Isicelo Nezakhiwo ze-HPMC

IHydroxypropyl Methyl Cellulose (HPMC) iyi-ether ye-cellulose encibilikayo engancibilikiyo emanzini. Ngenxa yezici zayo ezinhle kakhulu, njengokuqina, ukumiswa, inhlanganisela, i-emulsification kanye nokwakheka kwe-membrane, isibe yingxenye ethandwayo ekusetshenzisweni kwezimboni ezihlukahlukene. Isicelo kanye nezici ze-HPMC kuzoxoxwa ngakho ngezansi.

Ukusetshenziswa kwe-HPMC:

Imboni yokudla: I-HPMC isetshenziswa kabanzi embonini yokudla, isetshenziswa njenge-ejenti yokuqina, i-emulsifier kanye ne-stabilizer. Isetshenziselwa imikhiqizo efana no-ayisikhilimu, izinongo, izinongo kanye nokudla okubhakiwe ukuthuthukisa ukuthungwa nokuvumelana.

Imboni yezemithi: I-HPMC isetshenziswa njenge-ejenti yokuqina, ingcina nokuhlakazeka embonini yezemithi. Ibuye isetshenziselwe ukulungisa ama-capsules namaphilisi.

Imboni yezokwakha: I-HPMC isetshenziswa njenge-ejenti yokuqukethwe kwamanzi, i-ejenti yokuqina nokunamathela embonini yezokwakha. Ithuthukisa ukucutshungulwa kanye nokuvumelana kwezinto eziyisisekelo zikasimende futhi kusiza ukunciphisa ukuqhekeka nokufinyela.

Imboni yezimonyo: I-HPMC isetshenziswa njenge-ejenti ejiyile, i-emulsifier kanye nefomula yolwelwesi embonini yezimonyo. Ngenxa yokuthi ingathuthukisa i-viscosity nokuzinza, yizithako ezithandwayo ze-shampoo, lotion kanye nokhilimu.

Izici ze-HPMC:

Ukunyibilika: I-HPMC iyancibilika emanzini abandayo, kodwa inwebeka emanzini ashisayo ukuze yakhe ijeli. Lesi sici siyenza ikwazi ukujiya futhi izinze imikhiqizo ehlukahlukene.

I-Viscosity: I-HPMC iyinto enenduku ephezulu. I-viscosity yayo incike ezingeni lokushintshwa (DS) kanye nesisindo samangqamuzana e-fibrin ether. I-DS ephezulu ne-MW HPMC ine-viscosity ephezulu.

Ukwakheka kwe-Membrane: I-HPMC inezici ezinhle kakhulu zokwakheka kwe-membrane, ezingakha ulwelwesi olucacile futhi oluguquguqukayo. Lesi sici sisetshenziselwa ukulungisa ama-coatings, ama-adhesives namafilimu embonini yezemithi nokudla.

Ukuzinza: I-HPMC iqinisa inani le-pH elibanzi futhi ayihlangani nezinye izingxenye. Iphinde izinzile ekushiseni nasekukhanyeni.

Ekuphetheni:

Ngamafuphi, i-HPMC iyincenye enemisebenzi eminingi futhi inezinhlelo zokusebenza eziningi ezimbonini ezihlukahlukene. Izici zayo ezinhle kakhulu, ezifana ne-solubility, i-viscosity, ukwakheka kwe-membrane nokuzinza, okwenza kube yisinqumo esithandwayo emikhiqizweni eminingi. I-HPMC iyimpahla ephephile nengenabo ubuthi engasetshenziselwa ukudla, imithi, izakhiwo nezimonyo. Ezimbonini ezihlukene, isidingo se-HPMC siyakhula, okufakazela ukuba wusizo nokusebenza kwayo.
