Description

Tetrasodium salt is a specialized chemical compound with the CAS registry number 97772-98-0. This material serves as a high-performance chelating agent and sequestrant, critical for controlling metal ions in complex industrial processes. It is essential for manufacturers in sectors such as water treatment, pulp & paper, and detergent formulation who require reliable scale inhibition and stabilization.

Application

• Water Treatment: Acts as a powerful scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Enhances cleaning efficiency by sequestering calcium and magnesium ions, preventing soap scum and improving surfactant performance.
• Pulp & Paper Industry: Used in bleaching processes to stabilize peroxides and control transition metal ions, improving brightness and pulp yield.
• Textile Processing: Serves as a chelant in dyeing and bleaching baths to prevent metal-ion catalyzed degradation of fabrics and dyes.
• Industrial Cleaning: Key component in acid and alkaline cleaners for industrial equipment, where it controls water hardness and enhances soil removal.
• Oilfield Chemicals: Employed in scale squeeze treatments and as a component in drilling fluids to manage mineral scaling.

Quality Control

Our Tetrasodium salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, chelation value, and physical properties. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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); ensure containers are kept sealed to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
