Description

Ethylenediaminetetraacetic Acid, Calcium Salt is a stable, water-soluble chelating agent widely used to sequester metal ions. This compound is valued for its ability to bind and deactivate problematic divalent and trivalent cations, thereby preventing undesired reactions and precipitation in complex formulations. It serves as a critical ingredient for manufacturers in the pharmaceutical, food, and personal care industries, where precise control over metal ion activity is required for product stability and efficacy.

Application

• Pharmaceutical Formulations: Used as a stabilizing agent in injectables, ophthalmics, and topical products to chelate trace metals that can catalyze degradation.
• Food & Beverage Additive: Functions as a preservative and sequestrant to maintain color, flavor, and shelf-life by inhibiting metal-catalyzed oxidation.
• Cosmetics & Personal Care: Employed in creams, lotions, and shampoos to enhance stability and prevent rancidity by chelating impurities.
• Industrial Cleaning & Boiler Treatment: Acts as a scale inhibitor and dispersant in water treatment and cleaning formulations by binding calcium and magnesium ions.
• Laboratory & Analytical Reagent: Serves as a standard and complexometric titrant in analytical chemistry for the determination of various metal ions.
• Agricultural Chemicals: Used in certain fertilizer and pesticide formulations to improve nutrient availability and compatibility.

Quality Control

We supply Ethylenediaminetetraacetic Acid, Calcium Salt in various grades, including Technical, Food (FCC), and Pharmaceutical (USP/EP) standards. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) documenting purity, identity, and specific impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
