Product Description

Product Description

Sodium tripolyphosphate (STPP) is a multi-functional chemical compound, primarily used as a food additive, detergent builder, and in various industrial applications. It is a white, crystalline powder, soluble in water, with a slightly alkaline pH. 

Application

Food Additive:

• Preservative:

  STPP acts as a preservative, particularly for seafood, meats, and poultry, helping to retain moisture and improve texture. 

   
• Emulsifier:

  It functions as an emulsifier, preventing meat, poultry, or fish from becoming greasy and falling apart during heating. 

   
• Moisture Retention:

  STPP helps retain moisture in processed foods, improving their overall quality and shelf life. 

   
• Commonly Used:

  It's often found in processed cheeses, meat products, and seafood. 

   
• GRAS Status:

  The FDA recognizes sodium tripolyphosphate as Generally Recognized as Safe (GRAS) for use in food. 

   

Detergent Builder:

Water Softening: STPP is a key ingredient in detergents, acting as a water softener by sequestering calcium and magnesium ions, enhancing the cleaning power of surfactants.

Soil Removal: It aids in the removal of soil and dirt from fabrics.

Corrosion Inhibition: STPP can also act as a corrosion inhibitor in some cleaning applications. 

 

Industrial Uses:

Ceramics: Used as a deflocculant in ceramic slip preparation, helping to control viscosity and flow. 

Water Treatment: Employed in water treatment processes to control pH and prevent scaling. 

Other Applications: STPP finds uses in leather tanning, paper production, and as a dispersant in various industrial processes.
