Dissolvine M-40 is a 40 weight percent solution of methylglycine N,N-diacetic acid trisodium salt (MGDA-Na3) in water, offering a readily biodegradable chelating agent for controlling metal ion reactivity in water-based systems. Formulators sourcing Dissolvine M-40 use it as a fast-working, strong builder that serves as a drop-in replacement for NTA and a phosphate alternative in automatic dish washing, laundry, and car care formulations.
What Is Dissolvine M-40?
Dissolvine M-40 is the liquid form of MGDA, chemically named methylglycine N,N-diacetic acid, trisodium salt, with chemical formula MGDA-Na3 (C7H8NO6Na3), CAS number 164462-16-2, EC number 423-270-5, molecular weight 271.1 g/mol, and INCI name trisodium dicarboxymethyl alaninate. MGDA has three carboxylic groups that, together with the central nitrogen atom, provide strong multiple bonds with di- and trivalent metal ions, enabling rapid action at low temperatures and short contact times.

Applications of Dissolvine M-40
This chelating agent is used across household cleaning, including automatic dish washing, laundry detergents, and surface cleaning, as well as industrial and institutional cleaning applications such as mechanical dish washing, cleaning-in-place, transport cleaning, hard surface cleaning, biocidal detergents, and metal cleaning. It also finds use in polymer production, textile processing, gas sweetening, membrane cleaning, metal plating, and electronics. In cleaning formulations, it outperforms widely used builders like phosphates, citrates, gluconates, and zeolites due to its stronger bonds with hard water ions.
Sustainability and Regulatory Profile
MGDA is readily biodegradable under multiple OECD test methods and has demonstrated anaerobic biodegradability under OECD 311, a requirement for European Ecolabel compliance. It is fully REACH registered, listed on the US EPA Safer Chemical Ingredients List, and compliant with Nordic Swan and EU Ecolabel detergent legislation. It contains 43% renewable carbon atoms as measured by ASTM method D6866, and does not require dangerous goods labeling.
Handling and Storage
It is chemically stable under both acid and alkaline conditions and is stable under normal and recommended storage conditions. Because of its high pH, it should be stored in corrosion-resistant containers such as stainless steel or plastic, avoiding contact with aluminum, zinc, copper alloys, copper, and nickel. It should not be combined with hypochlorite bleach. Buyers should confirm site-specific handling requirements against the current safety data sheet.
