GLDA is an environmentally friendly chelating agent (also known as sequestering and complexing agent), biodegradable, phosphorus-free.
GLDA is biodegradable, phosphorus-free, and more environmentally friendly.
The main raw material of GLDA is MSG (monosodium glutamate), which is of natural origin.
GLDA can replace traditional complexing agents such as organophosphorus, EDTA and NTA within a certain range.
Features:
- Form water-soluble complexes with various metal ions in a wide pH range, high solubility in acidic and alkaline solutions.
Unlike many aminopolycarboxylic acids which are unstable in acidic environments, GLDA can exist stably in acidic environments and chelate iron ions.
Under alkaline conditions, GLDA is widely used as an aminopolycarboxylic acid and can well chelate calcium and other metal ions. - High temperature resistance, long-term high temperature environment can also maintain stable performance.
- It has the effect of sterilization and antiseptic efficiency, preventing the formulation or process liquid from discoloration and odor. Contains amino acid chelating agent, easier to combine with the cell wall, destroy the bacteria, improve the effect of the use of bactericides.
Technical Data:
Appearance: colorless to light yellow liquid, aqueous solution;
pH: 11±1 (solution, 25°C);
Density: 1.30~1.50 (solution, 25°C);
Specifications are subject to change without prior notice.
Applications:
GLDA is mainly used as a chelating agent and can be adapted to most traditional chelating agent application scenarios.
Scale inhibitors and descalers, industrial cleaning agents, household detergents, hydrogen peroxide bleach stabilizers (e.g. pulp and paper making, textile bleaching), textiles auxiliaries (metal ion shielding/sequestering agent), metal surface treatment, gas sweetening/desulfurization (iron ion carriers), oilfield chemicals, car cleaning agents, agriculture, etc.
Traditonal Chelating Agents:
Aminopolycarboxylates: EDTA, EDTA-Na, DTPA & DTPA-5Na
Polyphosphonates: HEDP, DTPMP, ATMP
