Sodium Tripolyphosphate

Key SpecificationsData SheetsContact

Overview

Sodium Tripolyphosphate (STPP) is a versatile inorganic compound widely used as a cleaning agent, water softener, and food preservative. Known for its excellent sequestration properties, STPP binds calcium and magnesium ions, preventing scale formation and boosting cleaning efficiency. It is an essential ingredient in detergents and cleaning products, as well as in ceramics, textiles, and the oil drilling industry. Its ability to retain moisture also makes it valuable in food processing applications, such as in seafood and meat products.

STPP is lauded for its high solubility and effectiveness at controlling pH levels, making it indispensable in water treatment processes. With a long shelf life and easy handling, it ensures stable performance across a range of environments. Its wide range of applications highlights its role in both industrial and consumer products.
