Is EDTA and disodium EDTA same?
Disodium EDTA and tetrasodium EDTA are byproducts of EDTA synthesis process. They are sodium salts of EDTA. The main difference between disodium EDTA and tetrasodium EDTA is that disodium EDTA has a pH lower than 7 whereas tetrasodium EDTA has a pH higher than 7.

Is disodium EDTA good for skin?
Calcium disodium EDTA is widely used in beauty and cosmetic products. It allows for better cleaning use, as it enables cosmetic products to foam. What’s more, as it binds with metal ions, it prevents metals from accumulating on the skin, scalp or hair ( 4 ).
What is the use of disodium EDTA?
What is edetate disodium? Edetate disodium (EDTA) is a chelating (KEE-late-ing) agent. A chelating agent is capable of removing a heavy metal, such as lead or mercury, from the blood. EDTA is used to lower blood levels of calcium when they have become dangerously high.
What does EDTA mean?
Ethylenediamine tetraacetic acid
Ethylenediamine tetraacetic acid (EDTA) is a polyprotic acid containing four carboxylic acid groups and two amine groups with lone-pair electrons that chelate calcium and several other metal ions.
What is the principle of EDTA titration?
EDTA is Ethylene diamine tetra acetic acid. It dissolves in water with great difficulty, but its disodium salt dissolve in water quickly & completely It is hexa dentate ligend. It binds the metal ions in water to give stable chelate complex. Hence it is called as complexometric titration method.
Why is disodium EDTA used instead of free EDTA?
Hardness of water is determined by titrating with a standard solution of ethylene diamine tetra acetic acid (EDTA) which is a complexing agent. Since EDTA is insoluble in water, the disodium salt of EDTA is taken for this experiment.
Is disodium EDTA safe in cosmetics?
Used as a chelating agent in cosmetic products, meaning it prevents ingredients in a formula from binding with trace elements (mainly minerals) that can be present in water. Studies have found that EDTAs, including disodium EDTA, as used in cosmetic formulations are safe.
How do you make 0.5 M EDTA pH 8?
To prepare EDTA at 0.5 M (pH 8.0): Add 186.1 g of disodium EDTA•2H2O to 800 mL of H2O. Stir vigorously on a magnetic stirrer. Adjust the pH to 8.0 with NaOH (~20 g of NaOH pellets). Dispense into aliquots and sterilize by autoclaving.
What is the difference between EDTA and EDTA disodium salt?
EDTA is a tetrabasic acid. It is essentially insoluble in water. The disodium salt is soluble in water at room temperature up to a concentration of 0.26 mol/L. The pH of the solution is in the range of 4 to 6.At pH 8.5 a 0.5 mol/L solution at 4 °C is stable for months.
What is equivalent weight of disodium EDTA salt?

What are the side effects of edetate disodium ( EDTA )?
International Journal of Toxicology 21 (S2): 95-142 (2002) Edetate disodium ( EDTA) is a chelating agent which has no place in the treatment of atherosclerosis and its complications. Also, its toxic effects can cause other problems which may lead to a fatal outcome.
Which is the most common form of EDTA?
The Disodium salt of EDTA is the most commonly used form of this versatile organic complexing agent, which is used for the determination of many metal ions either by direct titration or by back-titration.
