Ibicuruzwa
Propylene Glycol (PG) 99.5%, 99.9% USP Icyiciro / CAS No.: 57-55-6
Ibisobanuro ku bicuruzwa
Yakozwe ku rugero runini cyane cyane kubyara polymers. Mu Muryango w’ubumwe bw’ibihugu by’Uburayi, ifite E-nimero E1520 yo gusaba ibiryo. Ku mavuta yo kwisiga na farumasi, umubare ni E490. Propylene glycol nayo iboneka muri propylene glycol alginate, izwi nka E405. Propylene glycol nuruvange arirwo GRAS (rusanzwe izwi nkumutekano) nubuyobozi bw’ibiribwa n’ibiyobyabwenge muri Amerika munsi ya 21 CFR x184.1666, kandi byemejwe na FDA kugirango ikoreshwe nk'inyongeramusaruro itaziguye. Propylene glycol iremewe kandi ikoreshwa nk'imodoka yo mu rwego rwo hejuru, mu kanwa, ndetse no mu miti imwe n'imwe itegura imiti muri Amerika no mu Burayi.

Mu miti ya farumasi, MEA ikoreshwa cyane cyane muri buffer cyangwa gutegura emulisiyo. MEA irashobora gukoreshwa nkigenzura rya pH mu kwisiga.
Ninshinge sclerosant nkuburyo bwo kuvura indwara ya hemorroide yibimenyetso. Miliyoni 2-5 za oleate ya Ethanolamine irashobora guterwa muri mucosa hejuru ya hemorroide kugirango itere ibisebe no gutobora neza bityo birinda indwara ya hemorroide kumanuka mu muyoboro wa anal.

Uruvange rimwe na rimwe rwitwa (alpha) α-propylene glycol kugirango rutandukane na isomer propane-1,3-diol, izwi nka (beta) β-propylene glycol. Propylene glycol ni chiral. Ibikorwa byubucuruzi mubisanzwe ukoresha ubwoko. S-isomer ikorwa n'inzira y'ibinyabuzima.
1,2-Propanediol ni ibikoresho byingenzi bya polyester idahagije, resin epoxy resin, polyurethane resin, plasitike, na surfactant. Amafaranga yakoreshejwe muri kariya gace agera kuri 45% yikoreshwa rya propylene glycol. Irakoreshwa cyane mubitambaro byo hejuru hamwe na plastiki ishimangirwa. 1,2-propanediol ifite ubukonje bwiza na hygroscopique, kandi ikoreshwa cyane nka agent ya hygroscopique, antifreeze agent, lubricant na solvent mu biribwa, imiti n’amavuta yo kwisiga. Mu nganda z’ibiribwa, 1,2-propanediol ifata aside irike ikora poroteyine glycol fatty acide, ikoreshwa cyane nka emulisiferi y ibiribwa; 1,2-propanediol ni umusemburo mwiza kubirungo na pigment. Bitewe n'uburozi buke, ikoreshwa nk'umuti uhumura ibirungo hamwe n'ibara ry'ibiryo mu nganda y'ibiribwa. 1 ,, 2-Propanediol isanzwe ikoreshwa nkigishishwa, cyoroshya kandi cyoroshye mugukora amavuta atandukanye hamwe namavuta atandukanye munganda zimiti, kandi nkigisubizo cyo kuvanga imiti, imiti igabanya ubukana, amavuta, vitamine, penisiline, nibindi muri farumasi. inganda. Kuberako propylene glycol ifite kutumvikana neza nibirungo bitandukanye, ikoreshwa kandi nk'umuti woroshye kandi woroshye wo kwisiga. 1,2-Propanediol ikoreshwa kandi nk'amazi meza yo kunywa itabi, imiti igabanya ubukana, ibikoresho byo gutunganya ibiryo amavuta hamwe na solvent kugirango irangire ibiryo. Ibisubizo byamazi ya 1,2-propanediol ningirakamaro ya antifreeze. Ikoreshwa kandi nk'umuti woza itabi, imiti igabanya ubukana, imiti yera imbuto, antifreeze hamwe nogutwara ubushyuhe, nibindi.
