•  The difference in Use Between EDTA Disodium and Tetrasodium

There are two basic kinds of EDTA available to home crafters, so be sure to buy the correct type. Tetrasodium EDTA should be used in soap and other alkaline products. Disodium EDTA is the other kind of EDTA; it should only be used in neutral pH to slightly acidic products.

Tetrasodium EDTA is available in two forms: a powder that is about 99%min pure EDTA and liquid that is usually a solution of 40% EDTA in water. Either form can be used. The powder has dihydrate and the general tetrahydrate.
