What is EDTA-2NA Disodium Edetate Dihydrate CAS 139-33-3?
EDTA has a wide range of coordination properties, and can form stable chelates with almost all metal ions. Advantages: it provides the possibility to determine elements widely (better than acid-base and precipitation methods). Disadvantages: it is easy to interfere between various components - selectivity The coordination ratio of EDTA to the formed M-EDTA is mostly 1:13. Most of the chelates are charged, so they can be dissolved in water and react quickly.Application
| Applications | How does EDTA work? |
| Industrial uses | EDTA chelating agents are widely used in water treatment, dyeing, oil cleaning, etc. |
| Personal care & skincare products | Binding to free metal ions and serves as a purifying agent and preservative. |
| Shampoos and soaps | Reducing the "hardness" (or presence of metal cations) in tap water so that other ingredients can work to cleanse more efficiently. |
| Laundry detergents | To soften water that comes into contact with it so the other active ingredients can cleanse better. |
| Textiles | Preventing the discolouring of dyed fabrics by removing harmful free metal ions and getting rid of residue left on industrial equipment. |
| Agriculture Fertilizers | EDTA metal salts like EDTA-Mn, EDTA-Fe and EDTA-Zn, etc are mainly used as foliar fertilizers, water-soluble fertilizers to supply trace elements for vegetables, crops, and fruits. |
| Foods | EDTA chelating agents are used for chelating metal ions, removing heavy metals of foods. EDTA metal salts e.g. Ca, Zn, Fe, are used for supplying micronutrients for human. |
