MGDA-Na3 Supplier: Trisodium Methylglycine Diacetate for Phosphate-Free Cleaning

Phosphate bans have reshaped detergent formulations, and MGDA-Na3 has become a standard answer. This glycine-derived chelant binds magnesium and stays stable at high pH, which makes it the usual choice for automatic dishwashing and heavy-duty laundry. As an MGDA-Na3 supplier, Yuanlian produces the material at scale, with the specifications and support that buyers need to reformulate without disruption.

Our Shandong plant runs dedicated synthesis lines for MGDA-Na3, and annual capacity across the green chelator range exceeds 12,000 tonnes. In-house laboratories verify each batch before release.

What MGDA-Na3 Brings to a Formula

MGDA-Na3 derives from glycine, a simple amino acid. It excels at magnesium chelation and keeps its structure in hot, alkaline conditions where other chelants break down. That stability lets it protect surfactants and peroxides in demanding wash cycles.

Like GLDA, it is readily biodegradable under OECD 301 and leaves no persistent residue. Formulators can drop phosphate builders and EDTA together, which simplifies compliance across several markets at once. Its pH stability spans roughly 2 to 13.5, so it survives both acidic descalers and strongly alkaline detergents.

MGDA-Na3 Supplier Specifications

Before any change, buyers need firm numbers. Typical MGDA-Na3 (Trisodium Methylglycine Diacetate) specifications from our line include:

Property	Typical value
Appearance	Clear, light yellow liquid
Active content	40–47% (grade dependent)
pH (as supplied)	10–12
Density	~1.25 g/cm³
INCI name	Trisodium Methylglycine Diacetate
CAS number	164462-16-2
Biodegradation	OECD 301, readily biodegradable

Grades differ by active content and packaging, so we confirm exact values during the customisation review and record them on the Certificate of Analysis for every shipment.

Working with an MGDA-Na3 Supplier on Dishwashing

Spotting and filming on glass come from magnesium and calcium during the hot, alkaline dish cycle. MGDA-Na3 prevents those deposits and helps rinse aids work. Tablet and powder makers build it into the matrix so each dose releases evenly, which delivers clear glass without a phosphate builder. Since the EU banned phosphates in dishwasher tablets from 2017, MGDA-Na3 has taken the role STPP once held.

MGDA-Na3 for Laundry

Laundry liquids run hot and alkaline, and magnesium drives grey filming on fabrics. MGDA-Na3 handles that load while supporting lower wash temperatures through peroxide stabilisation. The result is clean laundry with a smaller energy and environmental footprint.

MGDA-Na3 for Industrial and Institutional Cleaning

Factories, kitchens, and hospitals need scale and film control at volume. MGDA-Na3 supports descalers, floor cleaners, and degreasers while keeping effluent phosphorus low. Pairing it with a dispersant such as PASP-Na stops scale and holds particles suspended, which extends equipment life.

Why Choose Yuanlian as Your MGDA-Na3 Supplier

We hold ISO 9001 certification and operate as a recognised high-tech enterprise. Customisation covers active content, grade, and packaging, confirmed through batch testing before shipment. Options range from 25 kg drums to 1,250 kg IBC containers, matched to your handling and volume.

We export to more than 60 countries with sea and rail freight, and we prepare REACH, CBAM, and local import documents alongside the batch. Technical specialists advise on substitution ratios and compatibility, and we send samples for bench trials before full-scale change.

MGDA-Na3 Compared with Other Green Chelators

GLDA-Na4 rivals MGDA on calcium and broad pH, while IDS-Na4 covers iron and copper selectivity. MGDA-Na3 leads on magnesium and high-pH stability, which is why it anchors phosphate-free dish and laundry recipes. An MGDA-Na3 supplier that also stocks GLDA lets you cover both with one qualified source.

Regulatory Background Buyers Should Know

The EU banned phosphates in consumer laundry detergents and dishwasher tablets from 2017, which removed STPP from most European wash products. EDTA faces growing restriction because it resists degradation. MGDA-Na3 meets both pressures, which explains its rapid uptake in phosphate-free and clean-label formulations.

MGDA-Na3 in Textile, Pulp and Metal Cleaning

Textile mills use MGDA-Na3 to stabilise peroxide in bleaching and keep dye baths consistent. Pulp and paper lines use it for scale control on equipment. Metal cleaning and electronics lines use it to remove residues without persistent chemistry. In each, the biodegradable profile eases pressure on effluent treatment.

How an MGDA-Na3 Supplier Supports Your Substitution Trial

Replacement works best as a staged project. We start by reviewing your current chelator, target pH, and the metal ions causing faults. From that, we propose a starting substitution ratio and send a sample matched to your grade. You run a bench trial at your actual water hardness and temperature, then confirm the result before any plant change. Our technical staff stay available through the trial and help interpret the data, which shortens the path from evaluation to production. Most switches complete in two or three iterations, which keeps disruption to a minimum.

Storage and Handling

MGDA-Na3 is a liquid chelant supplied in drums or IBCs. Store it in a cool, dry place away from strong acids, and follow the shelf life on the SDS. As an alkaline product, avoid skin and eye contact and observe the handling guidance in the safety data sheet. Protect liquid grades from freezing, as low temperatures can affect viscosity.

Certificates and Samples from an MGDA-Na3 Supplier

Every shipment includes a Certificate of Analysis, with TDS and SDS available on request. To start, tell us your current chelator, target application, and volume. We return a recommendation, a quotation, and a sample for evaluation. Contact our sales team at [email protected] or call +86-537-3739818.

Frequently Asked Questions

Can MGDA-Na3 replace EDTA fully?

In most dish and laundry applications, yes. It matches EDTA on the metal ions and pH where it is designed to work. Correct selection, not a straight swap, gives the best result.

Do you provide REACH and CBAM documentation?

We supply the documents needed for import compliance and work with your representatives on substance-related requirements.

What is the minimum order quantity?

Standard MOQ starts at one pallet, with smaller trial quantities available for qualified formulators running evaluation batches.
