Ethylene glycol butyl ether CAS No.112-48-1
Mafotokozedwe Akatundu
Amapangidwa pamlingo waukulu makamaka kuti apange ma polima. Ku European Union, ili ndi E-nambala E1520 yofunsira chakudya. Zodzoladzola ndi pharmacology, nambala ndi E490. Propylene glycol imapezekanso mu propylene glycol alginate, yomwe imadziwika kuti E405. Propylene glycol ndi mankhwala omwe ali GRAS (omwe amadziwika kuti ndi otetezeka) ndi US Food and Drug Administration pansi pa 21 CFR x184.1666, ndipo amavomerezedwanso ndi FDA pa ntchito zina monga chowonjezera cha chakudya chosalunjika. Propylene glycol imavomerezedwa ndikugwiritsidwa ntchito ngati galimoto yopangira mankhwala apakhungu, pakamwa, komanso m'mitsempha ku US ndi ku Europe.

Kugwiritsa ntchito
| Amagwiritsidwa ntchito ngati chowonjezera m'minda ya utoto, zokutira ndi zomatira kuti zithandizire kuwunikira komanso kukhazikika kwa zokutira. Itha kugwiritsidwanso ntchito ngati zosungunulira ndi emulsifier popanga zotsukira, zochotsa utoto ndi utoto. |
Mu mankhwala formulations, MEA ntchito makamaka kwa buffering kapena kukonzekera emulsions. MEA itha kugwiritsidwa ntchito ngati pH regulator mu zodzoladzola.
Ndi jekeseni sclerosant ngati njira mankhwala symptomatic zotupa. 2-5 ml ya ethanolamine oleate akhoza kubayidwa mucosa pamwamba pa zotupa kuti apangitse zilonda ndi zilonda zam'mimba motero kuteteza zotupa kuti zitsike kuchokera ku ngalande ya kumatako.
Ndiwofunikanso pakuyeretsa madzi opangira ma windshields agalimoto.
Ubwino
Pawiri nthawi zina amatchedwa (alpha) α-propylene glycol kuti asiyanitse ndi isomer propane-1,3-diol, yotchedwa (beta) β-propylene glycol. Propylene glycol ndi chiral. Njira zamalonda nthawi zambiri zimagwiritsa ntchito racemate. The S-isomer amapangidwa ndi njira biotechnological.
1,2-Propanediol ndi zofunika zopangira poliyesitala unsaturated, epoxy utomoni, polyurethane utomoni, plasticizer, ndi surfactant. Ndalama zomwe zimagwiritsidwa ntchito m'derali zimakhala pafupifupi 45% ya anthu onse omwe amamwa propylene glycol. Amagwiritsidwa ntchito kwambiri mu zokutira pamwamba ndi mapulasitiki olimbikitsidwa. 1,2-propanediol ali ndi mamasukidwe akayendedwe abwino ndi hygroscopicity, ndipo chimagwiritsidwa ntchito monga hygroscopic wothandizira, antifreeze wothandizira, lubricant ndi zosungunulira mu chakudya, mankhwala ndi zodzikongoletsera mafakitale. Muzakudya, 1,2-propanediol imakhudzidwa ndi mafuta acids kupanga propylene glycol fatty acid esters, yomwe imagwiritsidwa ntchito makamaka ngati emulsifiers chakudya; 1,2-propanediol ndi chosungunulira chabwino kwambiri cha zokometsera ndi utoto. Chifukwa cha kawopsedwe kakang'ono, amagwiritsidwa ntchito ngati zosungunulira zonunkhira ndi mitundu yazakudya m'makampani azakudya. 1,,2-Propanediol amagwiritsidwa ntchito ngati zosungunulira, softener ndi excipient popanga zosiyanasiyana mafuta ndi mafuta makampani mankhwala, ndi monga zosungunulira kwa ankasakaniza wothandizila, zoteteza, mafuta odzola, mavitamini, penicillin, etc. mu mankhwala mankhwala. makampani . Chifukwa propylene glycol ili ndi miscibility yabwino ndi zonunkhira zosiyanasiyana, imagwiritsidwanso ntchito ngati zosungunulira ndi zofewa zodzoladzola. 1,2-Propanediol imagwiritsidwanso ntchito ngati moisturizer ya fodya, antifungal wothandizira, zida zopangira chakudya mafuta ndi zosungunulira za inki zolembera chakudya. Mayankho amadzimadzi a 1,2-propanediol ndi othandizira antifreeze. Amagwiritsidwanso ntchito ngati chonyowetsa fodya, antifungal wothandizira, chosungira chakucha zipatso, antifreeze ndi chonyamulira cha kutentha, etc.
