Iimveliso
Propylene Glycol (PG) 99.5%, 99.9% USP Grade / CAS No.: 57-55-6
Ingcaciso yeMveliso
Iveliswa kwinqanaba elikhulu ngokuyinhloko ukuveliswa kweepolymers. Kwi-European Union, inenombolo ye-E1520 yezicelo zokutya. Kwizinto zokuthambisa kunye ne-pharmacology, inani ngu-E490. Ipropylene glycol nayo ikhona kwipropylene glycol alginate, eyaziwa ngokuba yi-E405. I-Propylene glycol yi-compound eyi-GRAS (eyaziwa ngokubanzi njengekhuselekile) yi-US Food and Drug Administration phantsi kwe-21 CFR x184.1666, kwaye ivunywe yi-FDA yokusetyenziswa okuthile njengesongezo sokutya esingathanga ngqo. Ipropylene glycol ivunyiwe kwaye isetyenziswe njengesithuthi se-topical, ngomlomo, kunye namalungiselelo athile amayeza e-intravenous e-US naseYurophu.

Isicelo
| Ihlala isetyenziswa njenge-excipient kumalungiselelo amaninzi amachiza ukwandisa ukunyibilika kunye nokuzinza kweyeza. |
Ekuqulunqweni kwamayeza, i-MEA isetyenziselwa ngokukodwa ukuphazamisa okanye ukulungiswa kwe-emulsions. I-MEA ingasetyenziswa njengomlawuli we-pH kwizinto zokuthambisa.
Yi-sclerosant etofwayo njengokhetho lonyango lwe-hemorrhoids eneempawu. I-2–5 ml ye-ethanolamine oleate inokutofwa kwi-mucosa kanye ngasentla kwe-hemorrhoids ukuze ibangele izilonda kunye nokulungiswa kwe-mucosal ngaloo ndlela ithintele i-hemorrhoids ukuba ihle iphume kumjelo wangaphambili.
Ikwasisithako ekucoceni ulwelo kwii-windshields zemoto.
Inzuzo
Ikhompawundi ngamanye amaxesha ibizwa ngokuba (alpha) α-propylene glycol ukuyihlula kwi-isomer propane-1,3-diol, eyaziwa ngokuba yi (beta) β-propylene glycol. Ipropylene glycol yi-chiral. Iinkqubo zorhwebo ngokuqhelekileyo zisebenzisa i-racemate. I-S-isomer iveliswa ngeendlela ze-biotechnological.
I-1,2-Propanediol yinto ebalulekileyo ekrwada ye-polyester engaxutywanga, i-epoxy resin, i-polyurethane resin, i-plasticizer, kunye ne-surfactant. Isixa esisetyenziswe kule ndawo malunga ne-45% yokusetyenziswa ngokupheleleyo kwepropylene glycol. Isetyenziswa ngokubanzi kwiingubo ezingaphezulu kunye neeplastiki ezomeleziweyo. I-1,2-propanediol ine-viscosity enhle kunye ne-hygroscopicity, kwaye isetyenziswa ngokubanzi njenge-agent ye-hygroscopic, i-agent ye-antifreeze, i-lubricant kunye ne-solvent kumashishini okutya, amayeza kunye ne-cosmetic. Kwishishini lokutya, i-1,2-propanediol isabela nge-fatty acids ukwenza i-propylene glycol fatty acid esters, esetyenziswa kakhulu njenge-emulsifiers yokutya; I-1,2-propanediol sisinyibilikisi esihle kakhulu se-seasonings kunye ne-pigments. Ngenxa yetyhefu ephantsi, isetyenziswa njengesinyibilikisi kwiziqholo kunye nemibala yokutya kwishishini lokutya. I-1,, i-2-Propanediol isetyenziswa ngokuqhelekileyo njenge-solvent, i-softener kunye ne-excipient ekwenzeni i-ointments ehlukeneyo kunye ne-ointments kwi-industry ye-pharmaceutical industry, kwaye njenge-solvent yokudibanisa i-agent, i-preservatives, i-ointments, iivithamini, i-penicillin, njl. ishishini . Ngenxa yokuba ipropylene glycol ine-miscibility elungileyo kunye neziqholo ezahlukeneyo, ikwasetyenziswa njenge-solvent kunye ne-softener yezithambiso. I-1,2-Propanediol iphinda isetyenziswe njenge-moisturizer yecuba, i-agent ye-antifungal, izixhobo zokulungisa ukutya kwe-lubricant kunye ne-solvent ye-inki zokumakisha ukutya. Izisombululo zamanzi ze-1,2-propanediol ziyi-antifreeze agents ezisebenzayo. Ikwasetyenziswa njenge-agent yokumanzisa icuba, i-antifungal agent, i-preservative yokuvuthwa kweziqhamo, i-antifreeze kunye ne-heater carrier, njl.
