Description

Edta Calcium Disodium is a high-purity chelating agent, also known as calcium disodium edetate. This compound is essential for its powerful ability to sequester and deactivate metal ions, preventing unwanted reactions and degradation. It is a critical raw material for manufacturers in the pharmaceutical, food, and industrial sectors who require reliable metal ion control for product stability and safety.

Application

• Pharmaceutical Formulations: Used as a stabilizing agent in injectables, ophthalmic solutions, and topical products to chelate trace metals that can catalyze oxidation.
• Food Additive (INS 385): Acts as a preservative and sequestrant in canned foods, dressings, and beverages to maintain color, flavor, and shelf-life.
• Heavy Metal Detoxification: The active pharmaceutical ingredient (API) in chelation therapy for treating lead, cadmium, or other heavy metal poisoning.
• Cosmetics & Personal Care: Employed in creams and lotions as a stabilizer to protect active ingredients from metal-catalyzed breakdown.
• Industrial Processes: Used in water treatment, textile processing, and pulp & paper manufacturing to control water hardness and metal ion interference.
• Laboratory & Analytical Reagent: Serves as a key component in buffer solutions, titrants, and metal ion masking agents in various chemical analyses.

Quality Control

Our Edta Calcium Disodium is manufactured under strict quality management systems. We offer grades compliant with major pharmacopoeial standards including USP, EP, BP, and JP, as well as FCC for food applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. Comprehensive Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture which can lead to caking or degradation.
