Imikhiqizo
I-Propylene Glycol (PG) 99.5%, 99.9% USP Grade / CAS No.: 57-55-6
Incazelo Yomkhiqizo
Ikhiqizwa ngezinga elikhulu ngokuyinhloko ukukhiqizwa kwama-polymers. E-European Union, ine-E-number E1520 yezicelo zokudla. Okwezimonyo nekhemisi, inombolo ngu-E490. I-Propylene glycol nayo ikhona ku-propylene glycol alginate, eyaziwa ngokuthi i-E405. I-Propylene glycol iyinhlanganisela eyi-GRAS (ngokuvamile eqashelwa njengephephile) yi-US Food and Drug Administration ngaphansi kokungu-21 CFR x184.1666, futhi ivunyelwa yi-FDA ukuze isetshenziswe okuthile njengesithako sokudla esingaqondile. I-Propylene glycol ivunyelwe futhi isetshenziswe njengemoto yokulungiswa kwemithi ye-topical, yomlomo, kanye ne-intravenous e-US naseYurophu.

Isicelo
| Ivame ukusetshenziswa njenge-excipient emalungiselelweni amaningi emithi ukuze kwandiswe ukuncibilika nokuzinza komuthi. |
Ekwakhekeni kwemithi, i-MEA isetshenziselwa ngokuyinhloko ukuvimbela noma ukulungisa ama-emulsions. I-MEA ingasetshenziswa njengesilawuli se-pH ezimonyoni.
Kuyi-sclerosant ejovayo njengendlela yokwelapha yama-hemorrhoids anezimpawu. U-2–5 ml we-ethanolamine oleate ungajovwa ku-mucosa ngenhla nje kwama-hemorrhoids ukuze kubangele izilonda kanye nokuqiniswa kwe-mucosal ngaleyo ndlela kuvimbele ama-hemorrhoids ukuthi ehle ngaphandle komsele wangemuva.
Kuphinde kube isithako ekuhlanzeni uketshezi lwama-windshields emoto.
Inzuzo
Inhlanganisela ngezinye izikhathi ibizwa ngokuthi (alpha) α-propylene glycol ukuyihlukanisa ne-isomer propane-1,3-diol, eyaziwa ngokuthi (beta) β-propylene glycol. I-Propylene glycol iyi-chiral. Izinqubo zezentengiso ngokuvamile zisebenzisa i-racemate. I-S-isomer ikhiqizwa imizila ye-biotechnological.
I-1,2-Propanediol iyimpahla ebalulekile yokusetshenziswa kwe-polyester engagcwalisiwe, i-epoxy resin, i-polyurethane resin, i-plasticizer, ne-surfactant. Inani elisetshenziswe kule ndawo libalelwa ku-45% wesamba esisetshenziswa i-propylene glycol. Isetshenziswa kabanzi ekugqokeni okungaphezulu kanye namapulasitiki aqinisiwe. I-1,2-propanediol ine-viscosity enhle ne-hygroscopicity, futhi isetshenziswa kabanzi njenge-hygroscopic agent, i-antifreeze ejenti, i-lubricant ne-solvent ezimbonini zokudla, ezemithi nezimonyo. Embonini yokudla, i-1,2-propanediol isabela ngama-fatty acids ukwakha i-propylene glycol fatty acid esters, esetshenziswa kakhulu njengama-emulsifiers okudla; I-1,2-propanediol iyi-solvent enhle kakhulu yezinongo nezingulube. Ngenxa yobuthi bayo obuphansi, isetshenziswa njenge-solvent yezinongo nemibala yokudla embonini yokudla. I-1,, 2-Propanediol ivame ukusetshenziswa njenge-solvent, i-softener kanye ne-excipient ekwenzeni amafutha ahlukahlukene namafutha okugcoba embonini yezemithi, futhi njenge-solvent yokuhlanganisa ama-agent, ama-preservatives, amafutha okugcoba, amavithamini, i-penicillin, njll. imboni . Ngenxa yokuthi i-propylene glycol inokuxubeka okuhle nezinongo ezihlukahlukene, iphinde isetshenziswe njengesixazululi nesithambile sezimonyo. I-1,2-Propanediol iphinde isetshenziswe njenge-moisturizer kagwayi, i-ejenti ye-antifungal, i-lubricant yemishini yokucubungula ukudla kanye ne-solvent yeziyinki zokumaka ukudla. Izixazululo ezinamanzi ze-1,2-propanediol zingama-antifreeze agents asebenzayo. Ibuye isetshenziswe njenge-ejenti yokumanzisa ugwayi, i-ejenti ye-antifungal, isilondolozi sokuvuthwa kwezithelo, i-antifreeze kanye nesithwali sokushisa, njll.
