Hydroxypropyl methylcellulose (HPMC) ikomoka kuri selile kandi ikoreshwa cyane mu nganda zitandukanye kubera imiterere yihariye. Ni selile ya nonionic selulose yabonetse muguhindura molekile ya selile isanzwe hamwe na oxyde ya propylene na methyl chloride. Ubusanzwe HPMC igurishwa muburyo bwa poro hanyuma igashonga mumazi kugirango ibe igisubizo kiboneye, kitagira ibara, cyiza.
Ibintu shingiro bya HPMC biratandukanye kandi bifite akamaro mubikorwa byinshi. Bimwe mubintu byamenyekanye cyane harimo imyitwarire yo gufata amazi, kubyimba no gukora firime. HPMC nayo ni uruganda ruhamye cyane rutangirika byoroshye kubera ubushyuhe cyangwa gusaza.
Imwe mu miterere yingenzi ya HPMC nubushobozi bwayo bwo kugumana molekile zamazi. Ibikoresho byayo bigumana amazi nibyingenzi mubikorwa bitandukanye, cyane cyane mubwubatsi n'ibikoresho byo kubaka. Iyo wongeyeho sima cyangwa ibindi bikoresho byubaka, HPMC irashobora kugabanya umuvuduko wo kumisha, ikayirinda kwuma cyane kandi ikavunika vuba. Mugumana molekules zamazi, HPMC iteza imbere gukira no kuyobora neza, bityo bikongerera imbaraga nigihe kirekire cyibicuruzwa byarangiye.
Undi mutungo wingenzi wa HPMC nubushobozi bwawo bwo kubyimba. HPMC yongerera amazi gukora umuyoboro wa gel iyo ushonga mumazi. Umubyimba ni ingenzi mu nganda nyinshi zisaba urwego rwihariye rwibicuruzwa. Kurugero, mu nganda zibiribwa, HPMC ikoreshwa nkibintu byiyongera mu masosi no kwambara kugirango tunoze imiterere kandi ihamye. Mu nganda zimiti, HPMC ikoreshwa nkumuhuza mugutegura ibinini kugirango itezimbere ubumwe hamwe no gusenyuka.
HPMC nayo ni umukozi mwiza wo gukora firime. Iyo ushonga mumazi, irashobora gukora firime yoroheje, ibonerana, yoroheje. Ubushobozi bwo gukora firime ya HPMC butuma biba ingirakamaro muburyo bwo gukora dosiye zikomeye zo mu kanwa hamwe na transdermal. Imiterere ya firime ya HPMC ifasha kunoza iyinjizwa ryibiyobyabwenge itanga inzitizi hagati yibiyobyabwenge nibidukikije.
Usibye kubika amazi, kubyimba no gukora firime, HPMC ifite indi mico yifuzwa. Kurugero, HPMC yerekana imiterere myiza ya rheologiya, bivuze ko ishobora gukoreshwa mugucunga imigendekere nubwiza bwamazi. Ubushobozi bwayo buhambaye butuma buhuza ibice hamwe nubutaka mubisubizo, bikagira akamaro muburyo bwo guhagarika.
HPMC nikintu gihamye cyane hamwe nubushyuhe bwiza no kurwanya gusaza. Ntabwo ikora nibindi bintu, bigatuma ihuza nibikoresho byinshi bitandukanye. Guhagarara kwayo kandi bituma biba byiza gukoreshwa mubicuruzwa bisaba igihe kirekire.
HPMC ikoreshwa mu nganda nyinshi, zirimo ubwubatsi, imiti, ibicuruzwa byita ku muntu, ibiryo ndetse no kwisiga. Mu bwubatsi, ikoreshwa nkibikoresho bigumana amazi muri sima, beto na minisiteri kugirango bitezimbere akazi no kugena igihe. Muri farumasi, HPMC ikoreshwa nkibikoresho, bidahwitse, kandi bigenzurwa nogusohora ibinini. Irakoreshwa kandi nkibihindura viscosity mubisubizo byamaso.
Mu nganda zita ku muntu ku giti cye, HPMC ikoreshwa nk'umubyimba mwinshi muri shampo, amavuta yo kwisiga hamwe nibindi bicuruzwa byiza kugirango utezimbere ubwiza nubwiza. Irakoreshwa kandi nk'umukozi ukora firime mu kwisiga kugirango afashe kunoza no gukwirakwiza pigment no kwirinda guhuzagurika.
Mu nganda zibiribwa, HPMC ikoreshwa nkibyimbye, emulisiferi na stabilisateur mubicuruzwa nkibikomoka ku mata, isupu n'ibinyobwa. HPMC ikoreshwa kandi nk'igikoresho cyo gutwikira no gukora firime mu mbuto, imboga na bombo.
HPMC nuruvange rwinshi rufite ibintu byinshi byifuzwa nko kubika amazi, kubyimba, no gukora firime. Bitewe nimiterere itandukanye, ikoreshwa cyane mubikorwa bitandukanye, harimo ubwubatsi, imiti, ibicuruzwa byita kumuntu, ibiryo na cosmetike. HPMC nuruvange ruhamye cyane rutitabira nibindi bikoresho, bigatuma bihuza nibicuruzwa byinshi bitandukanye. Kubwibyo, HPMC ifite uburyo bwinshi bushobora gukoreshwa hamwe nicyerekezo kinini mubikorwa bitandukanye.
