GLDA-Na4 Supplier: Tetrasodium Glutamate Diacetate for Clean Formulations

Formulators across Europe have moved away from persistent chelators, and GLDA-Na4 sits high on the shortlist. This amino-acid-derived chelant binds calcium and magnesium as well as EDTA yet breaks down in the environment after use. As a GLDA-Na4 supplier, Yuanlian produces the material at volume, with the documentation and technical backing that buyers need to switch with confidence.

Our plant in Shandong runs dedicated synthesis lines for GLDA-Na4, and annual capacity across the green chelator range exceeds 12,000 tonnes. Each batch passes in-house laboratory checks before release.

What GLDA-Na4 Offers Formulators

GLDA-Na4 comes from glutamic acid, a naturally occurring amino acid. It shows strong calcium binding across a wide pH window, from neutral through strongly alkaline. That broad tolerance lets it work in laundry liquids, industrial cleaners, and personal care products without a separate grade for each pH.

Independent assessment places GLDA's natural-origin index at 0.56 under ISO 16128, ahead of other strong chelators. Because the molecule is readily biodegradable under OECD 301, it leaves no persistent residue in wastewater. Formulators can make clean-label claims that survive scrutiny, which matters as retailers tighten restricted-substance lists.

GLDA-Na4 Supplier Specifications

Buyers need firm numbers before they change a formula. Typical GLDA-Na4 (Tetrasodium Glutamate Diacetate) specifications from our line include:

Property	Typical value
Appearance	Clear, light yellow liquid
Active content	38–47% (grade dependent)
pH (as supplied)	10–12
Density	~1.25 g/cm³
INCI name	Tetrasodium Glutamate Diacetate
CAS number	51981-21-6
Biodegradation	OECD 301, readily biodegradable

Figures vary with the grade you choose, so we confirm the exact values during the customisation review and record them on the Certificate of Analysis for every shipment.

Working with a GLDA-Na4 Supplier on Detergents and Cleaning

Hard water deposits calcium and magnesium on fabrics, glass, and surfaces. GLDA-Na4 sequesters those ions so surfactants can lift soil instead of fighting scale. In industrial and institutional cleaning, it also helps stop soil from redepositing, which keeps results consistent across wash cycles.

Several large retailers now list EDTA as a substance to phase out. A GLDA-Na4 supplier that can document biodegradability makes that transition straightforward rather than disruptive.

GLDA-Na4 for Personal Care

Personal care products need metal-ion control to protect oils, fragrances, and preservatives from oxidation. GLDA-Na4 performs this role at low use levels and carries a favourable toxicology profile, which suits rinse-off and leave-on recipes alike. Its compatibility with sensitive-skin positioning helps brands meet clean-beauty expectations.

GLDA-Na4 for Water Treatment and Agriculture

In cooling water and boilers, GLDA-Na4 controls calcium scale without adding phosphorus to the effluent. In agriculture, it acts as a fertiliser additive that reduces scaling in dosing systems and improves nutrient availability. Both uses answer the same regulatory push against phosphate discharge.

Why Choose Yuanlian as Your GLDA-Na4 Supplier

We hold ISO 9001 certification and operate as a recognised high-tech enterprise. Customisation is part of the service: we adjust active content, packaging, and grade to your specification, then confirm it through batch testing. Packaging runs from 25 kg drums to 1,250 kg IBC containers, aligned to your volume and handling.

Our sales team coordinates sea and rail freight to more than 60 countries, with documentation for REACH, CBAM, and local import needs prepared alongside the batch. Technical specialists answer questions on substitution ratios and compatibility, and we supply samples for bench testing before any full-scale change.

GLDA-Na4 Compared with Other Green Chelators

MGDA-Na3 rivals GLDA on magnesium and high-pH stability, while PASP-Na and IDS-Na4 cover scale and metal-selective roles. GLDA-Na4 holds the advantage on broad calcium control at moderate alkalinity, which fits most household and industrial cleaners. A GLDA-Na4 supplier that also stocks the others lets you standardise on one source while matching each product to its condition.

Regulatory Background Buyers Should Know

The EU restricted phosphates in consumer laundry detergents and banned them in dishwasher tablets from 2017. EDTA, meanwhile, appears on many retailer restricted-substance lists because it resists degradation. GLDA-Na4 answers both pressures at once, which is why it features in reformulation plans across the cleaning industry.

GLDA-Na4 in Textile, Pulp and Metal Cleaning

Textile mills use GLDA-Na4 to keep dye baths consistent and to stabilise peroxide during bleaching. 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 case, the biodegradable profile reduces the load on effluent treatment.

How a GLDA-Na4 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.

Storage and Handling

GLDA-Na4 is a liquid chelant supplied in drums or IBCs. Store it in a cool, dry place away from strong acids, and observe the shelf life stated on the SDS. Because it is alkaline, avoid contact with skin and eyes and follow the handling guidance in the safety data sheet.

Certificates and Samples from a GLDA-Na4 Supplier

Every shipment includes a Certificate of Analysis, and TDS and SDS files are available on request. Starting a project is simple: tell us your current chelator, target application, and required volume. We return a recommendation, a quotation, and a sample for evaluation.

Frequently Asked Questions

How do I replace EDTA with GLDA-Na4?

Replacement depends on your pH, target metal ions, and dosage. We review your formula and propose a starting ratio, then you confirm it through bench and field tests.

Do you provide REACH registration support?

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.
