Description

Dipotassium Edta CAS NO 2001-94-7 is the dipotassium salt of ethylenediaminetetraacetic acid (EDTA), a powerful chelating agent widely used to sequester di- and trivalent metal ions. This compound is critical for stabilizing formulations and preventing unwanted metal-catalyzed degradation across numerous industries. It is an essential raw material for manufacturers in the pharmaceutical, cosmetic, personal care, and food processing sectors who require reliable, high-purity chelating agents.

Application

• Pharmaceutical Formulations: Used as a stabilizer in injectables, ophthalmic solutions, and topical products to chelate trace metals that can catalyze oxidation and reduce shelf life.
• Cosmetics & Personal Care: Acts as a preservative booster and sequestrant in shampoos, creams, and lotions to enhance stability and prevent discoloration.
• Food Additive: Employed as a sequestrant (INS 452) to preserve color, flavor, and texture in processed foods, beverages, and canned products.
• Laboratory & Analytical Reagents: Serves as a key component in buffer solutions, titrants, and metal ion masking agents for complexometric titrations and biological assays.
• Industrial Cleaning & Boiler Treatment: Utilized in cleaning formulations and water treatment to control scale formation by sequestering calcium and magnesium ions.
• Textile & Pulp Processing: Helps in bleaching and dyeing processes by deactivating metal impurities that can interfere with chemical reactions.

Quality Control

Our Dipotassium EDTA is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for pharmaceutical, cosmetic, and food-grade applications. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters 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 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.
