HPMC Hypromellose

Hydroxypropyl Methylcellulose(HPMC), he mea hoʻohui kemika maʻalahi me ke kumu hoʻohālike [C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x, kahi m e hōʻike ana i ke degere o ka hoʻololi ʻana i ka methoxy a ʻo n ka degere o ka hydroxypropoxy. pani. Loaʻa ia mai ka cellulose, kahi polymer maoli i loaʻa mai nā paia o nā mea kanu. ʻAʻohe ʻala o HPMC, ʻono ʻole, a ʻaʻohe mea ʻawaʻawa. Loaʻa iā ia nā ʻano physicochemical like ʻole e like me ka solubility i ka wai, nā waiwai gelation thermal, a me ka hiki ke hana i nā kiʻiʻoniʻoni, e hoʻohana nui ʻia ma nā ʻoihana he nui.

I loko o ka ʻoihana lāʻau lapaʻau, hoʻohana nui ʻia ka HPMC ma ke ʻano he mea kōkua-he mea i hana ʻia ma ka ʻaoʻao o ka mea hana o ka lāʻau lapaʻau, no ke kumu o ka hoʻopaʻa ʻana i ka wā lōʻihi, ka hoʻonui ʻana i nā mea paʻa paʻa i loaʻa nā mea hoʻoikaika ikaika i nā mea liʻiliʻi (pēia i kuhikuhi pinepine ʻia. ma ke ʻano he mea hoʻopiha, diluent, a i ʻole ka mea lawe), a i ʻole e hoʻonui i ka absorption a i ʻole solubility. He mea ʻokoʻa ka HPMC capsules i nā capsules gelatin no nā mea ʻai meaʻai a hoʻohana ʻia i nā ʻano hoʻokuʻu hoʻokuʻu ʻia, e ʻae ana i ka hoʻokuʻu lohi ʻana o kahi lāʻau i ka manawa. Hiki i nā ʻoluʻolu HPMC ke lawelawe ma ke ʻano he viscolyzers e hoʻonui i ka viscosity o nā solution ophthalmic, hoʻomaikaʻi i ka bioadherence, a hoʻolōʻihi i ka manawa noho o nā lāʻau lapaʻau ma ka ʻili ocular.

Ma ka ʻoihana meaʻai, ʻike ʻia ʻo HPMC he mea hoʻohui meaʻai palekana (E464) a lawelawe i nā hana he nui e like me ka emulsifier, thickening agent, a me ka stabilizer. Hoʻohana ʻia ia i ka hana ʻana i nā meaʻai like ʻole e hoʻomaikaʻi i ke ʻano, mālama i ka makū, a hana i nā kiʻiʻoniʻoni ʻai. He waiwai nui ka waiwai gelation thermal o HPMC i nā noi e koi ana i ka gelling i nā mahana kikoʻī, e like me ka meaʻai meaʻai a me nā meaʻai vegan kahi e hiki ai ke pani i ka gelatin. Hāʻawi pū ʻo HPMC i ke ola o ka papa a me ka maikaʻi o nā meaʻai i hoʻomoʻa ʻia, nā kīʻaha, a me nā mea ʻono ma o ka hoʻomalu ʻana i ka crystallization a me ka makū.

Pono ka ʻoihana kūkulu hale mai HPMC i ka hana ʻana i nā mea hale. ʻO kāna mau hoʻohana ʻana e hana ma ke ʻano he mea hoʻopaʻa a paʻa i ka wai i loko o nā mortar, plasters, a me nā uhi, hoʻomaikaʻi i ka hana, hōʻemi i ka hoʻohana ʻana i ka wai, a hoʻolōʻihi i ka manawa hāmama - ka manawa e hoʻohana mau ʻia ai kahi mea. Hoʻonui ka HPMC i nā waiwai o ka hoʻokumu ʻana i ka sima, e hāʻawi ana i ka hoʻopili maikaʻi ʻana, ka pālahalaha ʻana, a me ke kūʻē ʻana i ka sagging.

Ma ka ʻoihana hoʻomaʻemaʻe a me ka ʻoihana mālama pilikino, lawelawe ʻo HPMC ma ke ʻano he mea hana kiʻiʻoniʻoni, emulsifier, a me rheology modifier i nā huahana e like me nā lotions, creams, a me nā lauoho gels. ʻO kona kūlike me nā ʻano ʻili like ʻole a me ka hiki ke hoʻopaʻa i nā emulsion e hoʻonui i ka hana huahana a me ka lōʻihi. ʻO nā waiwai hydration o HPMC he mea makemake ia e mālama i ka ʻili, e kōkua ana i ka mālama ʻana i ka makū a me ka hāʻawi ʻana i ka ʻoluʻolu. I ka hōʻuluʻulu manaʻo, ʻo ka versatility o HPMC e pili ana i nā lāʻau lapaʻau, nā meaʻai, ke kūkulu ʻana, a me nā mea hoʻonaninani, e hōʻike ana i kona koʻikoʻi ma ke ʻano he multifunctional i loko o nā noi like ʻole.
