Description

Trisodium Nta CAS NO 10042-84-9 is the trisodium salt of nitrilotriacetic acid, a versatile and powerful aminopolycarboxylate chelating agent. This compound is critical for controlling metal ion concentrations in complex aqueous systems, preventing scale formation and stabilizing product formulations. It is an essential raw material for manufacturers in the detergent, textile, pulp & paper, and water treatment industries seeking effective and cost-efficient sequestration.

Application

• Detergent & Cleaning Formulations: Acts as a primary builder to soften water by chelating calcium and magnesium ions, enhancing surfactant performance and preventing scale in industrial and institutional cleaners.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to sequester metal ions that can cause fabric discoloration, degrade peroxide bleaches, or interfere with dye uptake.
• Pulp & Paper Production: Prevents metal-catalyzed decomposition of hydrogen peroxide during pulp bleaching, improving brightness and yield while protecting equipment from scale.
• Industrial Water Treatment: Controls water hardness in cooling towers, boilers, and closed-loop systems to inhibit scale and corrosion, improving heat transfer efficiency and system longevity.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and other formulations to stabilize ingredients, enhance foaming, and improve clarity.
• Agriculture & Chelated Micronutrients: Serves as an intermediate in the synthesis of chelated fertilizers, improving the bioavailability of essential micronutrients like iron, zinc, and manganese for plants.

Quality Control

Our Trisodium Nta 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 provided with every shipment to guarantee consistent quality and traceability for your production processes.

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 original container must be kept tightly sealed after use to prevent caking and degradation due to moisture absorption.
