Polyphosphates are a class of chemical compounds consisting of multiple phosphate groups linked together. They are linear or branched polymers of orthophosphate units. The general formula for a linear polyphosphate can be represented as PnO3n+1^(n+2)- or [PO3]-n, where n is the number of phosphate units. These compounds occur naturally in biological systems and are also synthesized for various industrial and commercial applications. In nature, polyphosphates play roles in energy storage and as signaling molecules in microorganisms. Longer chain polyphosphates are found in bone and teeth, contributing to their structural integrity. Industrially, polyphosphates are widely used as food additives, often designated by the E-number system in Europe. They function as emulsifiers, stabilizers, sequestrants, and leavening agents in processed foods. Examples include their use in processed cheeses, meats, and baked goods. They are also employed in water treatment to prevent corrosion and scale formation, and in detergents to sequester metal ions, enhancing cleaning effectiveness. The properties and applications of polyphosphates are highly dependent on the length of the phosphate chain and the presence of associated cations.
