CAS No.: 164462-16-2
Molecular Formula: C7H8NNa3O6 Molecular weight: 271.11
Property and Usage:
MGDA.Na3 is an excellent green chelating agent for a variety of applications. It has proven to be highly effective at removing difficult stains and bleaching while showing excellent toxicity, safety and biodegradability.
In addition to its impressive stain-fighting abilities, MGDA.Na3 can also form stable chelate complexes with metal ions in a wide range of pH levels, and it can even synergize with biocides in the system. This makes it suitable as a substitute for phosphonates, NTA, EDTA citrate, and other chelating agents commonly used in detergents.
MGDA.Na3 is also a useful stabilizer for sodium perborate and sodium percarbonate and works as an effective builder in non-phosphor detergent formulations. Its cleaning abilities are remarkable, too—it can prevent rancidity, color change, and dirt precipitation when added to soaps. And beyond that, it serves as both a scale remover and inhibitior, helping to clean indissolvable salt scales from various industries.

How to Package and Store MGDA.Na3
MGDA.Na3 is a chemical compound often used in cleaning products and industrial processes. To ensure that the product is stored properly, it’s important to follow the proper packaging and storage guidelines.
When packaging MGDA.Na3, use an air-tight container made from glass or plastic. Make sure that there are no cracks or other openings that allow moisture or oxygen into the container, as this can reduce the product’s effectiveness or even cause it to become hazardous. Before sealing the container, add a desiccant packet to remove any extra moisture from the air inside the packaging.
Once packaged, store MGDA.Na3 is away from direct sunlight in a cool, dry place for optimal shelf life and potency of the chemicals within it. It should also be kept away from heat, fire, and sparks as these can cause igniting and possible explosions if handled improperly. Do not store the product in areas with high humidity levels or exposure to weather conditions such as rain or snow since this could make it unusable after just a few hours of exposure. Finally, always keep MGDA.Na3 is out of reach of children, pets, and unauthorized personnel when mishandled due to its hazardous nature.
