Description

Ethylenediaminetetraacetic Acid Dicalcium Salt is a highly effective chelating agent and sequestrant, specifically formulated as the calcium disodium salt of EDTA. This compound is critical for binding and inactivating di- and trivalent metal ions, thereby preventing unwanted oxidation, precipitation, and catalytic degradation in complex formulations. It is essential for manufacturers in the pharmaceutical, food, and industrial sectors requiring precise metal ion control to ensure product stability, safety, and performance.

Application

• Pharmaceutical Formulations: Used as a stabilizing agent in injectables, ophthalmics, and topical products to chelate trace metals that can catalyze drug degradation.
• Food & Beverage Additive (as Calcium Disodium EDTA): Functions as a preservative and sequestrant to maintain color, flavor, and shelf-life in canned goods, dressings, and soft drinks.
• Cosmetics & Personal Care: Employed in creams, lotions, and shampoos to enhance stability by chelating metal ions present in water or other ingredients.
• Industrial Cleaning & Descaling: A key component in cleaning formulations for boilers and heat exchangers to remove limescale and metallic deposits.
• Laboratory & Analytical Chemistry: Serves as a standard reagent in complexometric titrations and buffer solutions for metal ion analysis.
• Agriculture & Micronutrient Fertilizers: Used in chelated micronutrient formulations to improve plant availability and uptake of essential metals like iron and zinc.

Quality Control

Our Ethylenediaminetetraacetic Acid Dicalcium Salt is manufactured under a strict quality management system. Each batch is tested to ensure compliance with relevant pharmacopeial standards such as USP, EP, and food-grade specifications like FCC. A comprehensive Certificate of Analysis (COA) is provided for every shipment, detailing purity, assay, and limits for key impurities to guarantee batch-to-batch consistency and reliability for your critical applications.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture, which can lead to caking or reduced efficacy.
