EDTA Na4
General Information
Ethylenediaminetetraacetic acid tetrasodium salt (EDTA Na4) is a white crystalline powder that is soluble in water. It is odorless, tasteless and a powerful chelating agent. EDTA Na4 can be used as a food additive to prevent spoilage and food discoloration. By binding metal ions, EDTA Na4 reduces oxidative degradation and discoloration caused by metals in foods.
Additionally, EDTA Na4 has widespread industrial applications. It serves as a water treatment agent to remove metal ions and hardness from water. As an additive in detergents, EDTA Na4 enhances cleaning capability by sequestering metals. In the paper industry, EDTA Na4 prevents metal-induced degradation and discoloration. It is also used in cosmetics and pharmaceuticals for stability.
In, agriculture, the EDTA Na4 can be used in trace elements fertilizer industry, to promote crops health level and increase yield.
