GLDA: The Truly Green EDTA Alternative. Factory Direct.

For decades, EDTA (Ethylenediaminetetraacetic Acid) and HEDP (Hydroxyethylidene Diphosphonic Acid) dominated industrial chelation. Yet growing regulatory pressure and sustainability demands expose their critical flaws:

❌ The Hidden Costs of Traditional Chelators

1. EDTA:

   • Non-Biodegradable: Persists in ecosystems, accumulates in waterways (EU REACH SVHC-listed).

   • Toxicity Risks: Remobilizes heavy metals, disrupting wastewater treatment.

   • Banned in Eco-Certifications: Non-compliant with EU Ecolabel, Nordic Swan.

2. HEDP:

   • Phosphorus Content: Contributes to eutrophication; restricted in detergents globally (e.g., US, EU phosphate bans).

   • Stability Issues: Degrades in high-temperature/oxidizing environments.

   • Slow Biodegradation: Fails OECD 301 standards (>28 days).

Result? Formulators face reformulation headaches, compliance risks, and brand reputational damage.

✅ GLDA: The High-Performance, Planet-Safe Solution

Tetrasodium Glutamate Diacetate (GLDA) isn’t just an alternative—it’s an upgrade. Sourced from renewable L-glutamic acid, GLDA delivers:

• Superior Biodegradability: Readily biodegradable (>60% in 28 days per OECD 301F), minimizing environmental persistence and complying with the strictest international eco-label standards (EU Ecolabel, Nordic Swan).

• Powerful Chelation Performance: Offers excellent stability constants across a wide pH range, often matching or exceeding the performance of EDTA, especially in challenging alkaline conditions.

• Eco-Toxicity Advantage: Demonstrates a favorable environmental profile with low aquatic toxicity and no contribution to eutrophication (phosphorus-free).

• Enhanced Stability: Maintains efficacy in high-temperature and oxidizing environments, ensuring consistent performance in applications like industrial cleaning and water treatment.

• Renewable & Plant-Based: Derived from sustainable feedstocks, reducing reliance on petrochemicals and aligning with circular economy principles.

• Regulatory Compliance: Easily meet and exceed current and anticipated global restrictions on persistent chelants.

• Brand Protection & Enhancement: Showcase your commitment to sustainability with a proven, eco-preferred ingredient, strengthening consumer trust and brand value.

• Uncompromised Performance: Guarantee product efficacy without sacrificing cleaning power, scale inhibition, or stability.
