MGDA-3NA is a powerful chelating agent with excellent chelating ability for multiple metal ions.

• Calcium and magnesium ionsEffectively softens water, prevents scale formation
• Iron ionEspecially under high pH conditions, it effectively chelates trivalent iron ions, preventing discoloration and precipitation.
• Copper, Zinc IonsStable in washing and personal care formulations
• Manganese ionPrevents oxidation and discoloration

Its stability constant (log K) is approximately 13-14, providing good chelation for most divalent and trivalent metal ions.

MGDA-3NA exhibits excellent stability in high pH environments, which is one of its key advantages.

• Strong alkali resistanceMaintains excellent chelating ability at pH 12 and above without decomposition or failure
• Good thermal stabilityCan be used at temperatures up to 60°C, suitable for hot water washing formulations
• Hydrolysis resistantNot prone to hydrolysis under alkaline conditions, maintaining long-term stability.

This makes it especially suitable for applications requiring high alkalinity, such as laundry powders and dish detergents.

MGDA-3NA is a truly biodegradable chelating agent:

• Degradation rateBiodegradation rate >80% in 28 days, compliant with OECD 302B
• Degradation mechanismFirst decomposes under enzyme action into iminodiacetic acid and acetate intermediates
• Final productCompletely mineralizes into carbon dioxide, water, and nitrogen, leaving no harmful residues
• Environmentally FriendlyNo long-term accumulation risk in soil or water, does not affect microbial activity

MGDA-3NA has excellent compatibility with various surfactants:

• Anionic SurfactantGood compatibility with LAS, AES, AOS, etc., with no negative interactions
• Nonionic SurfactantSuch as alkoxylates, with good synergistic effect
• Amphoteric surfactantStable Compatibility
• Cationic SurfactantPay attention to formulation design; pre-testing is recommended

Compared to EDTA and NTA, MGDA-3NA does not form insoluble complexes with anionic surfactants, avoiding formulation cloudiness and performance degradation.

It is normal for MGDA-3NA liquid products to appear light yellow, due to:

• Sodium Salt PropertiesMGDA-3NA trisodium salt has a slight yellow color, which is its chemical characteristic
• Production processTrace impurities may be generated during synthesis, causing slight discoloration.
• Storage FactorsLong-term storage may slightly deepen the color, but does not affect quality

The light yellow color does not affect performance. In cleaning and detergent formulations, the typical dosage is 0.5-2%, and the color does not impact the final product appearance.

MGDA-3NA itself is non-corrosive to metals, but precautions should be taken when using:

• Storage ContainerPE, PP, and stainless steel 304/316 containers are recommended; avoid carbon steel and aluminum.
• Conveying systemStainless steel, plastic, or corrosion-resistant lined pipes should be used
• Compatibility NotesAvoid direct mixing with strong acids to prevent corrosion from excessively low local pH.
• Cleaning recommendationsRinse equipment with clean water after use to prevent residual solution concentration

At normal use concentrations (0.5-2%), MGDA-3NA is safe for stainless steel, plastic and other materials.
