Description

Ethylenediaminetetraacetic Acid Tetrasodium Salt Trihydrate is a high-purity, water-soluble chelating agent widely used to sequester di- and trivalent metal ions. This compound is critical for processes requiring precise control of metal ion activity to prevent unwanted catalysis, precipitation, or discoloration. It is an essential raw material for manufacturers in the pharmaceutical, food & beverage, personal care, and industrial cleaning sectors seeking reliable and consistent chelation performance.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent in formulations to chelate trace metals that can catalyze oxidation and degrade active pharmaceutical ingredients (APIs).
• Food & Beverage Industry (FCC Grade): Acts as a preservative and color/ flavor stabilizer in canned goods, dressings, and beverages by binding metal ions that cause spoilage and rancidity.
• Personal Care & Cosmetics: Incorporated into creams, lotions, and shampoos to improve product stability and shelf-life by sequestering hardness ions from water.
• Industrial Cleaning & Detergents: Enhances the efficacy of cleaning formulations by softening water and preventing scale formation on equipment and surfaces.
• Textile Processing: Serves as a chelant in dyeing and finishing baths to prevent metal-ion interference, ensuring consistent and vibrant color results.
• Laboratory & Analytical Chemistry: Used as a key component in buffer solutions, titrants, and reagents for complexometric titrations and metal ion analysis.
• Pulp & Paper Production: Helps in bleaching processes by deactivating metal ions that catalyze the decomposition of bleaching agents like hydrogen peroxide.
• Agricultural Chemicals: Used in certain micronutrient fertilizers and pesticide formulations to improve stability and bioavailability.
