Description

Ethylenediaminetetraacetic Acid Calcium Disodium Salt Hydrate is a water-soluble, stable chelating agent widely used to sequester di- and trivalent metal ions. Its primary commercial value lies in its ability to inactivate metal ions that can catalyze oxidation, cause discoloration, or reduce stability in various formulations. This compound is essential for manufacturers in the pharmaceutical, food & beverage, and personal care industries seeking to enhance product shelf-life and purity. It is also a critical reagent in clinical diagnostics and laboratory analysis.

Application

• Pharmaceutical Formulations: Used as a stabilizer and chelating agent in injectables, ophthalmics, and topical products to bind trace metals.
• Food & Beverage Additive (as Calcium Disodium EDTA): Serves as a preservative and color/ flavor stabilizer in canned goods, dressings, and soft drinks.
• Personal Care & Cosmetics: Acts as a sequestrant in shampoos, soaps, and lotions to improve clarity and prevent rancidity.
• Clinical & Diagnostic Reagents: Employed in blood collection tubes (e.g., as an anticoagulant) and in various diagnostic assay kits.
• Industrial Cleaning & Water Treatment: Used in cleaning formulations and boiler water treatment to control scale and metal ion interference.
• Laboratory Research: A standard chelator in biochemical and molecular biology buffers to inhibit metalloenzymes.

Quality Control

Our Ethylenediaminetetraacetic Acid Calcium Disodium Salt Hydrate is produced under a strict quality management system. We offer grades compliant with relevant pharmacopeial standards such as USP, EP, and BP, as well as food-grade specifications (FCC). Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting purity, heavy metals, and other critical parameters are available upon request to ensure full traceability and compliance for your application.

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 reduced stability.
