Product Overview

GLDA (Tetrasodium Glutamate Diacetate) is a next-generation, readily biodegradable chelating agent derived from fermented natural L-Glutamic acid. It sets a new standard for sustainable performance, offering superior metal ion control while addressing growing environmental and regulatory concerns associated with traditional chelators like EDTA.

This versatile, plant-based ingredient provides powerful sequestration across a wide range of applications, from demanding industrial cleaners to gentle personal care formulations. Our product is supplied as a light yellow viscous liquid for easy handling and integration.

Key Features & Benefits

• Superior Eco-Profile: Readily biodegradable (OECD 301D), made from renewable raw materials, and designed for minimal environmental impact.

• Exceptional Chelating Power: Demonstrates excellent stability constants for Ca²⁺, Mg²⁺, and Fe²⁺/³⁺ ions, even in high-temperature and alkaline conditions. Effective across a broad pH range.

• Outstanding Sustainability: An ideal, future-proof replacement for EDTA, NTA, and phosphates in green formulations.

• Excellent Compatibility & Safety: Works synergistically with surfactants, builders, and enzymes. Offers low irritation potential and is gentler on skin compared to many alternatives.

• Liquid Formulation: Supplied as an easy-to-use aqueous solution, simplifying dosing and processing.

Specifications

Specifications may vary slightly between batches. Please refer to the Certificate of Analysis for precise data.

Applications

GLDA is a versatile performer suitable for a multitude of industries:

• Cleaning & Detergents: Enhances performance in liquid laundry detergents, automatic dishwashing tabs, industrial & institutional (I&I) cleaners, and hard surface cleaners by controlling water hardness and stabilizing bleaches.

• Personal Care & Cosmetics: Used as a gentle yet effective chelator in shampoos, body washes, liquid soaps, and other rinse-off formulations to improve stability and clarity.

• Industrial Applications: Ideal for use in agrochemicals (as a carrier for micronutrients), textile processing, pulp & paper production, and metal treatment formulations.

• Water Treatment: Effective for scale inhibition and controlling metal ions in various water systems.

Packaging & Storage

• Packaging: Available in non-returnable HDPE plastic drums (25 kg, 220 kg / 55 gal) and IBC totes (1000 kg). Custom packaging options are available upon request.

• Storage & Handling: Store in a cool, dry, well-ventilated place in its sealed, original container. Keep away from strong acids and strong oxidizing agents. Protect from frost. The product has a shelf life of 24 months from the date of manufacture when stored under recommended conditions.

Safety & Handling

GLDA is an alkaline substance. Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, during handling. Avoid contact with skin, eyes, and clothing. In case of contact, flush immediately with plenty of water. For detailed safety information, please consult the Safety Data Sheet (SDS).
