Product Summary
EDTA-2Na (Ethylenediaminetetraacetic Acid Disodium Salt) is a highly effective chelating agent used to bind metal ions such as calcium, magnesium, iron, and copper. It is widely utilized in various industries, including cosmetics, pharmaceuticals, food processing, and water treatment. By sequestering metal ions, EDTA-2Na helps to improve product stability, prevent metal ion-induced degradation, and extend shelf life. It is an essential ingredient in many formulations, providing versatility and reliability across diverse applications.
Introduction
EDTA-2Na is the disodium salt form of ethylenediaminetetraacetic acid, a chelating agent that is highly effective at forming stable complexes with metal ions. It is commonly used in industries where metal ions may interfere with the stability, color, or efficacy of the product. EDTA-2Na prevents the negative effects of metal ions, such as discoloration, chemical degradation, and loss of efficacy, making it a vital component in many formulations, particularly in personal care products, pharmaceuticals, and industrial applications.
Structure
The structure of EDTA-2Na consists of an ethylenediamine backbone, which is attached to four carboxylate groups capable of binding to metal ions. The disodium salt form of EDTA-2Na enhances its solubility in water and enables it to efficiently chelate metal ions, making it an effective stabilizing agent for a wide range of formulations.
