Premium raw materials and specialized chemical agents manufactured to the highest international industry standards.
Modern industrial processing, cosmetic science, and cleaning formulation engineering face a unified challenge: replacing classical, environmentally persistent chelating agents with biodegradable alternatives without sacrificing performance. Tetrasodium Glutamate Diacetate (GLDA-Na4) has emerged as the definitive successor to EDTA (Ethylenediaminetetraacetic acid) and NTA (Nitrilotriacetic acid).
As a leading supplier in the daily chemical raw materials industry, Suzhou Yuantairun Chemical Co., Ltd. (YTR) delivers high-grade GLDA-Na4 globally. Synthesized primarily from L-glutamic acid—a natural, bio-based amino acid—GLDA-Na4 exhibits excellent ecological compatibility combined with superior sequestration capacity, making it a critical ingredient for eco-labeled household and industrial products.
Regulatory Dynamics: Global environmental agencies (including EPA, ECHA under REACH, and China’s MEE) are systematically restricting traditional, non-biodegradable synthetic aminopolycarboxylates (EDTA/phosphonates). Wholesale importers must transition to GLDA-Na4 to comply with modern eco-labeling standards.
Tetrasodium Glutamate Diacetate is a multi-dentate organic ligand capable of forming stable, water-soluble complexes with hard and transition metal ions, particularly Calcium (Ca2+), Magnesium (Mg2+), Iron (Fe3+), and Copper (Cu2+). This process, known as chelation, stabilizes products against oxidation, controls water hardness, and enhances surfactant efficacy.
GLDA-Na4 stands out for its rapid decomposition rate in the environment. Under standard OECD 301D testing guidelines, GLDA-Na4 achieves greater than 60% biodegradation within 28 days, categorizing it as "readily biodegradable." This prevents bioaccumulation in aquatic life and municipal waste streams, resolving the major environmental bottleneck associated with EDTA.
| Chelating Agent | Log K (Ca2+) | Log K (Mg2+) | Log K (Fe3+) | Biodegradability (28 Days) |
|---|---|---|---|---|
| GLDA-Na4 | 5.2 | 5.2 | 11.6 | > 60% (Readily Biodegradable) |
| EDTA-Na4 | 10.7 | 8.7 | 25.1 | < 10% (Persistent) |
| MGDA-Na3 | 7.0 | 5.8 | 16.5 | > 60% (Readily Biodegradable) |
| IDS-Na4 | 4.8 | 3.4 | 15.0 | > 80% (Readily Biodegradable) |
From large-scale industrial water purification to sensitive dermatology-grade cosmetics, Suzhou Yuantairun Chemical designs GLDA supply solutions optimized for specific product matrices.
In modern personal care formulations containing sensitive natural lipids, vitamins, and organic compounds, trace heavy metals catalyze rapid oxidation, causing discoloration, rancidity, and active component degradation. GLDA-Na4 stabilizes these matrices without irritating human skin. It is certified by EcoCert, COSMOS, and NPA, aligning with global green beauty initiatives.
In hard water conditions, calcium and magnesium ions form insoluble mineral precipitates that dull fabrics and leave spots on glassware. GLDA-Na4 acts as a builder, preventing scale formation and synergistically boosting the cleaning power of primary anionic surfactants, such as Sodium Lauroyl Sarcosinate and Sodium Cocoyl Alaninate.
Unlike EDTA, which has limited solubility in highly alkaline systems, GLDA-Na4 retains its high stability and binding capacity in extreme pH levels (from 2 up to 14) and at elevated temperatures. This makes it highly effective for industrial boiler descaling, vehicle cleaners, and metal surface treatments.
Exporters and factories must adhere to rigorous quality control frameworks to guarantee product uniformity across international borders. Suzhou Yuantairun Chemical operates with advanced chemical synthesis systems under strict compliance protocols.

Find answers to common questions about formulation compatibility, raw material sourcing, and stability properties.
While the raw material cost per metric ton for GLDA-Na4 can be higher than that of standard synthetic EDTA, it offers greater solubility and works synergistically with modern amino acid-based surfactants. Formulators can reduce the dosage of preservatives and secondary builders, making the overall formulation cost-competitive.
GLDA-Na4 liquid and powder have a shelf life of 24 months when stored in sealed, original packaging. Store them in a cool, dry, and well-ventilated warehouse, away from strong oxidizing acids, direct sunlight, and moisture.
