Product Description
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
CAS NO.:60-00-4
Molecular Weight:M=292.2
Feature: EDTA is a white crystal powder,insoluble in common organic solvents,soluble in boiling water 160 times as much and in alkali solvents like so dium hy droxide. At 150°C, it shows the tendency to depart from carboxyl.
Melting point: 240°C(decomposition)
Dissolving degree in water: 0.5g/L(25°C).
Ethylenediami tetraacetic acid (EDTA) is an important chelating agent with a chemical formula of C10H16N2O8. It is a white powder at room temperature and pressure. It has six coordinating atoms and can form stable complexes with a variety of metal ions. This complex is called a chelate. EDTA has a wide range of uses, including but not limited to color photosensitive material processing, dyeing auxiliaries, fiber processing auxiliaries, cosmetic additives, blood anticoagulants, detergent stabilizers, synthetic rubber polymerization initiators, etc. In addition, EDTA can also form stable water-soluble complexes with alkali metals, rare earth elements and transition metals, so it has important applications in many fields.
EDTA, as a chelating agent, can bind to divalent metal ions such as Mg2+, Ca2+, Mn2+, Fe2+, etc. These ions are essential for the action of many enzymes. Therefore, EDTA and its salts are often used as inhibitors of nucleases, and are also used to remove the inhibitory effect of heavy metal ions on enzymes. For example, in the medical field, EDTA can be used as a blood anticoagulant to help prevent blood coagulation.
In addition, EDTA can form a tight bond with toxic heavy metals, helping to dissolve calcium oxalate crystals and is used in food, chelation experiments, and many household products. It has also been studied and applied to treat lead poisoning by combining with lead to form a soluble and stable complex, promoting its excretion from the body.
In general, EDTA is a versatile and important chemical reagent that plays a key role in many fields, from medical treatment, industry to environmental protection, and has its unique value and uses.

TEST CONCLUSION | PASS | ||
EDTA 4NA is an important complexing agent and metal masking agent.It can be used in textile industry dyeing, water treatment, color sensitization, medicine, daily chemical industry, paper making and other industries as additives, activators, water purification agents, metal ion masking agents and activators in Styrene-butadiene industry.
In the dry process acrylic industry, it can offset metal interference, improve the color and brightness of dyed fabrics, and can also be used in liquid detergents to improve washingquality and enhance washing effects.
Product Usage :
| 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. |
