Description

Edta CAS NO 60-00-4 is a high-purity chelating agent, chemically known as ethylenediaminetetraacetic acid. This versatile compound is essential for binding and sequestering di- and trivalent metal ions in aqueous solutions, preventing unwanted precipitation and catalytic activity. It is a critical raw material for industries requiring precise metal ion control, including pharmaceuticals, food & beverage, personal care, and industrial water treatment.

Application

• Pharmaceuticals & Cosmetics: Used as a stabilizer in formulations to chelate trace metals that can catalyze oxidation and degrade active ingredients; also used in ophthalmic solutions and as a preservative enhancer.
• Food & Beverage Industry: Employed as a sequestrant (INS 385) to preserve color, flavor, and texture by preventing metal-catalyzed oxidation and rancidity in products like mayonnaise, canned seafood, and soft drinks.
• Industrial Cleaning & Detergents: A key component in cleaning formulations, boiler descaling agents, and soaps to soften water by binding calcium and magnesium ions, thereby improving cleaning efficiency.
• Agrochemicals & Micronutrient Fertilizers: Acts as a chelating agent in micronutrient fertilizers (e.g., Fe-EDTA) to enhance plant uptake of essential metals and in pesticide formulations to improve stability.
• Laboratory & Analytical Chemistry: Serves as a primary standard in complexometric titrations (e.g., water hardness testing) and as a buffer component in biochemical and molecular biology applications.
• Pulp & Paper and Textile Processing: Used to control metal ions during bleaching processes to prevent decomposition of bleaching agents and to improve the brightness and quality of the final product.

Quality Control

Our Edta is manufactured under a strict quality management system. We offer various grades, including Technical, USP, and FCC, each produced to meet precise specifications. Every batch undergoes rigorous analytical testing, including assay, heavy metals, and residue on ignition, to ensure consistent purity and performance. Certificates of Analysis (COA) compliant with relevant pharmacopeial standards (USP/EP) or food chemical codes (FCC) are available upon request.

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). 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 and reduced efficacy.
