HEDP ni umuti ubuza aside organophosphorus corrosion. Ishobora gushonga hamwe na iyoni za Fe, Cu, na Zn kugira ngo ikore ibintu bihamye bya chelating. Ishobora gushonga ibikoresho bya oxidized ku buso bw'ibi byuma. HEDP igaragaza ingaruka nziza cyane ku bushyuhe bwa 250°C. HEDP Ifite ubushobozi bwo kudahinduka mu buryo busanzwe bw’ibinyabutabire iyo ifite pH iri hejuru, igoranye gushonga, kandi igoranye kubora mu gihe cy’urumuri n’ubushyuhe busanzwe. Ishobora kwihanganira aside/alkali na chlorine oxidation kurusha izindi aside organophosphorus (umunyu). HEDP ishobora gukorana na iyoni z'icyuma mu buryo bw'amazi bigatuma ikora ubwoko bwa hexa-element chelating complex, cyane cyane iyoni ya kalisiyumu. Kubera iyo mpamvu, HEDP ifite ingaruka nziza zo kurwanya ubunini n'ingaruka zigaragara. Iyo yubatswe hamwe n'indi miti itunganya amazi, igaragaza ingaruka nziza zo guhuza. Imiterere ikomeye ya HEDP ni ifu ya kristu, ikwiriye gukoreshwa mu gihe cy'itumba no mu turere dukonje. Kubera ko ifite ubuziranenge bwinshi, ishobora gukoreshwa nk'isuku mu bikoresho by'ikoranabuhanga ndetse no mu binyabutabire bya buri munsi.
HEDP ikoreshwa nk'uburyo bwo gukumira ingese mu miyoboro y'amazi akonje, mu mashini zikoresha peteroli no mu byuma bishyushya amazi bifite umuvuduko muto mu mashini nko mu amashanyarazi, mu nganda zikora imiti, mu byuma, mu ifumbire, n'ibindi. Mu nganda ziboshye mu buryo bworoheje, HEDP ikoreshwa nk'isabune yo mu byuma n'ibitari ibyuma. Mu nganda zisiga amarangi, HEDP ikoreshwa nk'ikintu gikomeza peroxide no gushyiraho irangi; Mu gukoresha electroplating itari cyanide, HEDP ikoreshwa nk'umuti ugabanya ubushyuhe. Igipimo cya 1-10mg/L gikundwa cyane nk'umuti ugabanya ubushyuhe, 10-50mg/L nk'umuti ugabanya ubushyuhe, na 1000-2000mg/L nk'isabune. Ubusanzwe, HEDP ikoreshwa hamwe na aside polycarboxylic.
