GLDA 47% liquid

Identity

Key Benefits

  • Derived from natural, bio-based raw materials
  • Effective across a broad pH range with excellent

performance in mildly acidic through strongly

alkaline systems.

  • Excellent solubility in water
  • Excellent thermal stability under normal

formulation and industrial processing conditions.

  • Readily biodegradable and environmentally friendly
  • Improves cleaning and formulation performance
  • Compatible with surfactants and oxidizing systems.
  • Strong chelation of Ca, Mg, Fe, Mn, Zn and Cu.
  • Enables phosphate-free formulations

Physical & Chemical Properties

GLDA 47% appears as a slightly

yellow, transparent liquid with

excellent water solubility. It remains

stable in both acidic and alkaline

environments, making it highly

versatile in formulation.

Typical properties and specifications

Typical Properties:

  • Active Content: ≥ 47%
  • pH (1% solution): 11.0–12.0
  • Appearance: Slightly yellow transparent liquid
  • NTA: ≤ 0.1%

Its high solubility allows formulation of concentrated systems,

even at low pH, where many traditional chelants fail.

Product Overview

GLDA 47% Liquid (tetrasodium glutamate diacetate) is a next-generation, biodegradable chelating agent

designed to deliver high performance across a wide pH range. Derived from natural amino acids, GLDA

combines strong metal binding capability with an excellent environmental profile, making it a preferred

alternative to traditional chelants such as EDTA and NTA. It is highly soluble, stable in both acidic and

alkaline systems, and enables superior formulation flexibility across cleaning, agriculture, and industrial

applications.

Chemical Identity

GLDA (L-glutamic acid N,N-diacetic acid, tetrasodium salt) is

a tetrafunctional aminopolycarboxylate chelating agent.

  • CAS Number: 51981-21-6
  • Molecular Formula: C9H9NO8Na4
  • Molecular Weight: 351.1 g/mol

Applications and benefits

Its structure contains four carboxylate groups and one nitrogen

center, allowing it to form stable complexes with both divalent

and trivalent metal ions.
