I-Polyethylene glycol ineepropathi ezahlukeneyo ngokuxhomekeke kubunzima bayo beemolekyuli, ukusuka kulwelo olungenambala kunye nolungenamuncu we-viscous ukuya kwi-wax eqinileyo. Xa ubunzima beemolekyuli bungu-200-600, lulwelo kubushushu begumbi. Xa ubunzima bemolekyuli bungaphezulu kwama-600, ngokuthe ngcembe buyaqina. Ngumahluko wobunzima bemilinganiselo yeemolekyuli, iipropathi zahlukile. Ukusuka kulwelo olungenambala kunye nolungenamuncu we-viscous ukuya kwi-wax eqinileyo. Ngokunyuka kobunzima beemolekyuli, i-hygroscopicity iyancipha.I-Peg-400 ilungile kwiifomsile ezithambileyo. Kuba i-PEG400 lulwelo, inokudityaniswa okubanzi kwezinyibilikisi ezahlukeneyo, isisinyibilikisi elungileyo kunye nesinyibilikisi, isetyenziswa ngokubanzi kumalungiselelo alulwelo, afana nolwelo lomlomo, amathontsi wamehlo, njl njl. ophetheyo. Oku ikakhulu kungenxa yokuba i-PEG izinzile kwaye ayinakonakala, kwaye inaliti ene-PEG ikhuselekile kwaye izinzile xa ishushu ukuya kwi-150 degrees Celsius. Ukongeza, inokuxutywa nobunzima obuphezulu beemolekyuli (i-PEG) kunye nomxube wayo unokunyibilika okuhle kunye nokuhambelana neziyobisi. Isetyenziswa njenge matrix yeyeza kunye nezithambiso, igrisi kunye nokumanzisa iarhente kwishishini leerabha nakwimizi-mveliso yempahla elukiweyo.
Iimveliso zoluhlu lwe-Polyethylene glycol zinokusetyenziswa kwiimveliso zamayeza. Ubunzima be-molecular molecular polyethylene glycol (i-PEG) ingasetyenziselwa isisombululo, i-cosolvent, i-O / W i-emulsifier kunye ne-stabilizer, ukumiswa, i-emulsion, esetyenziselwa ukwenza inaliti yesamente, njl njl. i-matrix, i-matrix yesisindo esiphezulu se-molecular waxy polyethylene glycol (i-PEG) ihlala isetyenziselwa ukwandisa i-PEG viscosity kunye ne-low molecular weight liquid to solid, kunye nezinye iziyobisi; Amachiza angenakunyibilika emanzini, le mveliso inokusetyenziswa njengesixhobo sokusasaza esiqinileyo ukufezekisa injongo eqinileyo yokusasaza.
