Hydroxypropyl methylcellulose (HPMC)ni ibisanzwe bikomoka kuri selile hamwe nibisabwa byinshi, cyane cyane mubijyanye na farumasi, amavuta yo kwisiga, ibiryo, nibikoresho byubaka. Ntabwo ari umusemburo, ahubwo ni polymer-eruble polymer ishobora gushonga mumazi igakora igisubizo kiboneye. Ubushobozi bwa AnxinCel®HPMC buterwa numubare numwanya wa methyl na hydroxypropyl insimburangingo.
1. Ibintu shingiro bya hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose iboneka muri methylation na hydroxypropylation ya selile. Cellulose ubwayo ni polyisikaride karemano isanzwe ibaho murukuta rw'ibimera. Imiterere yimiti ya HPMC igizwe ahanini nibice bya glucose, bikaba molekile ndende-ihujwe na β-1,4 glycosidic. Muri ubu buryo bwa molekile, amatsinda amwe ya hydroxyl asimburwa na methyl (-OCH₃) na hydroxypropyl (-C₃H₇OH), bikayiha imbaraga nziza nibindi bintu bifatika ndetse nubumara.
Ubushobozi bwa HPMC bugira ingaruka kumiterere ya molekile kandi mubisanzwe bifite ibintu bikurikira:
Amazi meza: HPMC irashobora gukora igisubizo kiboneka mumazi kandi kigashonga vuba. Gukemura kwayo bifitanye isano rya hafi nubushyuhe bwamazi nuburemere bwa molekuline ya HPMC.
Ubukonje bukabije: Mugihe runaka, igisubizo cya HPMC cyerekana ububobere buke, cyane cyane muburemere buke bwa molekile hamwe no kwibanda cyane.
Ubushyuhe bwumuriro: HPMC ifite ituze ryiza kurwego runaka rwubushyuhe kandi ntabwo byoroshye kubora, bityo ifite ibyiza bimwe mubikorwa byo gutunganya amashyuza.
2. Gukemura ibibazo bya HPMC
HPMC ni ikintu gishobora gushonga amazi, ariko ntigishonga numuti wose. Imyitwarire yayo yo gusesa ifitanye isano na polarite yumuti hamwe nubusabane hagati ya molekile ya solde na molekile ya HPMC.
Amazi: HPMC irashobora gushonga mumazi. Amazi niyo akunze kuboneka cyane, kandi mugihe cyo gusesa, molekile ya AnxinCel®HPMC izakora imigozi ya hydrogène hamwe na molekile zamazi kugirango bigere kumeneka. Urwego rwo guseswa rugira ingaruka kubintu nkuburemere bwa molekuline ya HPMC, urugero rwa methylation na hydroxypropylation, ubushyuhe, nagaciro ka pH kumazi. Mubisanzwe, ibisubizo bya HPMC nibyiza mubidukikije bidafite aho bibogamiye.
Umuti ukungahaye: HPMC ntishobora gukemuka mumashanyarazi menshi, nka alcool, ethers, na hydrocarbone. Ni ukubera ko imiterere ya molekile yayo irimo hydrophilique hydroxyl matsinda na lipofilique methyl na hydroxypropyl. Nubwo ifitanye isano ikomeye n’amazi, ifite aho ihurira n’imyunyu ngugu myinshi.
Amazi ashyushye: Mu mazi ashyushye (ubusanzwe 40 ° C kugeza 70 ° C), HPMC irashonga vuba kandi igisubizo cyashonze kigaragaza ububobere buke. Mugihe ubushyuhe bugenda bwiyongera, umuvuduko wo gushonga no gukomera biziyongera, ariko kubushyuhe bwinshi cyane, ubwiza bwumuti burashobora kugira ingaruka.
3. Gukoresha HPMC
Bitewe n’amazi meza yo gukama, uburozi buke, hamwe nubwiza bushobora guhinduka, HPMC ikoreshwa cyane mubikorwa bitandukanye.
Uruganda rwa farumasi: Mu nganda zimiti, HPMC ikoreshwa cyane mugutegura-kurekura imiti irambye, ibinini, ibinini, hamwe nabatwara ibiyobyabwenge. Irashobora gufasha ibiyobyabwenge gushonga mumazi no kugabanya igipimo cyo gusohora ibiyobyabwenge.
Inganda zibiribwa: HPMC, nk'inyongeramusaruro y'ibiribwa, ikoreshwa muburyo bwa emulisile, kubyimba, no gutanga amazi. Mubicuruzwa bitetse, birashobora kunoza ihindagurika no gukomera kwifu. HPMC ikoreshwa kandi muri ice cream, ibinyobwa nibiryo birimo amavuta make.
Inganda zubwubatsi: Mu nganda zubwubatsi, HPMC ikunze gukoreshwa nkibyimbye mu kubaka minisiteri, ishobora kunoza imikorere yubwubatsi, gufata amazi no guhuza imbaraga za minisiteri.
Amavuta yo kwisiga: Mu kwisiga, AnxinCel®HPMC ikoreshwa cyane cyane mubyimbye, igahagarika ibintu na stabilisateur, kandi ikoreshwa cyane mubicuruzwa nka cream yo mumaso, shampo, na geles yo koga.
HPMCni amazi-ashonga kandi akomoka cyane kuri selile ikomoka kuri selile ishobora gukora igisubizo kibonerana mumazi. Ntabwo ari umusemburo, ahubwo ni molekile ndende ishobora gushonga mumazi. Ububasha bwabwo bugaragarira cyane cyane muburyo bwiza bwo gukama mumazi, ariko ntibishobora gushonga mumashanyarazi menshi. Ibi biranga HPMC bituma ikoreshwa cyane mu nganda nyinshi, harimo imiti, ibiryo, ubwubatsi, no kwisiga.
