Polyethylene Glycol 4000

Inombolo yeCAS: 25322-68-3

I-Polyethylene Glycol 4000 luhlobo lwepolymer ephezulu, ifomula yekhemikhali yi-HO (CH2CH2O) nH, engacaphukiyo, incasa ekrakra, inonyibiliko oluhle lwamanzi, kunye nezinto ezininzi eziphilayo ezinokuhambelana kakuhle. Ngokuthambisa okugqwesileyo, ukufuma, ukusasazeka, ukunamathela, kunokusetyenziswa njenge-arhente ye-antistatic kunye ne-ejenti yokuthambisa, njl., kwizinto zokuthambisa, amayeza, ifayibha yemichiza, irabha, iiplastiki, iphepha, ipeyinti, i-electroplating, izibulali zinambuzane, ukusetyenzwa kwesinyithi kunye namashishini okulungisa ukutya. unoluhlu olubanzi kakhulu lwezicelo.

Usetyenziso oluphambili

I-Polyethylene glycol kunye ne-polyethylene glycol fatty acid ester zisetyenziswa ngokubanzi kwishishini lezinto zokuthambisa kunye neshishini loxubo mayeza. Ngenxa yokuba i-polyethylene glycol ineempawu ezininzi ezintle: ukunyibilika kwamanzi, ukungaguquguquki, inertia ye-physiological, ubumnene, ukuthambisa kunye nokwenza ulusu lube manzi, luthambile, lumnandi emva kokusetyenziswa. I-Polyethylene glycol enamabakala ahlukeneyo obunzima bemolekyuli inokukhethwa ukutshintsha i-viscosity, i-hygroscopicity kunye nesakhiwo semveliso. I-molecular weight polyethylene glycol ephantsi (uMnu< 2000) Ifanelekile ukusetyenziswa njenge-agent emanzi kunye nomlawuli ohambelanayo, osetyenziswe kwi-creams, i-lotions, i-toothpastes kunye ne-shaving creams, njl., nazo zifanelekile kwiimveliso zokunakekelwa kweenwele ezingahlanjwanga, ukunika iinwele ukukhanya kwe-filamentous. High molecular weight polyethylene glycol (Mr> 2000) Kwilipstick, intonga yokukhupha ivumba, isepha, isepha yokucheba, isiseko kunye nezithambiso zobuhle. Kwizinto zokucoca, i-polyethylene glycol iphinda isetyenziswe njenge-agent yokumisa kunye ne-thickener. Kumashishini amayeza, isetyenziswe njengesiseko se-ointments, i-emulsions, i-ointments, i-lotions kunye ne-suppositories.

I-Polyethylene Glycol 4000 isetyenziswa ngokubanzi kwiindidi zamalungiselelo amayeza, njenge-injectable, i-topical, i-ocular, i-oral, kunye namalungiselelo e-rectal. Umgangatho oqinileyo we-polyethylene glycol unokongezwa kwi-polyethylene glycol yolwelo ukulungelelanisa i-viscosity ye-ointment yendawo; Umxube we-Polyethylene glycol ungasetyenziswa njenge-suppository substrate. Isisombululo se-aqueous se-polyethylene glycol singasetyenziselwa uncedo lokumisa okanye ukulungelelanisa i-viscosity yeminye imidiya yokumiswa. Ukudibanisa i-polyethylene glycol kunye nezinye i-emulsifiers zandisa ukuzinza kwe-emulsion. Ukongeza, i-polyethylene glycol iphinda isetyenziswe njenge-ejenti yokugqoka ifilimu, i-lubricant yethebhulethi, izinto ezikhutshwayo ezilawulwayo, njl.
