Features of GLDA-Na4

GLDA has excellent solubility across a broad pH range, making it an ideal option for formulating high-potency products with low water content. When exposed to high temperatures, GLDA remains stable and shows no signs of decomposition – outperforming other chelating agents tested under the same conditions. In addition, GLDA has a strong chelation ability that makes it effective against calcium scales and other hard-to-remove debris from equipment. Its natural amino acid components also make it an ideal antiseptic and synergistic agent; studies have shown that it can reduce fungicide usage by up to 80%.
