Description

Ethylenediaminetetraacetic Acid, Zinc Salt is a coordination compound formed from the chelating agent EDTA and zinc ions. This product is valued for its ability to provide a stable, bioavailable source of zinc while also functioning as a powerful chelating agent to control metal ion activity. It is essential for industries requiring precise metal ion stabilization, nutrient delivery, or sequestration in complex formulations. Key sectors include personal care, agriculture, and industrial water treatment.

Application

• Personal Care & Cosmetics: Acts as a chelating agent in shampoos, creams, and lotions to enhance product stability by sequestering metal ions that can cause rancidity or discoloration. Also serves as a source of zinc for anti-dandruff and skin-soothing formulations.
• Agricultural Micronutrient Fertilizers: Used in chelated micronutrient fertilizers to provide highly bioavailable zinc to plants, correcting deficiencies and improving crop yield and quality in a form stable across a wide pH range.
• Industrial Water Treatment: Employed as a scale and corrosion inhibitor in cooling water and boiler systems by chelating calcium, magnesium, and other metal ions that contribute to scale formation.
• Pharmaceutical & Nutritional Supplements: Functions as a stabilizing agent in certain pharmaceutical preparations and as a source of zinc in mineral supplements, leveraging its high stability and bioavailability.
• Chemical Synthesis & Catalysis: Serves as a ligand or metal ion buffer in various chemical processes and catalytic reactions where controlled zinc ion concentration is critical.
• Laboratory & Analytical Reagents: Used in analytical chemistry as a complexometric titrant and in buffer solutions for standardizing EDTA titrations and studying metal ion interactions.
