Phosphrous Acid

We are a Maharashtra, India based organization that imports, supplies and distributes premium grade Phosphrous Acid, which is an inorganic mineral acid with the chemical formula H3PO4. Also known as orthophosphoric acid, this is widely used in dentistry as an etching agent for cleaning and roughening of teeth after which, filling process takes place. In food products like colas, jams, sauces or ketchups etc. the phosphoric acid is used to regulate the acidity in order to provide tangy or sour taste.
