Description

Trisodium Hedta CAS NO 1330-54-7 is the trisodium salt of hydroxyethyl ethylenediaminetriacetic acid, a highly effective chelating agent. Its primary value lies in its superior sequestering power for a wide range of di- and trivalent metal ions, particularly under alkaline conditions where other chelants are less effective. This makes it an essential component for industries requiring precise metal ion control, such as industrial cleaning, textile processing, and personal care formulation.

Application

• Industrial & Institutional (I&I) Cleaning: Key chelant in heavy-duty alkaline cleaners, degreasers, and bottle washing formulations to prevent scale and inactivate metal ions that interfere with surfactants.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to sequester calcium, magnesium, and iron ions, ensuring consistent color and fabric quality.
• Personal Care & Cosmetics: Functions as a stabilizer and chelating agent in shampoos, liquid soaps, and creams to enhance shelf life and product performance by binding trace metals.
• Pulp & Paper Industry: Employed in bleaching processes to deactivate transition metal ions that catalyze the degradation of cellulose, improving pulp brightness and strength.
• Agriculture: Used in certain micronutrient fertilizer formulations and agrochemicals to improve the bioavailability of essential metal ions.
• Water Treatment: Acts as a scale inhibitor and dispersant in boiler and cooling water systems.
• Chemical Synthesis & Catalysis: Serves as a ligand or metal scavenger in various chemical manufacturing processes.

Quality Control

Our Trisodium Hedta 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. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profiles, and physical parameters is provided with every shipment to guarantee traceability and compliance for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking.
