Sodium pyrophosphate decahydrate is widely used as a food additive, primarily functioning as an emulsifier, thickening agent, and stabilizer. It helps improve the texture and consistency of processed foods such as canned seafood, meats, and dairy products. In the cleaning industry, it serves as a key ingredient in detergents and cleaning agents due to its ability to soften water and enhance the effectiveness of surfactants. Additionally, it is employed in industrial applications, such as controlling pH levels in water treatment processes and acting as a dispersing agent in ceramic and paint production. Its ability to sequester metal ions makes it valuable in preventing scale formation and corrosion in various systems.
