製品説明
式: C10H16N2O8
CAS: 60-00-4
外観:白い粉
配位錯体に分子を置換するのが非常に優れているため、EDTAを使用して、微量の微量の金属を防ぐことができます
製品に反応し、有害な影響を与えることから。
一般に、EDTAは金属の反応性を低下させ、その存在から生じる可能性のある望ましくない効果を防ぎます。
EDTAは塩の形で使用され、おそらくDisodium(EDTA-2NA)またはCalcium Disodium EDTA(EDTA-CANA2)で使用されます。

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. |
