes it ideal for use as a pH regulator, acidulant, and mineral source. All Chem supplies high-purity food-grade and technical-grade phosphoric acid suitable for a wide range of applications.
Phosphoric Acid is one of the most versatile mineral acids used across food, pharmaceutical, chemical, and industrial sectors. It is a clear, colorless, and odorless liquid with a mild acidity that makes it ideal for use as a pH regulator, acidulant, and mineral source. Phosphoric Acid (H₃PO₄) is a triprotic inorganic acid produced by the reaction of phosphorus pentoxide (P₂O₅) with water. Depending on its purity, it is used in both food-grade and industrial-grade applications.
In the food industry, Phosphoric Acid functions as an acidity regulator (E338) in carbonated beverages, sauces, dairy products, and processed foods. Industrial uses include metal cleaning, surface treatment, phosphate coating, and detergent formulation.
