Polyethylene glycol (PEG)i-polymer ephezulu ye-molecular enyibilikayo emanzini eyenziwe yi-polymerization ye-ethylene oxide. Ngenxa ye-hydrophilicity yayo egqwesileyo, i-biocompatibility kunye nokuzinza kweekhemikhali, isetyenziswa kakhulu kumashishini angundoqo afana namayeza, iikhemikhali zemihla ngemihla, ezolimo, irabha kunye namalaphu.
Njengomthengisi oqeqeshiweyo ozinikele kwintsimi yeekhemikhali ezintle, i-Dotachem inikezela uluhlu olupheleleyo lweemveliso ze-PEG ezinobunzima be-molecular ukusuka kwi-200 ukuya kwi-8000 +.
Iimpawu ezibonakalayo ze-PEG zixhomekeke kakhulu kubunzima bayo bemolekyuli.
I-PEG-200 ukuya kwi-PEG-600: Ubunzima bemolekyuli obuphantsi, ulwelo. Zine-viscosity ephantsi kunye ne-solubility egqwesileyo yamanzi, kwaye zisetyenziswa ngokuqhelekileyo njengezinyibilikisi ezigqwesileyo, iiplastiki zeplastiki kunye ne-humectants, zisetyenziswa ngokubanzi kumalungiselelo e-cosmetic kunye namayeza olwelo.
I-PEG-1000 ukuya kwi-PEG-4000: Ubunzima bemolekyuli obuphakathi, i-waxy solids. Njengoko ubunzima bemolekyuli bukhula, kunjalo ke i-viscosity kunye nenqanaba lokunyibilika. Umzekelo, i-PEG-3350 sisisiseko esisetyenziswa ngokuqhelekileyo kwi-suppository kunye ne-ointment kwi-pharmaceuticals, ebonelela ngokubumba kakuhle kunye nokusebenza kokukhutshwa kweziyobisi.
I-PEG-6000 nangaphezulu: Ubunzima bemolekyuli obuphezulu, buqinile. Inobunzima obuphezulu kunye nendawo yokunyibilika, kwaye iqhele ukusetyenziswa njengesixhobo sokwenza isinyithi, i-lubricant yethebhulethi okanye i-ejenti yokulinganisa i-textile, ibonelela ngokugqwesa ukuthanjiswa kunye neziphumo zokusasazwa.
Ukukhetha umboneleli we-PEG othembekileyo kubaluleke kakhulu. Ukukhetha ngokuchanekileyo ukuchazwa kobunzima bemolekyuli kunye nokuqinisekisa ukucoceka okuphezulu kunye nokuzinza kwebhetshi yemveliso kuyadingeka ukuze kusetyenziswe ngokupheleleyo ukusebenza kwe-PEG kwinkqubo yokuvelisa.
I-Dotachem inokubonelela ngoluhlu olupheleleyo lweemveliso ukusukaI-PEG-200 ukuya kwi-PEG-20000, ukuhlangabezana neemfuno zakho ezahlukeneyo ukusuka kwizinto zokuthambisa, amayeza ukuya kwizicelo zamashishini. Siqinisekisa ukuba yonke ibhetshi yeemveliso inomgangatho ophezulu wokusebenza. Nceda uzive ukhululekile ukuqhagamshelana nathi nanini na ukufumana ikhathalogu yemveliso eneenkcukacha kunye nokubonisana nobugcisa.
