What are the properties of EDTA?

What are the properties of EDTA?

Physical Properties of EDTA EDTA is white powder, which is soluble in sodium hydroxide, sodium carbonate and ammonia solution, and 160 parts of boiling water, and slightly soluble in cold water, insoluble in ethanol and general organic solvents.

What is tetrasodium EDTA used for?

Tetrasodium EDTA is a chelating agent used to prevent minerals and metals present in water-based formulations from bonding to other ingredients and impacting their efficacy.

Is tetrasodium EDTA a chelating agent?

EDTA (ethylenediaminetetraacetic acid) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in a product.

What is tetrasodium EDTA made of?

It is made from sodium cyanide and formaldehyde. The way Tetrasodium EDTA is considered suspect by many skincare agents. However, the compound is not considered a carcinogen.

What is the difference between disodium EDTA and tetrasodium EDTA?

They are sodium salts of EDTA. Disodium EDTA has two sodium cations whereas tetrasodium EDTA has four sodium cations per molecule. 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.

How does EDTA react with metal ions?

Solid EDTA is readily dissolved in water where it can form multiple chemical bonds with many metal ions in a solution, in effect tying up the metal ions. A molecule such as EDTA which has at least one free pair of unbonded electrons and therefore can form chemical bonds with metal ions.

Is tetrasodium EDTA the same as EDTA?

Is tetrasodium EDTA natural or synthetic?

Also known as ethylenediaminetetraacetic acid (or short for edetic acid), is an odorless, water-soluble crystalline that is a synthetic ingredient from ethylenediamine, formaldehyde, and sodium cyanide.

Is Tetrasodium EDTA a mineral?

Tetrasodium EDTA is a salt of Ethylenediamine Tetraacetic Acid (EDTA), another chelating compound. When creating a synthetic compound, several materials react together to obtain a new one. Often, they can contain minerals and metal ions that can prevent the reaction from taking place properly.

Is Tetrasodium EDTA corrosive?

The EDTA acts as a cathodic stimulant and high rates of corrosion can occur even in the absence of dissolved oxygen.

Is tetrasodium EDTA a mineral?

What is the pH of tetrasodium EDTA?

approximately 11.3
It is used as a source of the chelating agent EDTA4-. A 1% aqueous solution has a pH of approximately 11.3….Tetrasodium EDTA.
