Description

Nitrilotriacetic Acid Trisodium Salt Monohydrate is a high-purity chelating agent and sequestrant, essential for controlling metal ion activity in complex formulations. Its primary value lies in its ability to form stable, water-soluble complexes with a wide range of polyvalent metal ions, preventing unwanted precipitation and catalytic degradation. This makes it a critical component for manufacturers in the detergent, textile, pulp & paper, and water treatment industries seeking to enhance product stability and process efficiency.

Application

• Detergent & Cleaning Formulations: Acts as a builder and sequestrant to inactivate water hardness ions (calcium, magnesium), improving surfactant efficacy and preventing scale.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to complex metal ions that can cause fabric damage or uneven dyeing.
• Pulp & Paper Production: Chelates metal ions during bleaching processes to protect cellulose fibers and improve brightness.
• Industrial Water Treatment: Prevents scale formation and controls metal ion fouling in cooling towers, boilers, and reverse osmosis systems.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and creams to stabilize formulations and enhance shelf life.
• Chemical Synthesis & Catalysis: Serves as a ligand in various chemical processes and analytical chemistry applications.
• Agriculture: Used in certain fertilizer and micronutrient formulations to improve nutrient availability.

Quality Control

Our Nitrilotriacetic Acid Trisodium Salt Monohydrate is manufactured under a strict 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 are available for every shipment 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); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
