HEDP waa daawo ka hortagta daxalka aashitada organophosphoric. Waxay ku milmi kartaa aashitada Fe, Cu, iyo Zn si ay u sameeyaan iskudhisyo chelating ah oo deggan. Waxay milmi kartaa walxaha oksaydhka leh ee ku yaal dusha sare ee birahan. HEDP waxay muujinaysaa saameyn heer sare ah oo ku saabsan miisaanka iyo xakamaynta daxalka marka heerkulku yahay 250℃. HEDP wuxuu leeyahay xasillooni kiimiko oo wanaagsan marka uu ku jiro qiimaha pH-ga sare, way adag tahay in la hawo-geliyo, waana adag tahay in la burburiyo marka la eego iftiinka caadiga ah iyo kulaylka. Adkeysiga oksaydheynta aashitada/alkali iyo koloriinku way ka fiican yihiin aashitada kale ee organophosphoric (cusbo). HEDP waxay la falgeli kartaa ayoonnada birta ah ee ku jira nidaamka biyaha si ay u sameeyaan isku-dhafka chelating-ka hexa-element, gaar ahaan calcium ion. Sidaa darteed, HEDP waxay leedahay saameyn wanaagsan oo ka hortag ah iyo mid muuqata. Marka lala dhiso kiimikooyinka kale ee daaweynta biyaha, waxay muujinaysaa saameyn wanaagsan oo isku-dhafan. Xaaladda adag ee HEDP waa budo kiristaal ah, oo ku habboon in loo isticmaalo jiilaalka iyo meelaha barafoobay. Sababtoo ah nadiifnimadeeda sare, waxaa loo isticmaali karaa sidii wakiil nadiifin ah oo ku jira goobaha elektaroonigga ah iyo sidoo kale waxyaabo lagu daro kiimikooyinka maalinlaha ah.
HEDP waxaa loo isticmaalaa sidii xakamaynta miisaanka iyo daxalka ee nidaamka biyaha qabow ee wareegaya, goobta saliidda iyo kuleyliyeyaasha cadaadiska hooseeya ee beeraha sida korontada, warshadaha kiimikada, birta, bacriminta, iwm. Warshadaha tolmada fudud, HEDP waxaa loo isticmaalaa saabuun ahaan loogu talagalay biraha iyo kuwa aan biraha ahayn. Warshadaha rinjiyeynta, HEDP waxaa loo isticmaalaa sidii xasiliye peroxide ah iyo wakiil hagaajinaya rinjiga; HEDP waxaa loo isticmaalaa sidii wakiil chelating ah. Qiyaasta 1-10mg/L waxaa loo door bidaa inay tahay daawo miisaanka ka hortagta, 10-50mg/L oo ah daawo daxalka joojisa, iyo 1000-2000mg/L oo ah saabuun. Badanaa, HEDP waxaa lala isticmaalaa polycarboxylic acid.
