Hydrexypropropsl hydrolcellse (HPMC) ʻo kahi hui polommer wai i loaʻa i ka hoʻololiʻia e ka hoʻololiʻana i ka chemikina o nā mea kanu kūlohelohe maoli. He kūpono kūpono,ʻo ka paʻa a me ka biocompatibility, a hoʻohana nuiʻia i ka meaʻai, nā lāʻau lapaʻau, nā mea kanu a me nāʻano'ē aʻe. E hoʻopuka i nā mea i piliʻia, nāʻano hana kumukūʻai, nā kumu e hoʻomākaukau ana, nā noi nui, a me nā pono mua a me nā maikaʻi o ka HPMC i ka kiko'ī.
1.ʻO keʻano hoʻohālikelike a me nā waiwai
ʻO keʻano maʻamau o ka HPMC i loaʻa mai i ka cellouse kūlohelohe. Ma luna o kāna kaulahao Moolecular, e hoʻololiʻia kekahi mau pūʻulu Hydroxyl (-HH) e Mithyl Grounds (-CH3) ʻO kānaʻano kiko'ī kiko'ī e hoʻouluʻia e ka mea e hoʻonāukiuki i nā mole cellouse o nā mollulose
Ua pili pū ka palena wai o HPMC e pili ana i ka pae o keʻano o ka huiʻana o ka huiʻana o ka huiʻana a me nā hui hydroxyproopyl a me nā mydroxyproopyl ʻO ka maʻamau,ʻo HPMC i nā hiʻohiʻona aʻe:
ʻO ka waiʻona maikaʻi;
Ka hopena maikaʻi, a me ka neʻe ikaika i ka wela a me ka alkali;
ʻO ka mākaʻikaʻi kiʻekiʻe,ʻoi aku ka hopena ikaika;
Ma muli o kānaʻano chercience, hiki i ka hpmc ke hana i kahi kiʻiʻoniʻoni a loaʻa i kahi hopena i mālamaʻia i nā lāʻau lapaʻau a iʻole nā mea'ē aʻe.

ʻO ka hoʻomākaukauʻana o HPMC i loaʻa i ka hopena o ka eterification i ka hopena o ka cellouse. ʻO Cellulose mua i hanaʻia me ka mloride mitryl chloride (ch3cl) a me hydroxyproopyl chloride (c3h7och2lar i loaʻa i nā huahana a hydrotch. Ke hilinaʻi nei i nā kūlana kūpono (e like me ka mahana, ka manawa kūpono, etc.), keʻano o ka HPMC. ʻO nā hana kūikawā e like me kēia:
Hoʻokuʻuʻia ka cellouse e wehe i nā haumia.
E hana me ka mloride chloride a me ka hydroxyproopsl chloride ma kahi hopena alkaline no ka hopena o ka aihue.
Loaʻa ka huahana HPMC hope ma o ka hoʻokuʻuʻana, Hoʻohui, hoʻomaloʻo a me nā wāwae'ē aʻe.

3.1Palapala Pharmaceutical
I loko o kaʻoihana lāʻau lapaʻau, ua hoʻohana nuiʻiaʻo HPMC ma keʻano he mea hoihoi no nā lāʻau lapaʻau. ʻAʻole ia wale wale e hoʻohanaʻia he pickaner, akā akā hiki ke hoʻohanaʻia e hoʻomākaukau e hoʻomākaukau i ka hoʻomākaukauʻana i ka lā. ʻO kāna mau wai wai maikaʻi loa a me ka bilipetation e hana ai he mea nui i ka hoʻomākaukauʻana o ka lāʻau lapaʻau e like me nā papaʻaina, nā paila, a me nā pā. Nā noi maʻamau e loaʻa:
Hoʻokuʻuʻia ka hoʻoukaʻana o ka lāʻau: hiki ke hoʻokaʻawale i ka HPMC i ke kino a hoʻokuʻu i nā lāʻau lapaʻau, no laila ua hoʻohana pinepineʻia e hoʻomākaukau i nā lāʻau lapaʻau i mālamaʻia.
ʻO ka mea lawe kaʻa kaʻa
Gel: hiki ke hoʻohanaʻiaʻo HPMC e like me ka gel e hoʻomākaukau ai i nāʻano gel e hoʻomākaukau ai i nāʻano o nā lāʻau lapaʻau likeʻole.
3.2ʻO kaʻoihana meaʻai
Ua hoʻohana nuiʻiaʻo HPMC i kaʻoihana meaʻai, ka nui e hoʻomaikaʻi i ka hua'ōlelo o ka meaʻai, hoʻonui i ke ola pale, a hoʻomaikaʻi i ka hana meaʻai. Nā noi maʻamau e loaʻa:
ʻO Skickener a me Stabilizer: Hiki ke hoʻohanaʻiaʻo HPMC e like me kahi mea e like me nā meaʻai e like me keʻano o ka mea kanu.
ʻO ke Kulanui Gilling: Ma kekahi mau meaʻai, hiki ke hoʻohanaʻiaʻo HPMC e like me keʻano he nui e hāʻawi i kahi hopena gel.
Eʻai i ka berena a me nā mea kahiko
3.3 hana kūkulu
Ua hoʻohana nuiʻiaʻo HPMC ma kahi o kahi mea hoʻokele a me ka wai-wai-noho no ka hale kūkulu, e hoʻohana pinepineʻia ma nāʻano hana ma hope:
Hiki iā Morthar: Hiki i ka HPMC ke hoʻonui i ka adhesion, ka nui o ka wai a me ka wai o ka lepo, a hoʻomaikaʻi i ka hana o ka hōʻino.
E hoʻomaikaʻiʻia: hiki iā HPMC ke hoʻomaikaʻi i ka hana kūkuluʻana i ka hana o ka hana a me ka hoʻonuiʻana i kāna hana.
Pena: me ka hoʻohanaʻana i ka hpmc ma ka pena i hiki ke hoʻonui i ka viscosity a me ka paʻa o ke kiʻi, a kōkua i ka mālamaʻana i ke kumu o ka pena pena.
3.4 Nāʻenehana i kōkuaʻia
I nā cosmetics, ua hoʻohana nuiʻiaʻo hpmc ma keʻano he shuckener, emulsifier a me nā mea hana hana, a me nā mea hoʻomaʻemaʻe maikaʻi, a me nā pale maka. Ua loaʻa i kāna mau hana:
Smickener: Hiki i ka HPMC ke hoʻonui i ka viscosity o nā cosmetics a hoʻonui i ka manaʻo o ka hoʻohana.
ʻO Moisturizer: Ua loaʻa iā HPMC maikaʻi i nā waiwai moisturizing a hiki ke kōkua i ka laka i ka waimaka e mālama i kaʻili o kaʻili.
Emulsifier: Hiki i ka HPMC ke kōkua i ka wai a me kaʻailaʻaila e hana i kahi emulsion stable.
4. Loaʻa a me nā hemahema kūpono
4.1 Pono
ʻO ka biocompatibtiboli maikaʻi:ʻo HPMC kahi huahana cedied kūlohelohe kūlohelohe, maʻamau non-dichix a iʻole ka mea maikaʻiʻole i ke kino kanaka, a he biocomopibility maikaʻi.
ʻO kaʻono a me ka antorless
Hoʻohana nuiʻia: Ma muli o kāna mau wai momona wai maikaʻi loa, wīwī a me ka kūpaʻa, ua hoʻohana nuiʻia ka HPMC i nāʻoihana he nui.
4.2 Loaʻa nā hemahema
Loaʻa maikaʻi loa i ka mahana kiʻekiʻe:ʻoiaiʻo HPMC maikaʻi i keʻano he nui, e hoʻomehana i lalo o nā kūlana kiʻekiʻe.
Ka uku kumukūʻai kiʻekiʻe: Hoʻokomoʻia me kekahi mau mea nui nā mea nui kuʻuna,ʻo Hpmc,ʻoi aku ka nui o ka hoʻopukaʻana i kona mau noi.
E like me ka hui pūʻanaʻo PolymerHpmc ua hoʻohana nuiʻia i ka lāʻau lapaʻau, meaʻai,ʻai, kūkulu, nā mea kanu a me nāʻano'ē aʻe ma muli o kona mau wahi wai maikaʻi, biocomopatiblity a me ka paʻa. Me ka hoʻomohalaʻana o kaʻepekema a me kaʻenehana a me ka holomua o ka noiʻana o ka noi, e hoʻonui houʻia kaʻenehana a me nā palapala noi.
