Description

Calcium Disodium Edta is a high-purity chelating agent widely recognized for its exceptional ability to sequester di- and trivalent metal ions. This property is critical for stabilizing formulations, preventing oxidation, and enhancing product shelf-life across numerous industries. It is an essential ingredient for manufacturers in the food, pharmaceutical, cosmetic, and industrial sectors seeking reliable and compliant raw materials.

Application

• Food & Beverage Industry: Used as a preservative and stabilizer to control metal-catalyzed oxidation, maintaining color and flavor in canned goods, dressings, and soft drinks.
• Pharmaceuticals: Employed as a stabilizing agent in injectable solutions, ophthalmic preparations, and topical products to chelate trace metals that can degrade active ingredients.
• Cosmetics & Personal Care: Acts as a sequestrant in creams, lotions, and shampoos to improve stability and prevent rancidity caused by metal impurities in water or other ingredients.
• Industrial Cleaning: A key component in detergent formulations and boiler water treatment solutions to control water hardness by binding calcium and magnesium ions.
• Agriculture: Used in micronutrient fertilizers and as a chelating agent in agricultural sprays to enhance the bioavailability of essential metals to plants.
• Laboratory & Analytical Chemistry: Serves as a standard and complexometric titrant in analytical procedures for determining metal ion concentrations.
