Methylglycinediacetic Acid Trisodium Salt (MGDA): Yuanlian Chemical's Sustainable Chelating Solution

Introduction
As global environmental regulations tighten and industries prioritize sustainability, traditional phosphorous/nitrogen-based chelators face phase-out challenges. Methylglycinediacetic Acid Trisodium Salt (MGDA), an eco-engineered, high-performance chelating agent, is transforming industrial cleaning, detergent formulations, and water treatment. Yuanlian Chemical—a leading innovator in fine chemicals—leverages cutting-edge R&D and scalable production to deliver premium MGDA, empowering clients’ green transition.

1. Product Overview: Nature-Inspired, Eco-Responsible Chelation

Derived from glycine (a natural amino acid), MGDA undergoes molecular optimization—introducing methyl groups and dual acetate chains—to form a stable trisodium salt. Its core advantage lies in exceptional biodegradability:

• 100% OECD 301F-certified biodegradability within 28 days, decomposing into CO₂, H₂O, and mineral salts.

• Superior eco-profile vs. persistent chelators (EDTA/NTA/phosphonates), eliminating aquatic toxicity risks.

• Yuanlian’s MGDA adopts green synthesis protocols, ensuring end-to-end environmental compliance.

Property	Advantage
Metal Chelation Capacity	Binds Ca²⁺/Mg²⁺/Fe³⁺ ions with high stability constants (log K_Ca=6.8, log K_Mg=5.6).
Solubility & Stability	Water-soluble (>600g/L); stable across pH 2–14 and temperatures ≤100°C.
Compatibility	Synergizes with surfactants, bleaches (peracetic acid/H₂O₂), enzymes.
Eco-Safety	Low aquatic toxicity (EC50 >100mg/L), non-bioaccumulative, skin-friendly.
