IHydroxypropyl methylcellulose (HPMC) iphuma kwi cellulose kwaye isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa.I-ether ye-cellulose e-nonionic efunyenwe ngokuguqula i-molecule ye-cellulose yendalo kunye ne-propylene oxide kunye ne-methyl chloride.I-HPMC idla ngokuthengiswa kwifomu yomgubo kwaye inyibilika emanzini ukwenza isisombululo esicacileyo, esingenambala, esibonakalayo.
Iipropati ezisisiseko ze-HPMC zahlukeneyo kwaye ziluncedo kwizicelo ezininzi.Ezinye zeempawu zayo eziphawulekayo ziquka ukuziphatha kokugcinwa kwamanzi, ukuqina kunye neempawu zokwenza ifilimu.I-HPMC ikwayikhompawundi ezinzile kakhulu engawohloki ngokulula ngenxa yobushushu okanye ukuguga.
Enye yezona zinto zibalulekileyo ze-HPMC kukukwazi ukugcina iimolekyuli zamanzi.Iipropati zayo zokugcina amanzi zibalulekile kwiinkqubo ezahlukeneyo, ngakumbi kulwakhiwo kunye nemathiriyeli yokwakha.Xa ifakwe kwisamente okanye ezinye izinto zokwakha, i-HPMC inokucothisa inkqubo yokomisa, ithintele ukuba yome kakhulu kwaye ibe brittle ngokukhawuleza.Ngokugcina iimolekyuli zamanzi, i-HPMC ikhuthaza ukunyangwa okufanelekileyo kunye nokuhanjiswa kwamanzi, ngaloo ndlela inyusa amandla kunye nokuqina kwemveliso egqityiweyo.
Enye ipropathi ebalulekileyo ye-HPMC kukukwazi ukutyeba.I-HPMC ijiya ulwelo ngokwenza uthungelwano lwejeli xa inyibilikiswa emanzini.Ukutyeba kubalulekile kumashishini amaninzi afuna amanqanaba athile e-viscosity yeemveliso.Umzekelo, kwishishini lokutya, i-HPMC isetyenziswa njenge-ejenti etyebisayo kwiisosi kunye nezinxibo zokuphucula ukuthungwa kunye nokungaguquguquki.Kwishishini lamachiza, i-HPMC isetyenziswa njenge-binder kwi-tablet formulations ukuphucula ubumbano lwabo kunye neempawu zokuhlukana.
I-HPMC ikwayi-arhente ebalaseleyo yokwenza ifilim.Xa inyibilika emanzini, inokwenza ifilimu encinci, ebonakalayo, eguquguqukayo.Isakhono sokwenza ifilimu ye-HPMC yenza ukuba ibe sisithako esifanelekileyo sokwenziwa kweefom zedosi yomlomo eqinileyo kunye neepatches ze-transdermal.Iipropati zokwenza ifilim ze-HPMC zinceda ukuphucula ukufunxwa kwechiza ngokubonelela ngomqobo phakathi kwechiza kunye nokusingqongileyo.
Ukongeza ekugcinweni kwamanzi, ukutyeba kunye neepropati zokwenza ifilimu, i-HPMC inezinye izinto ezinqwenelekayo.Umzekelo, HPMC ibonisa iimpawu rheological elungileyo, intsingiselo ingasetyenziswa ukulawula ukuhamba kunye viscosity ulwelo.Umthamo wayo ophezulu wokubopha uvumela ukuba ubophe amaqhekeza kunye ne-sediments kwizisombululo, okwenza kube nempumelelo ekumisweni kokumiswa.
I-HPMC yikhompawundi ezinzile kakhulu enokumelana nobushushu obuhle kunye nokumelana nokuguga.Ayisebenzi kunye nezinye izinto, iyenza ihambelane nezinto ezininzi ezahlukeneyo.Ukuzinza kwayo kuyenza ilungele ukusetyenziswa kwiimveliso ezifuna ixesha elide leshelufu.
I-HPMC isetyenziswa kumashishini amaninzi, kuquka ukwakhiwa, amayeza, iimveliso zokhathalelo lomntu, ukutya kunye nezithambiso.Ekwakhiweni, isetyenziswe njenge-arhente yokugcina amanzi kwi-samente, ikhonkrithi kunye nodaka ukuphucula ukusebenza kunye nokubeka ixesha.Kumachiza, i-HPMC isetyenziswa njenge-binder, i-disintegrant, kunye ne-ejenti yokukhululwa elawulwayo kwi-tablet formulations.Ikwasetyenziswa njenge-viscosity modifier kwizisombululo ze-ophthalmic.
Kwishishini lokhathalelo lomntu, i-HPMC isetyenziswa njengesixhobo sokutyebisa kwiishampu, iiloshini kunye nezinye iimveliso zobuhle ukuphucula ukuthungwa kunye ne-viscosity.Ikwasetyenziswa njengesixhobo sokwenza ifilim kwizithambiso ukunceda ukuphucula ukuhanjiswa kwebala kunye nokuthintela ukuqumba.
Kushishino lokutya, i-HPMC isetyenziswa njenge-thickener, emulsifier and stabilizer kwiimveliso ezifana neemveliso zobisi, isuphu kunye neziselo.I-HPMC ikwasetyenziswa njenge-arhente yokugquma kunye ne-ejenti yokwenza ifilimu kwiziqhamo, imifuno kunye neelekese zokugquma.
I-HPMC yikhompawundi eguquguqukayo eneempawu ezininzi ezinqwenelekayo ezifana nokugcinwa kwamanzi, ukujiya, kunye neempawu zokwenza ifilim.Ngenxa yeempawu zayo ezahlukeneyo, isetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa ukwakhiwa, amayeza, iimveliso zokhathalelo lomntu, ukutya kunye nezithambiso.I-HPMC yikhompawundi ezinzile kakhulu engaphenduliyo kunye nezinye izinto, iyenza ihambelane neemveliso ezininzi ezahlukeneyo.Ke ngoko, i-HPMC inoluhlu olubanzi lwezicelo ezinokubakho kunye namathemba abanzi kumashishini ahlukeneyo.
