In both industrial production and daily cleaning, issues such as efficiency loss, equipment wear, and product quality defects caused by metal ions are common challenges. High-performance chelating agents centered on Dissolvine M-40 (Sodium Methyl Glycine Diacetate, CAS 20549-08-5) have emerged as a key solution across diverse fields—from detergents and industrial cleaning to metal treatment—thanks to their powerful sequestration, environmental compatibility, and chemical stability.

Detergent Industry: Combating Hard Water, Replacing Phosphorus-Based Builders
In hard water, calcium and magnesium ions readily form insoluble precipitates with surfactants, reducing cleaning efficiency. Dissolvine M-40, through the carboxyl and amino groups in its MGDA molecule, rapidly chelates di- and trivalent metal ions, forming stable, water-soluble complexes. This effectively shields surfactants from hard water interference. In dishwashing detergents, it can replace traditional phosphorus-containing builders, preventing surfactant deactivation in hard water while also stabilizing peroxide-based bleaching agents to extend product shelf life. In automatic dishwasher applications, its strong ability to chelate transition metal ions such as iron and copper further prevents metal-catalyzed oxidation, ensuring consistently effective and stable cleaning performance.

Industrial Cleaning: Removing Scale, Enhancing Equipment Efficiency
In water circulation systems, such as those in boilers and heat exchangers, scale deposits from calcium and magnesium ions significantly impair heat transfer efficiency. By forming stable complexes with metal ions, Dissolvine M-40 not only helps dissolve existing scale but also prevents new deposits from forming. Its low molecular weight allows for excellent performance in short-contact-time cleaning, enabling rapid penetration and efficient metal ion sequestration. In sectors like power generation, brewing, and sugar production, this product helps maintain long-term operational efficiency, reducing energy waste and maintenance costs associated with scale buildup.

Metal Treatment: Stabilizing Processes, Improving Product Quality
Fluctuations in metal ion concentration in process baths can compromise reaction consistency during metalworking. As a stabilizer for these baths, Dissolvine M-40 helps maintain metal ion activity, ensuring reliability in processes such as electroplating and chemical deposition. Moreover, its chelating power neutralizes trace impurities (e.g., iron, copper ions), preventing their deposition on metal surfaces and thereby enhancing coating uniformity and corrosion resistance. In metal carrier applications, MGDA can also directionally transport metal ions to reaction sites, optimizing the chemical reaction pathway.

Environmental Profile: Low Toxicity, Readily Biodegradable
Dissolvine M-40 is classified as a non-hazardous substance, characterized by low toxicity and low ecotoxicity, and requires no hazardous labeling. Its biodegradability complies with EU Detergent Regulation requirements, resulting in low wastewater treatment costs and aligning with current environmental policies. From household cleaning to industrial applications, this product drives various industries toward sustainable development through its dual advantages of high performance and safety.

Whether solving hard water cleaning challenges or ensuring the stable operation of industrial equipment, Dissolvine M-40, with MGDA at its core, demonstrates the essential value of advanced chelators across multiple fields.
