CAS No.: 51981-21-6
<\/strong>Chemical formula: C8H7NO8.4Na;
Chemical Name:
Tetrasodium glutamate diacetate;
Tetrasodium N,N-bis(carboxylatomethyl)-L-glutamate;
L-Glutamic acid, N,N-bis(carboxymethyl)-, sodium salt (1:4);<\/p>\n\n\n\n

GLDA is an environmentally friendly chelating agent, biodegradable, phosphorus-free and cyanide-free.
GLDA can replace traditional complexing agents such as organophosphorus, EDTA and NTA within a certain range.
Other metal salts such as GLDA potassium salt can be customized.<\/p>\n\n\n\n

Features:<\/strong><\/p>\n\n\n\n

    \n
  1. Form water-soluble complexes with various metal ions in a wide pH range. High solubility in acidic and alkaline solutions.<\/li>\n\n\n\n
  2. High temperature resistance, long-term high temperature environment can also maintain stable performance.<\/li>\n\n\n\n
  3. 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.<\/li>\n<\/ol>\n\n\n\n

    Technical Data:
