MGDA-3Na

Overview

MGDA-3Na 40% Liquid (trisodium methylglycine diacetate) is a high-performance, biodegradable chelating agent designed for efficient metal ion control in a wide range of applications. Based on a simple amino acid structure, MGDA offers excellent chelation strength, particularly for divalent ions, while maintaining a favorable environmental profile. It is highly soluble, performs best in neutral to alkaline conditions, and provides a cost-effective and sustainable alternative to traditional chelants such as EDTA.

MGDA-3Na (methylglycine-N,N-diacetic acid, trisodium salt) is a tridentate aminopolycarboxylate. Its structure contains three carboxylate groups and one nitrogen atom, enabling effective complexation with divalent metal ions such as Ca²⁺, Mg²⁺, Zn²⁺, and Cu²⁺. MGDA is most stable and effective in neutral to high pH environments, where it delivers strong chelation efficiency and formulation stability.
