EDTA-2NA 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.
