Description

Trisodiumnitrilotriaceticacidmonohydrate CAS NO 18662-58-3 is the trisodium salt of nitrilotriacetic acid (NTA), a versatile aminopolycarboxylic acid chelating agent. This compound is valued for its strong sequestering power towards di- and trivalent metal ions, such as calcium and magnesium, making it a key component in formulations where water hardness control is critical. It is primarily utilized by manufacturers in the detergent, cleaning product, textile processing, and water treatment industries.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions, enhancing the cleaning efficiency of surfactants in laundry detergents, industrial cleaners, and dishwashing products.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to chelate metal ions that can interfere with chemical processes and cause fabric discoloration or spots.
• Water Treatment: Employed in boiler and cooling water systems to prevent scale formation by binding calcium and magnesium ions, improving heat transfer efficiency and operational safety.
• Pulp & Paper Industry: Serves as a chelant in bleaching processes (e.g., hydrogen peroxide bleaching) to deactivate trace metals that catalyze peroxide decomposition.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and cosmetic formulations to stabilize products by preventing metal-catalyzed oxidation and rancidity.
• Industrial Cleaning: A key ingredient in metal cleaning and electroplating solutions to complex interfering metal ions and ensure surface quality.
• Agriculture: Used in some fertilizer and micronutrient formulations to improve the availability of essential metal ions to plants.
• Laboratory & Analytical Chemistry: Applied as a buffer component and metal ion masking agent in various complexometric titrations and analytical procedures.

Quality Control

Our Trisodiumnitrilotriaceticacidmonohydrate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture.
