Description

Ethylenediaminetetraacetic Acid, Disodium Zinc Salt is a stable, water-soluble metal chelating agent, specifically the zinc complex of EDTA. This compound is valued for its ability to sequester metal ions, offering enhanced stability and functionality compared to the free acid or other EDTA salts in specific applications. It is primarily utilized in industries such as personal care, agriculture, and industrial cleaning where controlled metal chelation is required.

Application

• Personal Care & Cosmetics: Acts as a stabilizer and chelating agent in shampoos, creams, and lotions to inactivate metal ions that can degrade product quality.
• Agricultural Formulations: Used in micronutrient fertilizers and agrochemicals to improve the bioavailability and stability of zinc and other essential metals.
• Industrial Cleaning: Incorporated into detergent and cleaning formulations to control water hardness and prevent scale formation.
• Chemical Synthesis & Catalysis: Serves as a ligand or metal source in various chemical processes and catalytic reactions.
• Water Treatment: Employed to control metal ion concentrations in specific industrial water systems.
• Laboratory & Analytical Reagent: Used as a standard or complexing agent in analytical chemistry and research.
