Description

Mgda-3Na is the trisodium salt of methylglycine diacetic acid, a high-performance, readily biodegradable chelating agent and complexing agent. Its superior sequestering power for a wide range of metal ions, particularly calcium and magnesium, makes it a critical component in formulations requiring excellent stability under challenging conditions. This product is essential for industries such as detergents, personal care, pulp & paper, and water treatment, where it enhances cleaning efficiency, prevents scale formation, and stabilizes active ingredients.

Application

• Detergent & Cleaning Formulations: As a powerful builder and co-builder to sequester water hardness ions, enhancing surfactant performance and preventing inorganic deposits.
• Personal Care Products: Used in shampoos, liquid soaps, and creams as a stabilizing and chelating agent to improve product clarity, viscosity, and shelf-life.
• Pulp & Paper Industry: Employed in bleaching processes to chelate transition metals, thereby protecting cellulose and improving bleaching efficiency.
• Industrial & Institutional (I&I) Cleaners: Key ingredient in acidic, alkaline, and neutral cleaners for hard surface cleaning, dishwashing, and laundry applications.
• Water Treatment: Acts as a scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Textile Processing: Used in dyeing and finishing baths to complex metal ions that could interfere with processes or affect color fastness.
• Agriculture: Serves as a chelating agent in micronutrient fertilizers and agrochemical formulations to improve nutrient availability.

Quality Control

Our Mgda-3Na 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 are available for every shipment upon request, providing full traceability and compliance assurance for your quality 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 material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to minimize exposure to atmospheric moisture.
