MGDA-Na3: The Sustainable Chelating Agent Revolutionising Cleaning and Industrial Applications

In an era where environmental responsibility is paramount, industries across Europe are actively seeking high-performance, eco-friendly alternatives to traditional chemicals. Shandong Yuanlian Chemical Co., Ltd. is at the forefront of this shift with our premium-grade Trisodium Dicarboxymethyl Alaninate (MGDA-Na3), a next-generation, readily biodegradable chelating agent.

What is MGDA-Na3?

MGDA-Na3, or Methylglycine N,N-diacetic acid trisodium salt, is a powerful, small-molecule chelant with the CAS No. 164462-16-2. Its molecular structure is akin to traditional agents like NTA but is distinguished by its excellent biodegradability and non-toxic profile. As a phosphorus-free solution, it effectively replaces conventional phosphonates, EDTA, and NTA, aligning with stringent European regulations on water quality and environmental impact.

Key Specifications:

• Molecular Formula: C₇H₈NO₆Na₃

• Molecular Weight: 271.1

• Appearance: Available as a clear liquid (40-42%), white powder (≥85%), or white granules (≥78%).

• pH (1% solution): 10.0 - 12.0

Why Choose Yuanlian Chemical's MGDA-Na3?

1. Superior Environmental Profile: MGDA-Na3 meets the demand for green chemistry. It is readily biodegradable, minimising aquatic toxicity and long-term ecological persistence compared to older sequestrants.

2. Exceptional Chelating Performance: It exhibits outstanding solubility for scale-forming ions like calcium and magnesium, even in challenging conditions. It effectively tackles stubborn inorganic deposits, including carbonate and phosphate scales.

3. Versatility Across Industries: Our MGDA-Na3 is engineered to enhance performance in a wide array of applications.

Key Applications in Cleaning and Washing

• Fabric Detergents: Enhances stain removal (blood, sebum, milk, ink) in heavy-duty laundry formulations. It prevents soap scum formation and redeposition on fabrics, ensuring cleaner, brighter, and odour-free results.

• Phosphate-Free Automatic Dishwashing Detergents: A critical component in compliant EU dishwasher tabs and liquids. MGDA-Na3 significantly improves rinse aid performance, prevents filming, and is exceptionally effective against tough tea stains and starch residues.

• Industrial & Institutional Cleaning: Ideal for removing hardened inorganic scale (e.g., in dairy processing, heat exchangers, or RO membranes) without the corrosivity of acids. It converts insoluble salts into soluble complexes.

Commitment to Quality and Safety

Yuanlian Chemical ensures consistent, high-purity MGDA-Na3 production. While the product is alkaline and requires standard safety handling (use PPE, rinse with water upon contact), it represents a safer choice for formulations aimed at end consumers and the environment.

Available Packaging for Your Convenience:

• Liquid: 25kg, 250kg, 1250kg plastic drums.

• Powder & Granules: 25kg craft paper bags.

• Customised packaging options are available upon request.
