High Purity EDTA2Na Suppliers in China Leading Ethylenediaminetetraacetic Acid Disodium Salt Factory
Description
Ethylenediaminetetraacetic Acid Disodium Salt (EDTA-2Na) is a high-performance chelating agent renowned for its exceptional ability to sequester metal ions. Utilizing a hexadentate ligand structure, it forms highly stable, ring-like coordination complexes with metal ions such as Fe³⁺, Cu²⁺, and Ca²⁺, effectively neutralizing their catalytic activity and preventing unwanted chemical reactions in complex formulations.
As a cornerstone of modern industrial chemistry, EDTA-2Na is indispensable across diverse sectors. From enhancing the stability and shelf life of premium cosmetics and personal care products to boosting the cleaning efficiency of industrial detergents and serving as a critical anticoagulant in medical diagnostics, its versatility ensures superior product integrity and performance on a global scale.

Frequently Asked Questions
Q: What is the primary function of EDTA-2Na in cosmetics?
In cosmetics, EDTA-2Na acts as a stabilizer by chelating trace metal ions that catalyze the oxidation of fats and fragrances, thereby preventing rancidity and extending shelf life.
Q: How does EDTA-2Na improve detergent performance?
It serves as a water softener by binding calcium and magnesium ions, which prevents these ions from interfering with surfactants, thus increasing foam and cleaning power.
Q: Is EDTA-2Na safe for use in food products?
Yes, it is an approved food preservative known as E385, used to maintain color and flavor in canned goods, beverages, and dressings.
Q: Why is EDTA-2Na used in blood collection tubes?
It acts as a powerful anticoagulant by chelating the calcium ions necessary for the blood clotting cascade, making it ideal for hematological testing.
Q: What is the meaning of "hexadentate ligand" in this context?
A hexadentate ligand can form six separate coordination bonds with a single metal ion, effectively "wrapping" the ion in a stable complex to render it inactive.
Q: What is the typical solubility of EDTA-2Na?
EDTA-2Na is freely soluble in water, making it easy to integrate into aqueous formulations such as shampoos, lotions, and buffer solutions.
