Tetrasodium Glutamate Diacetate (GLDA) - The Sustainable Chelating Agent for European Markets

GLDA: The Future of Sustainable Chelation Technology

Tetrasodium Glutamate Diacetate (GLDA), registered under CAS number 51981-21-6, represents a significant advancement in sustainable chelation technology. As European industries increasingly prioritize environmental responsibility and regulatory compliance, GLDA emerges as the optimal solution for applications requiring effective metal ion control without ecological concerns.

Why GLDA Outperforms Traditional Chelators

• Superior Environmental Profile: Demonstrates rapid biodegradability (OECD 301) and is derived from renewable plant-based sources

• Enhanced Performance Characteristics: Excellent chelation stability across wide pH ranges (1-14) and temperature conditions

• Regulatory Compliance: Fully compliant with REACH, EU Ecolabel, and Cosmos standards

• Safety Advantages: Low ecotoxicity and minimal skin irritation potential

Comprehensive Application Portfolio

1. Detergents & Cleaning Products
GLDA significantly enhances cleaning performance in liquid detergents, automatic dishwashing formulations, and industrial cleaning products. Its exceptional calcium binding capacity (pCa 6.5 at pH 10) ensures superior stain removal and whiteness maintenance while meeting stringent EU ecological standards.

2. Personal Care & Cosmetics
As a gentle yet effective alternative to traditional preservative boosters, GLDA stabilizes formulations while maintaining compatibility with sensitive skin. Ideal for shampoos, skin care products, and color cosmetics requiring natural positioning.

3. Water Treatment Applications
GLDA effectively controls scale formation in cooling water systems, boilers, and reverse osmosis plants. Its thermal stability and corrosion inhibition properties make it suitable for demanding industrial water treatment applications.

4. Agricultural Formulations
Enhance micronutrient availability in fertilizer applications with GLDA's excellent chelation properties while ensuring environmental compatibility and soil health.
