Hydroxypropyl methylcellulose (HPMC, Hydroxypropyl Methylcellulose) ninyongeramusaruro myinshi ikoreshwa cyane mubicuruzwa byita kumuntu, cyane cyane kubera imiterere myiza yubushuhe. Nkuko abaguzi b'iki gihe bitondera cyane ubuzima bwuruhu no guhumurizwa, imikorere yubushuhe yabaye imwe mumikorere yibicuruzwa byuruhu. HPMC ni polymeriki ya selilose ishingiye kuri polymer yongerera cyane ubushobozi bwamazi yibicuruzwa byumuntu ku giti cye.
1.Imiterere ya fiziki na chimique ya HPMC
HPMC ni polymer-eruber polymer ikomoka kuri selile ifite imiterere yihariye ya molekuline yitsinda rya hydrophilique (nka hydroxyl na methyl groupe) hamwe na hydrophobique (nka groupe propoxy). Iyi miterere ya amphiphilic ituma HPMC yakira kandi igafunga ubuhehere, bityo igakora firime ikingira uruhu kandi igabanya amazi. HPMC irashobora gukora geles nziza kandi itajegajega kandi ikagaragaza uburyo bwiza bwo gukemura no gukora firime mubushyuhe butandukanye.
2. Ingaruka ziterwa na HPMC zigaragarira cyane cyane mubice bikurikira:
Ubushobozi bwo gufunga amazi: Nkumukozi ukora firime, HPMC irashobora gukora firime imwe, ihumeka hejuru yuruhu kugirango ikumire amazi. Iyi nzitizi yumubiri ntabwo ifunga neza ubuhehere imbere yuruhu gusa, ahubwo irinda umwuka wumye mubidukikije hanze kwangirika uruhu, bityo bikongerera ingaruka nziza.
Kuzamura ibicuruzwa no guhindagurika: Imiterere ya polymer ya HPMC itanga imbaraga zikomeye zo kubyimba, zishobora kunoza ubwiza no kumva ibicuruzwa byita kumuntu. Iki gikorwa cyo kubyimba cyemerera ibicuruzwa gupfukirana neza uruhu rwuruhu iyo rushyizwe mubikorwa, bigatanga uburyo bwiza bwo gutanga no kugumana. Muri icyo gihe, binatezimbere ituze ryibicuruzwa kandi bikarinda ubushuhe nibintu bikora birimo gutandukana cyangwa gutura.
Kurekura kwigana ibintu bifatika: HPMC irashobora kugenzura igipimo cyo kurekura ibintu bikora binyuze mumurongo wa gel, ukareba ko ibyo bikoresho bishobora gukomeza gukora hejuru yuruhu igihe kirekire. Uyu mutungo-wo kurekura ufasha gutanga hydrasiyo ndende, cyane cyane iyo uruhu rwahuye nikirere cyumwanya mugihe kinini.
3. Gukoresha HPMC mubicuruzwa bitandukanye byita kubantu
Amavuta yo kwisiga
HPMC nikintu gisanzwe kibyibushye kandi kigakora firime mumavuta yo kwisiga. Ntabwo itanga gusa ibicuruzwa byifuzwa gusa, inatezimbere imiterere yayo. Imiterere yihariye ya HPMC ifasha kunoza imikorere yuruhu rwimikorere yubushuhe, bigatuma uruhu rwumva rworoshye kandi ntirusize amavuta nyuma yo kurukoresha. Muri icyo gihe, imiterere ya firime ifasha kugabanya gutakaza ubushuhe hejuru yuruhu no kongera ubushobozi bwo gufunga ibicuruzwa.
Kwoza ibicuruzwa
Mu kweza ibicuruzwa, HPMC ntabwo ikora gusa nkigikoresho cyo kubyimba kugirango ifashe kunoza imiterere, ahubwo inarinda inzitizi y’uruhu mugihe cyoza. Mubihe bisanzwe, ibicuruzwa bisukura bikunda gutuma uruhu rutakaza amavuta nubushuhe kuko birimo ibintu byangiza. Ariko, kongeramo HPMC birashobora kugabanya umuvuduko wamazi kandi bikarinda uruhu gukama no gukomera nyuma yo kweza.
izuba
Ibicuruzwa byizuba bikenera gukora hejuru yuruhu igihe kirekire, kubwibyo bitanga amazi ni ngombwa cyane. HPMC ntishobora gusa kunoza imiterere n’umutekano w’ibicuruzwa bituruka ku zuba, ariko kandi ifasha gutinda guhumeka amazi no kugumana ubushyuhe bw’uruhu, bityo ikirinda gutakaza ubushuhe buterwa no guhura na ultraviolet hamwe n’ibidukikije byumye.
Mask yo mu maso
HPMC ikoreshwa cyane mugukwirakwiza masike yo mumaso. Bitewe nubushobozi buhebuje bwo gukora firime hamwe nubwiza bwamazi, HPMC irashobora gufasha ibicuruzwa byo mumaso byo mumaso gukora ibidukikije bifunze neza iyo bishyizwe mumaso, bigatuma uruhu rwakira neza intungamubiri muri rusange. Imiterere irekura-irekura ya HPMC iremeza kandi ko ibikoresho bikora bishobora guhora bisohoka mugihe cyo gusaba, bikazamura ingaruka rusange yubushuhe bwa mask.
ibicuruzwa byita kumisatsi
HPMC yerekanye kandi ingaruka nziza zitanga umusaruro mubicuruzwa byita kumisatsi. Mugihe wongeyeho HPMC kumisatsi, masike yimisatsi nibindi bicuruzwa, firime irashobora gukingira hejuru yumusatsi, bikagabanya gutakaza ubushuhe no kongera ubworoherane nubworoherane bwimisatsi. Mubyongeyeho, HPMC irashobora kunoza imiterere yibicuruzwa, byoroshye gukwirakwira neza mugihe cyo kuyikoresha.
4. Gukorana hagati ya HPMC nibindi bikoresho bitanga amazi
Ubusanzwe HPMC ikoreshwa ifatanije nibindi bikoresho bitanga amazi kugirango ibone ingaruka nziza. Kurugero, ibintu bya kijyambere bitanga amazi nka sodium hyaluronate na glycerine byahujwe na HPMC kugirango byongere ubushobozi bwuruhu rwuruhu ndetse no gufunga ubuhehere binyuze mubikorwa bya firime ya HPMC. Byongeye kandi, iyo HPMC ikoreshwa ifatanije na polysaccharide cyangwa proteyine, irashobora kandi gutanga imirire yinyongera no kurinda ibicuruzwa.
Kwiyongera kwa HPMC ntabwo bitezimbere gusa imiterere yubushuhe bwibicuruzwa, ahubwo binanonosora imiterere, ibyiyumvo no guhagarara neza kubicuruzwa binyuze mubyibushye no gukora firime, bikanoza cyane kwemerwa kwabaguzi. Mugushushanya kwa formula, muguhindura ingano ya HPMC yongeweho hamwe nikigereranyo cyibindi bikoresho, ibisubizo byabugenewe byakozwe neza birashobora gutangwa kubwoko butandukanye bwuruhu numusatsi.
5. Umutekano n’umutekano
Nkibikoresho byo kwisiga bikoreshwa cyane, HPMC ifite biocompatibilité numutekano. HPMC ifatwa nka hypoallergenic kandi idafite imiti ikaze, bigatuma ikoreshwa muburyo bwuruhu rwose, ndetse nuruhu rworoshye. Gukoresha igihe kirekire ibicuruzwa birimo HPMC ntabwo bizatera ingaruka mbi kuruhu. Mubyongeyeho, HPMC ifite imiti ihamye kandi yumubiri kandi irashobora gukomeza imikorere yayo hejuru ya pH nubushyuhe.
Ikoreshwa rya HPMC mubicuruzwa byita kumuntu byakuruye abantu benshi cyane kubera imikorere myiza yubushuhe hamwe nibindi bikorwa byinshi. Ntabwo ifunga gusa ubuhehere binyuze mu gukora firime, ahubwo inatezimbere ibicuruzwa, guhindagurika no gutuza, bigatuma ibicuruzwa byita kumuntu bigera kuburinganire hagati yingaruka ningaruka ziterwa nubushuhe. Hamwe no guhanga udushya no guteza imbere ibicuruzwa byita ku ruhu, porogaramu zitandukanye za HPMC zitanga amahirwe menshi kubashinzwe gukora kandi bizana uburambe kandi bwiza bwogukoresha neza kubaguzi.
