Description

Potassium Pyrophosphate (CAS NO 7320-34-5) is a versatile inorganic salt widely used as a buffering agent, emulsifier, and sequestrant in various industrial processes. Its high solubility and stability in aqueous solutions make it a critical component for controlling pH and chelating metal ions. This product is essential for manufacturers in the food processing, detergent, and water treatment industries seeking reliable and consistent chemical performance.

Application

• Food Industry: Used as an emulsifying salt in processed cheeses, a buffering agent, and a sequestrant to improve texture and shelf-life.
• Detergent & Cleaning Formulations: Acts as a builder to soften water, enhance cleaning efficiency, and prevent redeposition of dirt in laundry and dishwashing detergents.
• Water Treatment: Serves as a corrosion inhibitor and scale preventer in industrial water systems and cooling towers.
• Electroplating: Employed in electroplating baths for surface finishing and metal treatment processes.
• Ceramic & Clay Production: Functions as a dispersant to improve the workability and stability of ceramic slips and clay bodies.
• Oil Drilling Fluids: Used as a thinning agent and for controlling rheological properties in drilling muds.
• Textile Processing: Acts as a scouring and bleaching assistant in fabric preparation.

Quality Control

Our Potassium Pyrophosphate is manufactured under a stringent quality management system. We offer grades suitable for food, technical, and industrial applications, with production processes designed to ensure batch-to-batch consistency. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying are provided with every shipment to guarantee compliance with relevant specifications, including FCC for food-grade material.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in original packaging or a suitable moisture-proof container to prevent caking and degradation.
