HEDP shi ne mai hana organophosphoric acid lalata. Yana iya chelate da Fe, Cu, da Zn ions don samar da barga chelating mahadi.Yana iya narkar da oxidized kayan a kan wadannan karafa' saman.HEDPyana nuna kyakkyawan ma'auni da tasirin hana lalata a ƙarƙashin zafin jiki na 250 ℃.HEDP yana da kyakkyawan kwanciyar hankali na sinadarai a ƙarƙashin ƙimar pH mai girma, mai wuyar gurɓata ruwa, kuma yana da wuya a ruɓe ƙarƙashin haske na yau da kullun da yanayin zafi. Its acid/alkali da chlorine oxidation haƙuri sun fi na sauran organophosphoric acid (gishiri).HEDP zai iya amsawa tare da ions karfe a cikin tsarin ruwa don samar da hadaddun chelating na hexa-element, tare da ion calcium musamman. Don haka,HEDP yana da kyau antiscale da bayyane kofa effects. Lokacin da aka gina tare da wasu sinadarai na maganin ruwa, yana nuna sakamako mai kyau na aiki tare. A m hali naHEDP ne crystal foda, dace da amfani a cikin hunturu da kuma daskarewa gundumomi. Saboda girman tsarkinsa, ana iya amfani da shi azaman wakili mai tsaftacewa a cikin filayen lantarki da ƙari a cikin sinadarai na yau da kullun.
