Disodium ethylenediaminetetraacetate (inozivikanwawo se disodium EDTA) ine simba chelating agent. Nekuda kwekugadzikana kwayo kwakanyanya uye yakawedzera kurongeka kwezvinhu, inogona kunge yakabatana neakawanda simbi ions kunze kwealkali simbi (Senge iron, mhangura, calcium, magnesium uye mamwe akawanda ion ion) chelate kuti igadzire yakagadzikana inonyungudika mvura, inobvisa simbi ions kana maitiro anokuvadza anokonzerwa navo.

Disodium EDTA iwhite crystalline powder inonyungudika mumvura uye inenge isinganyungudike mu ethanol ne ether. Iyo pH kukosha kweiyo aqueous solution ingangoita 5.3 uye inoshandiswa mukuchenesa, dhayi anobatsira, fiber processing agents, cosmetic additives, chikafu chekuwedzera, zvekurima micro-fertilizer uye Mariculture, nezvimwe.
