I-Hydroxypropyl methylcellulose, eyaziwa ngokuba yi-HPMC, i-polymer esetyenziswa ngokubanzi kwiindawo zokutya, amayeza, ukwakhiwa, izimonyo, kunye neemveliso zokhathalelo lomntu.Yindalo ye-cellulose ether eyenziwa ngokuguqulwa kweekhemikhali ze-cellulose, i-polymer yendalo evela kwizityalo.Inkqubo yokuguqulwa ibandakanya ukuqaliswa kwe-hydroxypropyl kunye namaqela e-methyl kwi-molecule ye-cellulose, eguqula iimpawu zayo kwaye iyenze ibe yinto eguquguqukayo yokusetyenziswa kuluhlu olubanzi lwezicelo.
Kukho iintlobo ezininzi ze-HPMC ezifumanekayo kwimarike, nganye ineempawu zayo ezizodwa eziyenza ilungele izicelo ezithile.Kweli nqaku, siza kuxoxa ngeentlobo eziphambili ze-HPMC, iimpawu zabo kunye nokusetyenziswa.
1. HPMC E5
I-HPMC E5 luhlobo lwe-HPMC ene-viscosity ephantsi kwaye ibonakaliswe ngokunamathela kwayo okulungileyo, ukugcinwa kwamanzi kunye neepropati ezityebileyo.Isetyenziswa ngokuqhelekileyo kushishino lokwakha njengesongezo kwiimveliso ezisekelwe kwisamente ukuphucula ukusebenza kwazo, ukugcinwa kwamanzi, kunye namandla okudibanisa.Ikwasetyenziswa ekwenzeni iithayile zeceramic, iimveliso zegypsum, kunye nezinto zokutyabeka.Kwishishini lokutya, kusetyenziswa njengesixhobo sokutyebisa kwiimveliso zobisi, iisosi, kunye neesuphu.
2. HPMC E15
I-HPMC E15 luhlobo lwe-HPMC olune-viscosity ephakathi kwaye luphawulwa ngokugcinwa kwamanzi aphezulu, ukujiya kunye nokusabalalisa iipropati.Isetyenziswa ngokuqhelekileyo njenge-ejenti yokuqina kunye nokuzinzisa kwimveliso yokutya, kunye nakwishishini lamachiza njenge-excipient yokuphucula i-viscosity kunye nokuhambelana kwamachiza.Ikwasetyenziselwa ukuveliswa kwezinto zokuthambisa kunye nemveliso yokunyamekela komntu ukuphucula ukuthungwa kunye nokuzinza.
3. HPMC E50
I-HPMC E50 luhlobo lwe-HPMC ene-viscosity ephezulu kwaye luphawulwa ngokutyeba kwayo okugqwesileyo, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu.Idla ngokusetyenziswa xa kusenziwa izinto zokuhombisa, iipeyinti, nezokuncamathelisa njenge-thickener nebinder.Ikwasetyenziswa kushishino lokutya ukuphucula ukuthungwa kunye nokuzinza kweemveliso ezifana neempahla ezibhakiweyo, itshizi, kunye nenyama egayiweyo.
4. HPMC K4M
I-HPMC K4M luhlobo lwe-HPMC olune-viscosity ephezulu kwaye luphawulwa ngokugqwesa okugqwesileyo kunye neempawu zokuncamathelisa.Idla ngokusetyenziswa kwishishini loxubo mayeza njengoncedo ekuphuculeni izinga lokuchithwa kunye ne-bioavailability yamachiza, kunye nokuguqula iprofayili yokukhululwa kwamachiza.Ikwasetyenziswa kushishino lokutya ukuphucula ukuthungwa kunye nokuzinza kweemveliso ezifana neziselo, amashwamshwam, kunye nezimuncumuncu ezikhenkcezisiweyo.
5. HPMC K100M
I-HPMC K100M luhlobo lwe-HPMC ene-viscosity ephezulu kakhulu kwaye ibonakaliswe ngokugqwesa kwayo okugqwesileyo, ukwenza ifilimu kunye neepropati ezizinzileyo zokukhululwa.Isetyenziswa ngokuqhelekileyo kwishishini loxubo-mayeza njenge-excipient ukuphucula i-bioavailability kunye nokukhululwa okulawulwayo kwamachiza.Ikwasetyenziswa ekuveliseni izinto zokuhombisa, iipeyinti, kunye nezokuncamathelisa ukuphucula ukujiya kwazo kunye neempawu zokuzibophelela.
Ukuqukumbela, i-HPMC yipolymer eguquguqukayo enoluhlu olubanzi lwezicelo kumashishini ahlukeneyo.Iindidi ezahlukeneyo ze-HPMC ezikhoyo kwimarike zenza kube lula ukukhetha eyona ifanelekileyo kwisicelo esithile ngokusekelwe kwiipropati kunye neempawu zayo.Impembelelo entle ye-HPMC kumashishini ahlukeneyo yenze ukuba ibe lukhetho oludumileyo njengolongezelelweyo kwiimveliso ezininzi.
