Dissolvine GL is the tetrasodium salt of glutamic acid oxalate (GLDA-NA4), which can bind the nitrogen atom in the center of the molecular structure with the second and third order metal ions through strong multiple bonds. Dissolvine GL-47-S is tetrasodium glutamate oxalate (GLDA-NA4). GLDA has four carboxylic acid groups, which can combine the nitrogen atom in the center of the molecular structure with divalent and trivalent metal ions. The multiple bonds are bonded. Dissolvine GL-47-S is made from food-grade natural amino acid salt L-Glutamate (MSG). Using this bio-based raw material can pillow more than half of the carbon in GLDA is bio-based. The natural amino acid structure in the Dissolvine GL-47-S molecule makes it easily recognized as food by bacteria, making GLDA easy to biodegrade. Dissolvine GL-47-S is a strong chelating agent for hard water metal ions (such as Ca²⁺), which can enhance the softening, cleaning ability and stability of the detergent formulation.
