Description

Edta Dipotassium Magnesium Salt, Dihydrate is a stable, water-soluble chelating agent complex of magnesium and the dipotassium salt of ethylenediaminetetraacetic acid (EDTA). This compound is valued for its ability to effectively sequester di- and trivalent metal ions in aqueous systems, preventing undesirable precipitation and catalytic activity. It is essential for manufacturers and formulators in industries such as pharmaceuticals, personal care, and analytical chemistry where precise metal ion control is critical for product stability and performance.

Application

• Pharmaceutical Formulations: Used as a stabilizing agent in injectables, ophthalmics, and topical products to chelate trace metals that can catalyze degradation.
• Personal Care & Cosmetics: Acts as a chelator in shampoos, creams, and lotions to enhance shelf life by inactivating metal ions that can cause rancidity or color change.
• Analytical Chemistry: Serves as a standard or reagent in complexometric titrations and as a buffer component in various biochemical assays.
• Industrial Processes: Employed in water treatment, textile processing, and cleaning formulations to control water hardness and improve process efficiency.
• Agriculture: Can be used in micronutrient fertilizer formulations to improve the bioavailability of essential metals to plants.

Quality Control

Our Edta Dipotassium Magnesium Salt, Dihydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. We provide Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, heavy metal content, and loss on drying. Our quality commitment supports applications requiring high standards, including pharmaceutical and cosmetic GMP guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or changes in assay.
