HEDP wani abu ne mai hana lalata sinadarai na organophosphoric acid. Yana iya yin chelate da Fe, Cu, da Zn ions don samar da sinadarai masu ƙarfi. Yana iya narkar da kayan da aka yi wa oxidized a saman waɗannan ƙarfe. HEDP yana nuna kyakkyawan tasirin sikelin da hana lalata a ƙarƙashin zafin jiki 250℃. HEDP yana da kyakkyawan daidaiton sinadarai a ƙarƙashin ƙimar pH mai yawa, yana da wahalar hydrolyzed, kuma yana da wuyar ruɓewa a ƙarƙashin haske da yanayin zafi na yau da kullun. Juriyar iskar acid/alkali da chlorine sun fi na sauran acid organophosphoric (gishiri). HEDP zai iya amsawa da ions na ƙarfe a cikin tsarin ruwa don samar da hadaddun chelating hexa-element, musamman tare da ion na calcium. Saboda haka, HEDP yana da kyawawan tasirin hana sikelin da kuma bayyane. Idan aka gina shi tare da sauran sinadarai na maganin ruwa, yana nuna kyakkyawan tasirin haɗin gwiwa. HEDP foda ne mai lu'ulu'u, wanda ya dace da amfani a yankunan hunturu da sanyi. Saboda yawan tsarkinsa, ana iya amfani da shi azaman mai tsaftacewa a filayen lantarki da kuma azaman ƙari a cikin sinadarai na yau da kullun.
HEDP Ana amfani da shi azaman hana sikelin da tsatsa a cikin tsarin ruwan sanyi mai yawo, filin mai da tukunyar ruwa mai ƙarancin matsin lamba a fannoni kamar wutar lantarki, masana'antar sinadarai, aikin ƙarfe, taki, da sauransu. A cikin masana'antar saka mai sauƙi, HEDP ana amfani da shi azaman sabulun wanke ƙarfe da wanda ba ƙarfe ba. A masana'antar rini, HEDP ana amfani da shi azaman mai daidaita peroxide da wakilin gyara rini; A cikin electroplating mara cyanide, HEDP ana amfani da shi azaman maganin chelating. Ana fifita yawan 1-10mg/L a matsayin maganin hana sikelin, 10-50mg/L a matsayin maganin hana tsatsa, da kuma 1000-2000mg/L a matsayin sabulun wanki. Yawanci, HEDP Ana amfani da shi tare da polycarboxylic acid.
