EDTA-2NA and EDTA-4NA are white crystal powders with two crystals of water,
easy to lose crystal water when dried and easy to soluble in water,
but hard to soluble in organic solvents like alcohol or ethyl ether.
The pH value of 5%(25 °C ) aqueous solution is 4.0~6.0.

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.
