Description

Ethylenediaminetetraacetic Acid Calcium Disodium Salt 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 unwanted catalytic reactions, and enhancing product shelf-life across diverse industries. It is an essential raw material for manufacturers in pharmaceuticals, food & beverage, cosmetics, and industrial water treatment who require reliable, consistent quality for their critical processes.

Application

• Pharmaceutical Formulations: Used as a stabilizing agent in injectables, ophthalmics, and topical products to chelate trace metals that can catalyze degradation.
• Food & Beverage Additive (as Calcium Disodium EDTA): Serves as a preservative and color/ flavor stabilizer in canned goods, dressings, and soft drinks.
• Cosmetics & Personal Care: Acts as a chelator in shampoos, creams, and lotions to improve stability and shelf life by inactivating metal impurities.
• Industrial Water Treatment: Effective in boiler and cooling water systems to control scale formation by sequestering calcium and magnesium ions.
• Laboratory & Analytical Chemistry: Employed as a key component in buffer solutions and titrants for complexometric titrations.
• Agriculture & Micronutrient Fertilizers: Used in chelated micronutrient formulations to enhance plant availability and uptake of essential metals like iron and zinc.

Quality Control

Our Ethylenediaminetetraacetic Acid Calcium Disodium Salt is manufactured under a strict quality management system. Each batch is tested to meet relevant specifications for USP, FCC, or BP/Ph.Eur. grades, as required. Key parameters including assay, heavy metal content, and identification are rigorously verified. A comprehensive Certificate of Analysis (COA) is provided with every shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
