White odorless, tasteless, colorless crystalline powder, melting point 250ºC (decomposition). Insoluble in ethanol and general organic solvents, slightly soluble in cold water, soluble in aqueous solutions of sodium h ydroxide, sodium carbonate and ammoni a. Soluble in more than 5% inorganic acid, also soluble in ammoni a and 160 parts boiling water. Its alkali salts are soluble in water.
Disodium EDTA is a chemical that is used as a food preservative that is commonly found in salad dressings, sauces, spreads, canned goods, and beverages. (Food production licence approved for food-grade quality.)
It is also present as a preservative in soaps, shampoos, and cosmetics. (Industrial grade quality.)
It is both odourless and colourless and works to preserve foods and creams by binding with various minerals and metals.
Disodium EDTA and Calcium Disodium EDTA are often confused for each other, but they are very different chemicals despite the fact that both are commonly referred to as simply EDTA. It is extremely important not to get the two mixed up.
Product: EDTA (Ethylene Diamine Tetraacetic Acid, EDTA Acid, Editic Acid)
Molecular Formula: C10H16N2O8

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. |
