Production Method:
EDTA Disodium is produced through a controlled chemical reaction involving ethylenediaminetetraacetic acid (EDTA) and sodium hydroxide (NaOH). The process includes:
Dissolution: EDTA is dissolved in water.
Neutralization: Sodium hydroxide is added to achieve the correct pH balance.
Filtration & Purification: The solution undergoes filtration to remove impurities.
Crystallization: The purified solution is cooled to crystallize EDTA Disodium.
Drying & Packaging: The final product is dried, ground, and packed for global distribution.
Raw Materials:
Ethylenediaminetetraacetic Acid (EDTA)
Sodium Hydroxide (NaOH)
Water
Working Principle:
EDTA Disodium acts as a powerful chelating agent, binding with metal ions such as calcium, magnesium, iron, and lead. This prevents undesirable reactions in chemical processes, improving the efficiency of industrial formulations, cleaning agents, cosmetics, and water treatment solutions.
Applications:
Water Treatment: Removes heavy metal ions from industrial and municipal water systems.
Pharmaceuticals: Used as a stabilizer in drug formulations and intravenous solutions.
Cosmetics & Personal Care: Enhances the effectiveness and shelf life of skincare products, shampoos, and creams.
Detergents & Cleaning Agents: Prevents metal ion interference, ensuring better cleaning performance.
Textile & Paper Industry: Improves dyeing efficiency and prevents fabric discoloration.
Food Industry (E385): Used in select food products as a preservative and color stabilizer.
