Sodium Pyrophosphate Specification

PRODUCT LIST

Types of Sodium Pyrophosphate

FeaturePowder FormGranular Form
Dissolution SpeedVery fast – dissolves quickly due to larger surface areaSlightly slower – dissolves steadily, good for controlled mixing
Dust LevelHigher – may create dust during handlingLower – minimal dust, cleaner work environment
FlowabilityPoor – may clump or cake in humid conditionsExcellent – flows freely, ideal for automated systems
Caking TendencyHigher – absorbs moisture easily, requires careful storageLower – more stable, resists caking in storage
Best For• Liquid formulations requiring fast dissolution
• Laboratory or small-batch mixing
• Rapid chemical reactions		• Detergent and cleaning powder production
• Automated dosing systems
• Dry blends and large-scale manufacturing

Key Advantages of Sodium Pyrophosphate：

  • High Purity & Consistent Quality: Our Sodium Pyrophosphate has purity ≥96%, ensuring reliable and stable performance across all your formulations.

  • Strong Metal Ion Chelation: It effectively binds with calcium, magnesium, iron, and other metal ions, preventing scale formation and improving cleaning efficiency.

  • Excellent pH Buffering Capacity: With a 1% solution pH of 10.0-10.2, it maintains stable alkaline conditions ideal for detergents, food processing, and industrial applications.

  • Multi-Form Availability: We supply both powder and granular forms to match your production needs — powder for fast dissolution, granules for low dust and easy handling in automated systems.

  • Safe & Certified Food Additive: Approved as a food additive (INS 450, E450), it meets international food safety standards for use in meat, seafood, and processed foods.

What is Sodium Pyrophosphate Used for

  • Food Industry: Used for pH control, texture improvement, and ingredient stabilization in processed foods.

  • Detergent Manufacturing: Softens water, aids dispersal, and enhances detergent cleaning efficiency.

  • Water Treatment: Prevents scale formation in pipes, boilers, and cooling systems.

  • Industrial Use: Acts as a chelating agent, improves solution stability, and aids in metal cleaning and electroplating.

  • Laboratory and Research: Used as a reagent in chemical reactions and in buffer solutions.

 

FAQ of Sodium Pyrophosphate

Yes, it is classified as “generally recognized as safe” (GRAS) by the U.S. FDA when used according to regulations. It is commonly used as a food additive (E450) in processed meats, seafood, and baked goods.

It can cause skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335) if dust is inhaled . It is not classified as highly toxic — oral LD50 is 4000 mg/kg (rat).
