功效 / Functions

谷氨酸二乙酸四钠（GLDA·Na4）具有较强的螯合金属的能力，是新一代生物可降解绿色螯合剂。

N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) has a strong ability to chelate metals and is a new generation of biodegradable green chelating agent.

N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) can bind the nitrogen atom in the center of the molecular structure with the secondary and tertiary metal ions through strong multiple bonds.

N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) has four carboxylic acid groups, which can bind the nitrogen atom in the center of the molecular structure with the secondary and tertiary metal ions through strong multiple bonds.

N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) is made from food-grade natural amino acid salt sodium L-glutamate (MSG). The use of this bio-based raw material ensures that more than half of the carbon in N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) is bio-based.

The natural amino acid structure in the N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) molecule makes it easily recognized as food by bacteria, making GLDA easily biodegradable.

N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) is a strong chelator for hard water metal ions (such as Ca2+), which can enhance the softening, cleaning ability and stability of detergent formulations.

N,N-Bis(Carboxymethyl)-L-Glutamic Acid Tetrasodium Salt (GLDA·Na4) has strong compatibility and stability with most enzyme preparations.
