Description

Zinc Dihydrogen Diphosphate is an inorganic zinc salt of diphosphoric acid, widely recognized for its functional properties as a sequestrant, stabilizer, and nutrient source. This compound is valued in industrial and specialty chemical applications for its ability to modify texture, control pH, and deliver bioavailable zinc. Key industries that utilize this material include food processing, where it acts as an emulsifying salt, and industrial manufacturing, where it serves as a corrosion inhibitor and flame retardant synergist.

Application

• Food Additive: Used as an emulsifying salt and texture modifier in processed cheese, dairy products, and meat analogs.
• Nutrient Fortification: Serves as a source of bioavailable zinc in dietary supplements and fortified food products.
• Industrial Corrosion Inhibition: Functions as a component in coatings and treatment solutions to protect metal surfaces.
• Flame Retardant Synergist: Enhances the effectiveness of halogen-based flame retardants in polymers and plastics.
• Ceramic & Glass Production: Acts as a flux and stabilizer to modify melting points and improve product durability.
• Detergent Builder: Improves cleaning efficiency in industrial and institutional cleaning formulations by sequestering water hardness ions.

Quality Control

Our Zinc Dihydrogen Diphosphate is manufactured under a strict quality management system. Production adheres to relevant industry standards, including potential compliance with FCC (Food Chemicals Codex) guidelines for food-grade applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) documenting key specifications is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric humidity. Keep away from incompatible materials such as strong acids and strong bases.
