GLDA: The Biodegradable Powerhouse Revolutionizing EDTA Applications

For decades, Ethylenediaminetetraacetic acid (EDTA) has been the industry standard for chelation across numerous sectors. Its strong metal-binding capabilities made it indispensable in everything from industrial cleaning and water treatment to personal care and agriculture. However, growing environmental concerns have revealed critical limitations: EDTA's persistent nature leads to accumulation in waterways, where it can remobilize heavy metals and resist degradation for years.

Enter Tetrasodium Glutamate Diacetate (GLDA) – the high-performance, readily biodegradable alternative that matches or exceeds EDTA's technical capabilities while addressing its environmental drawbacks. Derived from fermented natural amino acids, GLDA represents a paradigm shift in sustainable chelation technology.

Why GLDA Outperforms EDTA

• Superior Environmental Profile: GLDA is readily biodegradable (>60% in 28 days per OECD 301B), breaking down into harmless substances instead of persisting in ecosystems like EDTA.

• Exceptional Chelation Power: Demonstrates excellent stability constants for calcium, magnesium, and heavy metals across a wide pH range (3-13), often outperforming EDTA in challenging formulations.

• Renewable & Sustainable: Produced from plant-based feedstocks, GLDA offers a reduced carbon footprint compared to petrochemical-derived EDTA.

• Regulatory Compliance: GLDA is listed on the EPA Safer Chemical Ingredients List (SCIL) and complies with stringent international regulations including EU REACH and ZDHC MRSL, future-proofing your formulations.

Application-Specific Advantages:

• Cleaning & Detergents: Enhances cleaning efficiency in hard surface cleaners, laundry detergents, and automatic dishwashing formulas while meeting eco-label requirements.

• Water Treatment: Provides effective scale inhibition and metal ion control in cooling water, boiler systems, and RO membranes without environmental persistence.

• Personal Care: Serves as a gentle yet effective stabilizer in shampoos, body washes, and cosmetics, replacing EDTA while maintaining product integrity.

• Agriculture & Textiles: Acts as an efficient micronutrient carrier in fertilizers and improves dyeing processes without accumulating in soil or wastewater.
