HEDP He aukati waikura waikawa organophosphoric. Ka taea e ia te hono atu ki ngā katote Fe, Cu, me Zn hei hanga i ngā pūhui chelating pumau. Ka taea e ia te whakarewa i ngā rauemi kua waikurahia i runga i ngā mata o ēnei konganuku. HEDP he tino pai ngā pānga aukati i te tauine me te waikura i raro i te pāmahana 250℃. HEDP He pai te pumau matū i raro i te pH teitei, he uaua ki te whakawhaiti, ā, he uaua ki te pirau i raro i ngā āhuatanga mārama me te wera noa. He pai ake tōna ātete ki te waikawa/kawakore me te waikura haukini i ērā atu waikawa organophosphoric (tote). HEDP ka taea te tauhohe ki ngā katote konganuku i roto i te pūnaha wai hei hanga i te matatini chelating huānga-hexa, me te katote konupūmā. Nō reira, HEDP he pai ngā pānga ārai-tauine me ngā pānga paepae e kitea ana. Ina hangaia ngātahitia me ētahi atu matū maimoatanga wai, ka whakaatuhia he pānga mahi tahi pai. Ko te āhua totoka o HEDP He paura tioata tēnei, he pai mō te whakamahi i te takurua me ngā rohe hukapapa. Nā tōna parakore teitei, ka taea te whakamahi hei horoi i ngā mara hiko me te tāpiri i ngā matū o ia rā.
HEDP e whakamahia ana hei aukati i te tauine me te waikura i roto i te pūnaha wai matao e rere ana, te mara hinu me ngā kohua pēhanga iti i roto i ngā mara pēnei i te hiko, te ahumahi matū, te whakarewa, te tongi, me ētahi atu. I roto i te ahumahi whatu māmā, HEDP e whakamahia ana hei hopi horoi mō te mea whakarewa me te mea kore-whakarewa. I roto i te umanga tae, HEDP e whakamahia ana hei whakaū i te peroxide me te kaihoko whakapiri tae; I roto i te whakakikorua hiko kore-cyanide, HEDP e whakamahia ana hei kaihoko chelating. Ko te horopeta o te 1-10mg/L te mea e pai ake ana hei aukati unahi, 10-50mg/L hei aukati waikura, me te 1000-2000mg/L hei hopi horoi. I te nuinga o te wā, HEDP ka whakamahia ngātahi me te waikawa polycarboxylic.
