Trilium (EDTA)
Trilium EDTA is a high-purity, versatile chelating agent known chemically as ethylenediaminetetraacetic acid (EDTA) or its trisodium salt form. It is widely used across industries to bind and sequester metal ions, improving product stability and performance. Trilium EDTA effectively prevents metal ion contamination, controls hardness in water, enhances cleaning efficiency, and stabilizes formulations in pharmaceuticals, cosmetics, agriculture, and industrial applications. Its strong chelating properties make it an essential ingredient for complexation and metal ion control.
Trilium (EDTA)
