Sodium tripolyphosphate (STPP, sometimes STP or sodium triphosphate or TPP), with formula Na₅P₃O₁₀, is a polyphosphate of sodium. It is the sodium salt of triphosphoric acid. It is used in various applications such as a preservative for seafood, meats, poultry and pet foods. It is also used in toothpaste and as a builder in soaps and detergents, improving their cleansing ability. The United States Food and Drug Administration lists STPP as "generally recognized as safe", along with salt, vinegar, and baking powder.STPP is a solid inorganic compound used in a large variety of household cleaning products, mainly as a builder, but also in human foodstuffs, animal feeds, industrial cleaning processes and ceramics manufacture. STPP is widely used in regular and compact laundry detergents and automatic dishwashing detergents (in powder, liquid, gel and/or tablet form), toilet cleaners, surface cleaners, and coffee urn cleaners . It also provides a number of chemical functions including: sequestration of "water hardness", enabling surfactants to function effectively; pH buffering; dirt emulsification and prevention of deposition; hydrolysis of grease; and dissolving-dispersing dirt particles.
