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. |
