What is Tetrasodium Glutamate Diacetate (GLDA 4Na)?
Tetrasodium Glutamate Diacetate (GLDA 4Na) is a readily biodegradable, bio-based chelating agent (CAS No. 51981-21-6) engineered to bind metal ions such as calcium, magnesium, and iron in high-performance industrial formulations. As a non-sensitizing and sustainable EDTA alternative, it provides a phosphorus-free solution for detergents, industrial cleaning, and water treatment, ensuring compliance with the strictest global environmental standards.

In simple terms, GLDA 4Na works like a “metal ion trap.” It locks hardness ions in water so that cleaning agents, surfactants, and additives can perform consistently—regardless of water quality.
GLDA 4Na Technical Specifications
For technical procurement and chemical engineers, the following High Stability Constant parameters are critical for formulation integrity:
| Parameter | Typical Value | Industry Significance |
| Appearance | Light yellow liquid | Formulation clarity |
| Assay (%) | ≥ 47 | Active concentration efficiency |
| pH (1% solution) | 11–12 | Compatibility in alkaline systems |
| Density (20°C) | ~1.3 g/cm³ | Accurate dosing & logistics |
| Iron (Fe) content | ≤ 10 ppm | High purity for sensitive apps |
| Solubility | Fully miscible | Stability in liquid concentrates |
Key Functional Benefits & Strong Sequestration Power
Manufacturers switch to GLDA 4Na from HOOCHEMTEC because of its reliable performance under rigorous industrial conditions:
- Strong Sequestration Power: It effectively controls Ca2+ and Mg2+ even at stoichiometric ratios, preventing mineral interference.
- High Stability Constant: Unlike some bio-based alternatives, GLDA 4Na maintains a high stability constant across a wide pH range (2–13), ensuring long-term shelf life for formulated products.
- Phosphorus-Free & NTA-Free: Ideal for formulations targeting EU Ecolabel, Nordic Swan, or US EPA Safer Choice certifications.
- Non-Sensitizing Profile: Its mild nature and low toxicity make it the preferred green chelating agent for personal care and “green” home care brands.
Compared to traditional agents, GLDA 4Na also functions as a biodegradable chelating agent, making it suitable for environmentally sensitive formulations.
In practice, this means fewer formulation failures and more consistent cleaning results—especially in hard water regions.
GLDA 4Na Applications in Cleaning, Detergents & Water Treatment
GLDA 4Na is widely used across multiple industrial sectors

1. Industrial Cleaning (CIP & Heavy-Duty)
Essential for CIP (Cleaning-in-Place) systems in beverage plants. Its high temperature stability ensures scale-free pipes and optimized hygiene.
2. Detergents & Home Care
Enables phosphorus-free liquid laundry and dishwashing products. It improves stain removal by deactivating hard water minerals that interfere with surfactants.
3. Water Treatment Chemicals
Acts as a high-performance scale inhibitor in cooling towers and heat exchangers, maintaining operational uptime and reducing chemical descaling frequency.
4. Agriculture & Micronutrient Delivery
Chelates trace metals in liquid fertilizers, ensuring that micronutrients remain bio-available for crop uptake in high-pH or alkaline soils.
Pro Tip for Sourcing: As a factory-exporter, we recommend shipping GLDA 4Na in IBC Totes to maximize container utilization and reduce unit logistics costs by up to 15%.
GLDA vs EDTA: A Practical Replacement Guide for Buyers
For many buyers, the real question is: Should I switch from EDTA to GLDA?
| Factor | GLDA 4Na (Green Choice) | EDTA (Traditional) |
| Biodegradability | Readily Biodegradable | Poor / Persistent |
| Regulatory Risk | Low (REACH Compliant) | High (Increasing Restrictions) |
| Ecological Profile | Phosphorus-Free / Non-Toxic | Potential Bioaccumulation |
| Stability Constant | High & Reliable | Very Strong |
Strategic Advice: For brands exporting to Europe or North America, transitioning to GLDA 4Na is no longer optional—it is a regulatory necessity to avoid "non-biodegradable" labeling.
GLDA 4Na Sourcing Guide: Price, MOQ & Supplier Selection
1. What Impacts GLDA 4Na Pricing?
- Order volume (bulk vs small batch)
- Packaging type (drums, IBC, bulk tanker)
- Export destination and freight cost
- Raw material fluctuations
2. Typical MOQ for Bulk Buyers
| Packaging Type | MOQ Range |
|---|---|
| 250kg Drums | 1–4 pallets |
| 1250kg IBC | 1–2 units |
| Bulk Tanker | 20–25 MT |
3. Lead Time Expectations
- Standard production: 2–4 weeks
- Repeat orders: more stable and predictable
4. B2B Cost Optimization Tips
- Consolidate into full container loads
- Choose IBC over drums for logistics efficiency
- Work with factory-direct suppliers to reduce costs
Compliance, Sustainability & Market Trends
Global regulations are pushing industries toward green chelating agents:
- EU REACH compliance requirements
- Detergent regulations limiting persistent chemicals
- Increasing restrictions on EDTA
GLDA 4Na meets these expectations as a bio-based sequestrant with strong biodegradability.
For exporters and distributors, this means:
- Easier market entry
- Lower regulatory risk
- Stronger positioning in eco-friendly product lines
