INTRODUCTION

Tetrasodium pyrophosphate (TSPP) anhydrous is a white, crystalline or granular inorganic compound, soluble in water but insoluble in alcohol. TSPP is widely used in food, industrial, and cleaning applications due to its sequestrant, dispersing, buffering, and emulsifying properties.

MANUFACTURE

TSPP anhydrous is produced through the thermal dehydration of hydrated forms of TSPP or by direct high-temperature processing of disodium phosphate.

SynonymsSodium pyrophosphate
Tetrasodium diphosphate
CAS no.7722-88-5

Structure

APPLICATIONS

Food Industry:
Used as an emulsifier, texturizer, and thickening agent in processed meats, dairy products, and seafood.
Acts as a chelating agent, preventing the precipitation of calcium and magnesium ions.
Helps retain moisture in food products.
Detergents & Cleaning Agents:
Commonly found in household and industrial detergents due to its ability to soften water and enhance cleaning efficiency.
Used in toothpaste formulations to prevent tartar buildup.
Industrial Applications:
Used in ceramics, water treatment, and as a dispersing agent in paints and coatings.
Plays a role in metal finishing and electroplating processes.
