EDTA Disodium (Cosmetic) (Water Soluble)

CAS No: 6381-92-6 Formula: C10H14N2Na2O8.2H2O M.W. 372.24

The pH range of a solution of EDTA disodium (Ethylenediaminetetraacetic acid disodium salt) typically falls between 4 and 6 in water. However, when dissolved in a buffer solution, the pH can be adjusted to a wider range, depending on the buffer used. EDTA disodium is often used in slightly alkaline conditions, typically around pH 7 to 9, to enhance its chelating ability, particularly for binding metal ions.
