Description

Edta Dimagnesium Salt is a high-purity chelating agent and a stable magnesium source, essential for applications requiring precise metal ion control. Its primary value lies in its ability to form stable, water-soluble complexes with a wide range of metal ions, preventing unwanted precipitation and catalytic activity. This makes it a critical component for manufacturers in the pharmaceutical, food & beverage, and personal care industries seeking consistent quality and performance.

Application

• Pharmaceutical Formulations: Used as a stabilizer and magnesium source in injectable solutions, tablets, and nutritional supplements to enhance shelf-life and bioavailability.
• Food & Beverage Additive: Functions as a sequestrant and stabilizer to control metal-catalyzed oxidation, preserving color, flavor, and texture in processed foods and beverages.
• Personal Care & Cosmetics: Acts as a chelating agent in creams, lotions, and shampoos to improve product stability by inactivating metal impurities that can cause rancidity or formula breakdown.
• Industrial Water Treatment: Employed in boiler and cooling water systems to sequester scale-forming cations like calcium and iron, preventing corrosion and fouling.
• Laboratory & Analytical Reagent: Serves as a standard and complexing agent in titrations, buffer solutions, and molecular biology applications.
• Agriculture & Horticulture: Used in micronutrient fertilizers and foliar sprays to deliver bioavailable magnesium in a chelated form, preventing nutrient lock-up in soil.

Quality Control

Our Edta Dimagnesium Salt is manufactured under a strict quality management system. Production adheres to cGMP principles, and the material is suitable for applications requiring compliance with USP-NF, FCC, and Ph. Eur. monographs where applicable. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles to ensure it meets your specific grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent absorption of atmospheric moisture, which can lead to caking or reduced stability.
