Tetrasodium pyrophosphate (TSPP) is a white, crystalline powder that is commonly used as a food additive, in detergents and cleaning products, and in Water Treatment. Its chemical formula is Na4P2O7 and its CAS number is 7722-88-5.

In food, TSPP is used as a buffering agent, emulsifier, and thickening agent. It is often added to processed cheese, canned seafood, and meat products to improve their texture and prevent spoilage. TSPP is also used in baking powder to help dough rise and in soft drinks to prevent them from becoming cloudy.

In cleaning products, TSPP is used as a water softener and to help remove stains and dirt. It is also used in water treatment to prevent the buildup of scale and to control the growth of algae and bacteria.

While TSPP is generally considered safe for use in food and cleaning products, it can be harmful if ingested in large quantities. It may cause irritation to the skin, eyes, and respiratory system if it comes into contact with these areas. As with any chemical, it is important to handle TSPP with care and to follow all safety precautions when using it.
