Description

Tetrasodium Pyrophosphate (CAS NO 7722-88-5) is an inorganic salt widely recognized for its powerful sequestering, buffering, and emulsifying properties. This versatile compound is essential for controlling water hardness, stabilizing pH, and improving texture in numerous industrial processes. It is a critical ingredient for manufacturers in the food processing, detergent, water treatment, and ceramics industries seeking reliable and effective performance.

Application

• Food Industry: Used as an emulsifier, buffering agent, and texturizer in processed meats, seafood, and dairy products to improve moisture retention and stability.
• Detergent & Cleaning Formulations: Acts as a water softener and builder in industrial and household detergents, enhancing cleaning efficiency by chelating metal ions.
• Water Treatment: Employed as a scale inhibitor and corrosion control agent in industrial water systems and boiler water treatment.
• Ceramics & Electroplating: Serves as a dispersant in ceramic glazes and as a component in electroplating baths for surface treatment processes.
• Oil & Gas Drilling: Functions as a mud thinner and viscosity control agent in drilling fluid formulations.
• Textile Processing: Used in scouring and bleaching baths to sequester calcium and magnesium ions, improving process efficiency.

Quality Control

Our Tetrasodium Pyrophosphate is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. We offer various grades, including Food Grade (FCC) and Technical Grade, each meeting stringent specifications for purity and performance. A Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, heavy metal content, and loss on drying.

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); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
