Description

Ethylenediaminetetraacetic Acid Disodium Zinc Salt is a stable, water-soluble metal chelate of EDTA, specifically designed to provide bioavailable zinc in a controlled and safe manner. This compound is critical for applications requiring a highly effective, non-reactive zinc source that prevents precipitation and unwanted interactions in complex formulations. It is essential for manufacturers in the personal care, nutraceutical, and industrial stabilization sectors who require a consistent and high-purity ingredient.

Application

• Personal Care & Cosmetics: Acts as a stabilizing agent and controlled zinc source in anti-dandruff shampoos, deodorants, and skin care products to enhance efficacy and shelf-life.
• Nutraceuticals & Dietary Supplements: Used as a zinc fortifier in mineral supplements and functional foods due to its superior bioavailability and stability compared to inorganic zinc salts.
• Industrial Processes & Stabilization: Serves as a metal ion sequestrant in chemical synthesis, textile processing, and polymer production to prevent catalytic degradation and discoloration.
• Agriculture & Animal Nutrition: Employed in micronutrient fertilizers and animal feed premixes to provide chelated zinc, improving plant uptake and animal absorption.
• Laboratory & Analytical Reagents: Utilized in buffer solutions and as a standard in complexometric titrations for the determination of various metal ions.
