Hydroxypropyl Methylcellulose (HPMC) ni polymer ikoreshwa cyane mu nganda zitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi. Kimwe mu bintu by'ingenzi bikoreshwa ni ugukemura, cyane cyane mu mazi akonje. Iyi ngingo yibanze kumyitwarire ya HPMC mumazi akonje, ishakisha imiterere yayo, ibintu bigira ingaruka, uburyo bwo kongera imbaraga, hamwe nibisabwa.
Hydroxypropyl Methylcellulose (HPMC) ni igice cya sintetike ya polymer ikomoka kuri selile. Ikoreshwa cyane mu nganda zitandukanye kubera imiterere yihariye, harimo kubyimba, guhambira, gukora firime, hamwe nubushobozi bwo gufata amazi. Kimwe mu bintu by'ingenzi bigira ingaruka ku mikorere yacyo ni ugukemuka kwayo, cyane cyane mu mazi akonje. Gusobanukirwa imyitwarire ya HPMC mumazi akonje ningirakamaro mugutezimbere imikoreshereze yayo mubice bitandukanye.
1.Umutungo wa HPMC
HPMC yerekana imiterere ya amphiphilic bitewe nuko hariho amatsinda ya hydrophobique methyl hamwe na hydrophilique hydroxypropyl. Iyi miterere ya amphifilike ituma HPMC ikorana na molekile zamazi no gukora ibisubizo bihamye. Ubushobozi bwa HPMC buterwa nibintu byinshi, harimo uburemere bwa molekile, urugero rwo gusimburwa, nubushyuhe.
2.Ubushobozi bwa HPMC mumazi akonje
HPMC yerekana imbaraga nke mumazi akonje ugereranije namazi ashyushye. Ubushobozi bwa HPMC mumazi akonje buterwa nibintu nkurwego rwo gusimbuza, uburemere bwa molekile, ingano yingingo, hamwe no kuba hari ibindi bisubizo. Mubisanzwe, uburemere buke bwa molekuline hamwe nurwego rwo hejuru rwo gusimbuza byongera imbaraga za HPMC mumazi akonje.
3.Ibintu bigira uruhare mubisubizo
Ibintu byinshi bigira ingaruka kumyuka ya HPMC mumazi akonje, harimo:
Uburemere bwa molekuline: Uburemere buke bwa molekuline HPMC ikunda gushonga byoroshye mumazi akonje kubera kwiyongera kwiminyururu.
Impamyabumenyi yo gusimburana: Urwego rwo hejuru rwo gusimbuza hydroxypropyl hamwe nitsinda ryimikorere ya mikorobe itezimbere imbaraga za HPMC mukongera hydrophilicity.
Ingano ya Particle: Ingano ntoya yorohereza HPMC mumazi akonje.
Ubushyuhe: Amazi akonje agabanya ingufu za kinetic ya molekile, bigatuma idakora neza mugucamo imiyoboro ihuza imiyoboro, bityo bikagabanya imbaraga za HPMC.
4.Uburyo bwo Kongera Ubushobozi
Uburyo butandukanye burashobora kongera imbaraga za HPMC mumazi akonje, harimo:
Imbere-hydrasiyo: Mbere yo gushira HPMC mumazi akonje mbere yo kuyongera kuri formulaire irashobora kunoza imikoreshereze no gukemuka.
Kugabanya Ingano Yibice: Gusya cyangwa micronisiyonike ya HPMC irashobora kongera ubuso bwayo, bigatera gusenyuka vuba.
Guhindura imiti: Guhindura imiterere yimiti ya HPMC binyuze muri derivatisation irashobora kunoza imbaraga zayo mumazi akonje.
Solubilizers: Kwiyongera kumashanyarazi nka surfactants cyangwa co-solvents birashobora kongera imbaraga za HPMC mumazi akonje.
5.Ibisabwa bya HPMC mumazi akonje
Nubwo ifite ubushobozi buke mu mazi akonje, HPMC isanga uburyo butandukanye muburyo busaba amazi akonje. Porogaramu zimwe zisanzwe zirimo:
Imiti ya farumasi: HPMC ikoreshwa mububiko bwa tableti, imiti irekura-irekura, hamwe nibinini byangiza umunwa bisaba amazi akonje kubuyobozi.
Inganda zikora ibiribwa: HPMC ikoreshwa mubicuruzwa byibiribwa nkibinyobwa byihuse, ibikoni, nibikomoka ku mata kugirango bibyibushye kandi byera mumazi akonje.
Amavuta yo kwisiga: HPMC yinjijwe muburyo bwo kwisiga nka cream, amavuta yo kwisiga, hamwe na geles bisaba gukwirakwiza amazi akonje kugirango byoroshye gukoreshwa.
Ubwubatsi: Mubikoresho byubwubatsi nka minisiteri, grout, hamwe na simaitima, HPMC ikoreshwa nkibikoresho bigumana amazi, bisaba gukonjesha amazi akonje kugirango bikwirakwizwe neza.
Mu gusoza, gukomera kwa HPMC mumazi akonje bigira uruhare runini mubikorwa byayo mubikorwa bitandukanye. Mugihe HPMC yerekana ubushobozi buke mumazi akonje ugereranije namazi ashyushye, imitungo yayo irashobora gutezimbere binyuze mubintu nkuburemere bwa molekile, urugero rwo gusimbuza, nubunini buke. Gusobanukirwa nibintu bigira ingaruka kumashanyarazi ya HPMC mumazi akonje ningirakamaro mugutegura ibicuruzwa byiza no kunoza imikorere yabyo mubikorwa bitandukanye.
