Tripolyphosphate.
Appearance: White powder or granules.
Solubility: Readily soluble in water.
Aqueous Solution Property: Its water solution is alkaline.
Main Functions: It has two key chemical characteristics:
Chelation: It can bind with metal ions in water (such as calcium, magnesium, and iron ions) to form soluble complexes. This is the core principle behind its use as a water softener and detergent builder.
Dispersion: It can disperse and emulsify dirt and solid particles, preventing them from redepositing onto fabrics or tableware.
Sodium Tripolyphosphate was once the most important builder in synthetic detergents and also has a wide range of other applications:
Detergent Industry (Primary Use)
Softening Hard Water: By binding with calcium and magnesium ions, it improves detergent efficiency in hard water and prevents soap scum formation.
Enhancing Soil Removal: Its dispersive action helps the primary surfactants remove stains more effectively and prevents soil from redepositing.
Buffering Action: Maintains the wash liquor in an optimal alkaline pH range for improved cleaning.
Food Industry (as a Food Additive)
Meat Products: Used in ham, sausages, surimi, etc., to improve water retention, resulting in a tender texture and higher product yield.
Seafood: Used in treating frozen shrimp, fish, etc., to reduce drip loss upon thawing.
Dairy Products: Used in cheese and dairy beverages as a stabilizer and emulsifier.
In food, it is used as a moisture retention agent, quality improvement agent, and pH regulator. Its international code as a food additive is E451(i).
Common Applications:
Industrial Applications
Water Treatment: Used as a water softener and corrosion inhibitor in industrial cooling water systems.
Ceramics Industry: Serves as a deflocculant for ceramic slips.
Drilling Muds: Used as a dispersant.
Textile Dyeing: Used as an auxiliary agent.
