Hydroxypropylmethylcellulose (HPMC) ni polymer yakozwe muguhindura selile naturel. Ifite inganda zitandukanye mubikorwa bya farumasi, ibiryo, amavuta yo kwisiga, nubwubatsi. HPMC ni selile ya selelose idafite imbaraga zoroshye gushonga mumazi kandi irashobora gukora igisubizo kiboneye, kibonerana kiguma gihamye murwego runini rwa pH.
Ibiranga HPMC harimo:
1.
2. Ibintu byiza byo gukora firime: HPMC irashobora gukora firime ibonerana nimbaraga nziza zubukanishi. Ibi bituma ikoreshwa mugukora capsules, coatings nibindi bicuruzwa.
3. Igikorwa cyo hejuru cyane: HPMC ifite imiterere-yubuso ikora, ikemerera gukoreshwa nkibikoresho bitose kandi bigatatanya.
4. Ihinduka ryiza ryumuriro: HPMC ihagaze neza mubushyuhe bwinshi kandi irashobora gukoreshwa mubisabwa bisaba iyi mikorere.
5. Gufatanya neza ku bice bitandukanye: HPMC irashobora guhuza ahantu henshi, bigatuma igira akamaro mukubyara ibifuniko.
Imikoreshereze ya HPMC mu nganda zitandukanye:
1. Iraboneka mubinini, capsules hamwe nibisukari.
2. Ibiryo: HPMC ikoreshwa nkibyimbye, stabilisateur na emulisiferi mubiryo. Irashobora gukoreshwa mubicuruzwa nka ice cream, yogurt hamwe na salade.
3. Amavuta yo kwisiga: HPMC ikoreshwa cyane mumavuta yo kwisiga nkumubyimba, emulifier, hamwe nogukora firime. Irashobora gukoreshwa mubicuruzwa nka cream, amavuta yo kwisiga hamwe na shampo.
4. Ubwubatsi: HPMC nikintu cyingenzi mubikoresho byinshi byubwubatsi nkibikoresho bya tile, plaque ishingiye kuri sima na minisiteri. Ikora nkibikoresho bigumana amazi, itezimbere imikorere, kandi itanga uburyo bwiza bwo kugenzura no kugabanuka.
Umubare w'inganda za HPMC:
1. Kubika amazi: Igipimo cyo gufata amazi ya HPMC nikintu cyingenzi kigena imikorere yacyo nkikibyimbye kandi gifata. Umutungo ufite igipimo cyerekana inganda zingana na 80-100%.
2. Viscosity: Viscosity nikintu cyingenzi muguhitamo HPMC kubikorwa bitandukanye. Inganda zerekana inganda zijimye kuva kuri 5.000 kugeza 150.000 mPa.s.
3. Ibirimo mumatsinda ya Methoxyl: Imikorere ya matsindaxxyl yibigize HPMC igira ingaruka kubikemura, ibishishwa hamwe na bioavailability. Ingano yerekana inganda kubintu biri hagati ya 19% na 30%.
4. Inganda zerekana inganda za hydroxypropyl ziri hagati ya 4% na 12%.
HPMC ni polymer itandukanye hamwe nibikorwa byinshi byinganda. Imiterere yihariye ituma ikoreshwa muburyo bwa farumasi, ibiryo, kwisiga no kubaka. Inganda zerekana ibipimo bitandukanye bifasha muguhitamo icyiciro gikwiye cya HPMC kubisabwa byihariye.
