Applications Across Industries

Trisodium acid pyrophosphate CAS No. 14691-80-6 delivers targeted functionality through its chelating and buffering capabilities:

• Food and Beverages: Acts as a sequestrant and emulsifier in processed meats, poultry, and seafood to retain moisture and prevent discoloration; serves as a leavening agent in baked goods and a stabilizer in dairy products like cheese and non-dairy creamers, approved as GRAS (E450(ii)).

  
  

• Pharmaceuticals: Utilized as a buffering agent in oral suspensions and effervescent formulations; enhances solubility of active ingredients in nutritional supplements.

  
  

• Personal Care and Cosmetics: Incorporated into shampoos, soaps, and lotions as a chelator to soften water and improve lather stability.

  
  

• Water Treatment and Cleaning: Functions as a scale inhibitor and dispersant in detergents and boiler systems, binding calcium and magnesium ions to prevent deposits.

  
  

• Industrial Processes: Employed in metal surface treatments and textile dyeing as a complexing agent, improving adhesion and color fastness.

  
  

Choosing TSAPP supports sustainable manufacturing by reducing additive volumes and extending product shelf life.

Benefits of Choosing Trisodium Acid Pyrophosphate CAS No. 14691-80-6

• Enhanced Stability: Strong metal ion sequestration minimizes oxidation and enzymatic browning, preserving freshness in perishable goods.

  
  

• Neutral Buffering: Maintains optimal pH without altering flavor, ideal for sensitive taste profiles in beverages and confections.

  
  

• Safety and Compliance: Low acute oral toxicity (LD50 >4,640 mg/kg in rats); allergen- and GMO-free, suitable for diverse dietary needs.

  
  

• Process Optimization: Superior cold-water solubility accelerates mixing and yields higher moisture retention (up to 10% more in brines) compared to other phosphates.

  
  

Trisodium acid pyrophosphate CAS No. 14691-80-6 empowers formulators to achieve premium textures and longer-lasting products with eco-conscious efficiency.

Frequently Asked Questions (FAQs)

What is trisodium acid pyrophosphate CAS No. 14691-80-6 used for in food processing?

Trisodium acid pyrophosphate CAS No. 14691-80-6 is employed as a sequestrant, emulsifier, and moisture retainer in meats, seafood, and baked goods, binding metal ions to prevent spoilage and improve yield during cooking.

Is trisodium acid pyrophosphate CAS No. 14691-80-6 soluble in cold water?

Yes, it exhibits excellent solubility in cold brines and solutions, outperforming disodium variants for rapid dissolution in pre-salting processes without residue.

What pH range does trisodium acid pyrophosphate CAS No. 14691-80-6 provide in formulations?

It delivers a neutral pH of 6.7–7.5 in 1% solutions, making it suitable for pH adjustment in neutral to slightly alkaline foods like dairy and canned products without sourness.

Does trisodium acid pyrophosphate CAS No. 14691-80-6 meet international food additive standards?

Absolutely; it complies with FCC, USP/NF, and EU E450(ii) regulations, with limits typically at 0.1–0.5% in applications, ensuring safe consumption.

How does trisodium acid pyrophosphate CAS No. 14691-80-6 differ from tetrasodium pyrophosphate?

Trisodium acid pyrophosphate (Na₃HP₂O₇) is partially acidic for milder buffering, while tetrasodium (Na₄P₂O₇) is fully alkaline; TSAPP offers better solubility in neutral systems for meat processing.

Can trisodium acid pyrophosphate CAS No. 14691-80-6 be used in industrial detergents?

Yes, its chelating properties effectively soften water and disperse soils, enhancing cleaning efficiency in household and institutional formulations.
