Description

Sodium Edetate is the disodium salt of ethylenediaminetetraacetic acid (EDTA), a powerful and versatile chelating agent. Its primary value lies in its exceptional ability to bind and sequester di- and trivalent metal ions, effectively controlling unwanted metal-catalyzed reactions and precipitation. This makes it an essential component for manufacturers in the pharmaceutical, cosmetic, food, and industrial cleaning sectors who require precise control over product stability, clarity, and shelf-life.

Application

• Pharmaceutical Formulations: Used as a stabilizer in injectables, ophthalmic solutions, and topical products to chelate trace metals that can catalyze oxidation and degrade active ingredients.
• Cosmetics & Personal Care: Acts as a preservative booster and chelator in shampoos, creams, and lotions to enhance formula stability and prevent discoloration caused by metal impurities.
• Food & Beverage Industry: Employed as a sequestrant (INS 386) to preserve color, flavor, and texture by inhibiting metal-catalyzed oxidation and enzymatic browning.
• Industrial Cleaning & Boiler Treatment: Key ingredient in detergents and descaling agents to bind calcium and magnesium ions, preventing scale formation and improving cleaning efficiency.
• Laboratory & Analytical Chemistry: Serves as a critical component in buffer solutions, titrants, and as a masking agent in complexometric titrations and various analytical procedures.
• Textile & Pulp Processing: Utilized to control metal ions in dyeing processes and pulp bleaching, improving color fastness and process efficiency.

Quality Control

We supply Sodium Edetate that meets stringent quality standards, including USP-NF, Ph. Eur., BP, and FCC grades for applications requiring the highest purity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing parameters such as assay, heavy metals, and clarity of solution.

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 and reduced efficacy.
