What is EDTA?
EDTA (ethylenediaminetetraacetic acid) is an aminopolycarboxylic acid that appears as a colourless and water-soluble solid. This compound can also be produced as different forms of salt, such as disodium EDTA, calcium EDTA and tetrasodium EDTA.
Although it is used in multiple applications, from buffer solutions to additives and water testing, the most important use of EDTA is as a chelating agent. This is because it has the ability to bind several polyvalent cations, like calcium or iron. For example, in the textile industry, it is used to prevent impurities (mostly in the form of metal ions) from modifying the final colours of the products.
Similarly, in the paper industry, the use of EDTA inhibits the activity of metal ions from promoting the disproportionation of hydrogen peroxide, which would have serious consequences during bleaching. Finally, this metal-buddy compound is also a common ingredient in many soaps and detergents, forming complexes with calcium and magnesium in order to stop its interference with the cleaning process.
In its pure form, ethylenediaminetetraacetic acid is classed as an irritant, particularly to the eyes. However, diluted solutions are less dangerous, making this compound very appealing as it can inactivate metal ions in a relatively safe manner compared to stronger acids that are also capable of dissolving metals.
Nevertheless, it is still vital that all those handling EDTA do so safely by consulting the MSDS Sheet, which is available to download from our website, and by using appropriate PPE (Personal Protective Equipment).
