Product Description

EDTA-4Na Liquid

EDTA-4Na Liquid is the tetrasodium salt of ethylenediaminetetraacetic acid (EDTA) in aqueous form. It is a chelating agent widely used to bind metal ions, soften water, and enhance the stability and performance of various formulations. In liquid form, EDTA-4Na is convenient for handling and mixing in industrial and commercial applications. It is highly effective in sequestering metal ions such as calcium, magnesium, iron, and copper, preventing undesirable reactions in a variety of industries.
