Disodium ethylenediaminetetraacetate (yomwe imadziwikanso kuti disodium EDTA) ndi chelating agent yamphamvu. Chifukwa cha kukhazikika kwake kosalekeza komanso kulumikizana kwakukulu, imatha kuyanjana ndi ayoni ambiri achitsulo kupatula zitsulo zamchere (Monga chitsulo, mkuwa, calcium, magnesium ndi ma ion ena ambiri) chelate kuti ipange zovuta zosungunuka m'madzi, kuchotsa ma ion zitsulo kapena zotsatira zoipa chifukwa iwo.

Disodium EDTA ndi ufa woyera wa crystalline womwe umasungunuka m'madzi ndipo pafupifupi wosasungunuka mu ethanol ndi ether. Mtengo wa pH wa yankho lake lamadzi ndi pafupifupi 5.3 ndipo umagwiritsidwa ntchito mu zotsukira, zopangira utoto, zopangira ma fiber, zowonjezera zodzikongoletsera, zowonjezera chakudya, feteleza zazing'ono zaulimi ndi Mariculture, ndi zina zambiri.
