Hōʻike huahana
Hana ʻia ia ma ke ʻano nui no ka hana ʻana i nā polymers. I ka European Union, loaʻa iā ia ka E-helu E1520 no nā noi meaʻai. No ka cosmetics a me ka pharmacology, ʻo ka helu ʻo E490. Aia ka propylene glycol i loko o ka propylene glycol alginate, i kapa ʻia ʻo E405. ʻO ka propylene glycol kahi pūhui ʻo GRAS (ʻike nui ʻia he palekana) e ka US Food and Drug Administration ma lalo o 21 CFR x184.1666, a ua ʻae ʻia hoʻi e ka FDA no kekahi mau hoʻohana ma ke ʻano he mea hoʻohui meaʻai ʻole. Ua ʻae ʻia a hoʻohana ʻia ʻo propylene glycol ma ke ʻano he kaʻa no ke kumuhana, waha, a me kekahi mau lāʻau lapaʻau intravenous ma US a ma ʻEulopa.

Palapala noi
| Hoʻohana maʻamau ia ma ke ʻano he mea hoʻohui i nā māla o nā pena, nā uhi a me nā mea hoʻopili e hoʻomaikaʻi ai i ka nani a me ke kūpaʻa o ka uhi. Hiki ke hoʻohana ʻia e like me ka solvent a me ka emulsifier i ka hana ʻana i nā mea hoʻomaʻemaʻe, nā mea hoʻoneʻe pena a me nā kala. |
I loko o ka pharmaceutical formulations, MEA hoʻohana mua no ka buffering a hoʻomākaukau i nā emulsions. Hiki ke hoʻohana ʻia ka MEA ma ke ʻano he pH regulator i nā mea hoʻonaninani.
He sclerosant injectable ma ke ʻano he koho lapaʻau no nā hemorrhoids symptomatic. Hiki ke hoʻokomo ʻia ka 2-5 ml o ka ethanolamine oleate i loko o ka mucosa ma luna pono o ka hemorrhoids e hoʻoulu ai i ka ʻulaʻula a me ka hoʻoponopono ʻana i ka mucosal no laila e pale ai i ka hemorrhoids mai ka iho ʻana mai ke kahawai anal.
He mea ia no ka hoʻomaʻemaʻe wai no nā pale makani kaʻa.
Pōmaikaʻi
Kapa ʻia ka pūhui i kekahi manawa (alpha) α-propylene glycol e hoʻokaʻawale iā ia mai ka isomer propane-1,3-diol, i kapa ʻia ʻo (beta) β-propylene glycol. He kiral ka propylene glycol. Hoʻohana maʻamau nā kaʻina hana i ka racemate. Hoʻokumu ʻia ka S-isomer e nā ala biotechnological.
ʻO 1,2-Propanediol kahi mea waiwai nui no ka polyester unsaturated, epoxy resin, polyurethane resin, plasticizer, a me ka surfactant. ʻO ka nui i hoʻohana ʻia ma kēia wahi e pili ana i ka 45% o ka pau ʻana o ka propylene glycol. Hoʻohana nui ʻia ia i ka uhi ʻili a me nā plastics i hoʻoikaika ʻia. ʻO 1,2-propanediol ka viscosity maikaʻi a me ka hygroscopicity, a hoʻohana nui ʻia e like me ka hygroscopic agent, antifreeze agent, lubricant a me ka solvent i ka meaʻai, pharmaceutical a me cosmetic. I ka ʻoihana meaʻai, 1,2-propanediol e hana me nā mea momona e hana i ka propylene glycol fatty acid esters, i hoʻohana nui ʻia e like me nā emulsifiers meaʻai; ʻO 1,2-propanediol kahi mea hoʻoheheʻe maikaʻi loa no nā mea ʻala a me nā puaʻa. Ma muli o kona haʻahaʻa haʻahaʻa, hoʻohana ʻia ia i mea hoʻoheheʻe no nā mea ʻala a me ka kala ʻai i ka ʻoihana meaʻai. 1,,2-Propanediol ka mea maʻamau e like me ka mea hoʻoheheʻe, softener a me ka excipient i ka hana ʻana i nā ʻano ʻaila like ʻole a me nā mea ʻala i loko o ka ʻoihana lāʻau lapaʻau, a ma ke ʻano he mea hoʻoheheʻe no ka hui ʻana i nā mea hana, preservatives, ʻaila, nā huaora, penicillin, etc. ʻoihana . No ka maikaʻi o ka propylene glycol me nā mea ʻala like ʻole, hoʻohana ʻia ʻo ia ma ke ʻano he solvent a me ka palupalu no nā mea hoʻonaninani. Hoʻohana ʻia ʻo 1,2-Propanediol e like me ka moisturizer paka, antifungal agent, mea hoʻomaʻamaʻa meaʻai lubricant a me ka solvent no ka ʻai ʻana i nā inika. ʻO nā hoʻonā wai o 1,2-propanediol nā mea hana antifreeze maikaʻi. Hoʻohana ʻia ʻo ia e like me ka mea hoʻomaʻemaʻe paka, ka mea antifungal, ka mālama ʻana i ka hua, ka antifreeze a me ka lawe wela, etc.
