Hydroxypropyl Methylcellulose (HPMC)ni ifumbire mvaruganda ya polymer ikomoka kuri selile naturel kandi ikoreshwa cyane mubicuruzwa bitandukanye byita kuruhu, kwisiga nibicuruzwa bya farumasi. Nka selile yahinduwe, ntabwo ikoreshwa cyane munganda gusa, ahubwo inagira uruhare runini mubicuruzwa byuruhu.
1. Inkoko hamwe na stabilisateur
Hydroxypropyl methylcellulose ni umubyimba mwiza ushobora kongera cyane ubwiza bwibicuruzwa byita ku ruhu kandi bigafasha ibicuruzwa gukora neza. Ubusanzwe yongerwamo amavuta yo kwisiga, amavuta, isuku yo mumaso nibindi bicuruzwa kugirango bitange ubukonje buringaniye, ntabwo byoroshye kubishyira mubikorwa gusa, ahubwo binongera imikoreshereze nuburyo bwiza bwibicuruzwa.
Byongeye kandi, ingaruka zibyibushye za HPMC muri formula zifasha guhagarika imiterere ya emulsiyo, kurinda ibice cyangwa gutandukanya amavuta-mazi, no kongera igihe cyibicuruzwa. Mu kongera ububobere muri formula, bituma imikoranire hagati yicyiciro cyamazi nicyiciro cyamavuta ihagarara neza, bityo bigatuma uburinganire nuburinganire bwibicuruzwa nka amavuta yo kwisiga hamwe na cream.
2. Ingaruka nziza
Hydroxypropyl methylcellulose ifite hydrated nziza, kandi molekile zayo zirimo amatsinda ya hydrophilique ashobora gukora hydrogène ya hydrogène hamwe na molekile y'amazi kugirango ifashe kugumana ubushuhe. HPMC ntabwo igira uruhare runini mubicuruzwa byita ku ruhu, ahubwo ikurura kandi igafunga ubuhehere, butanga ingaruka zigihe kirekire. Ibi bifasha cyane cyane kuruhu rwumye cyangwa ibihe byumye byuruhu, bikomeza uruhu.
Mu mavuta amwe n'amavuta yo kwisiga arimo hydroxypropyl methylcellulose, imbaraga zazo zituma zirushaho kwiyongera, bigatuma uruhu rwumva rworoshye, rworoshye kandi rutumye kandi rukomeye.
3. Kunoza uruhu kumva no gukoraho
Kubera ko imiterere ya molekuline ya HPMC ifite urwego runaka rwo guhinduka, irashobora kunoza cyane imyumvire yibicuruzwa byita kuruhu, bigatuma byoroha kandi byoroshye. Mugihe cyo kuyikoresha, hydroxypropyl methylcellulose irashobora guha ibicuruzwa ibicuruzwa byoroshye, byoroshye, kugirango uruhu rutazumva amavuta cyangwa gukomera nyuma yo kubisaba, ariko bizahita byinjira kugirango bigumane ingaruka nziza kandi nziza.
Iri terambere ryimiterere ni ikintu gihangayikishije cyane abaguzi, cyane cyane kubakoresha bafite uruhu rworoshye cyangwa rufite amavuta, aho kumva mugihe cyo gukoresha ari ngombwa cyane.
4. Kugenzura ibintu bitembera no gukwirakwizwa kwa formula
Ingaruka yo kubyimba yaHPMCntabwo ituma ibicuruzwa byiyongera gusa, ahubwo inagenzura ibicuruzwa bitembera neza, bigatuma ikoreshwa neza. Cyane cyane kubintu bimwe na bimwe byo kwisiga hamwe na gel, gukoresha hydroxypropyl methylcellulose birashobora kunoza uburinganire bwokoresha, bigatuma ibicuruzwa bikwirakwira neza kuruhu nta gutonyanga cyangwa imyanda.
Mu mavuta amwe n'amwe cyangwa ibicuruzwa byitaweho, kongeramo hydroxypropyl methylcellulose birashobora kunoza neza uburyo bwogukoresha neza, bigatuma ibicuruzwa byakoreshwa neza mubice byuruhu byoroshye bitarinze gutera ikibazo.
5. Nkumukozi uhagarika
Hydroxypropyl methylcellulose ikunze gukoreshwa nkigikoresho cyo guhagarika ibicuruzwa bimwe na bimwe byita ku ruhu, cyane cyane birimo ibintu bikora cyangwa ibintu bya granulaire. Irashobora gukumira neza imvura cyangwa gutandukanya ibintu bikomeye (nkibice byamabuye y'agaciro, ibimera bivamo ibihingwa, nibindi), kwemeza ko ibintu byose biri muri formula bigabanijwe neza, kandi bikirinda kugira ingaruka kumikorere no kugaragara kubicuruzwa bitewe nubushyuhe bwibintu cyangwa urwego.
Kurugero, mumasike amwe yo mumaso arimo ibice bya scrub cyangwa ibimera bivamo ibihingwa, HPMC irashobora gufasha gukomeza gukwirakwiza ibice, bityo bikazamura imikorere yibicuruzwa.
6. Kwitonda no kutarakara
Nkibintu byakuwe muri selile karemano, hydroxypropyl methylcellulose ubwayo ifite biocompatibilité na hypoallergenicity, bityo ikwiranye nubwoko bwose bwuruhu, cyane cyane uruhu rworoshye. Ubwitonzi bwayo butuma umutekano ukoreshwa mubicuruzwa bitandukanye byita ku ruhu udateye kurakara cyangwa kubangamira uruhu.
Ibiranga bituma HPMC ikoreshwa mubintu byinshi mugihe utezimbere ibicuruzwa byuruhu rworoshye, kwita kuruhu rwabana, nibicuruzwa bitarimo inyongeramusaruro.
7. Kunoza imikorere ya antioxydeant no kurwanya umwanda
Ubushakashatsi bumwe bwerekanye ko imiterere ya molekile ya hydroxypropyl methylcellulose, ikomoka kuri selile isanzwe, ishobora gutanga antioxydants no kurwanya umwanda ku rugero runaka. Mu bicuruzwa byita ku ruhu, birashobora gukoreshwa bifatanije nibindi bintu birwanya antioxydeant (nka vitamine C, vitamine E, nibindi) kugirango bifashe gukuraho radicals yubusa no gutinda gusaza kwuruhu. Byongeye kandi, imiterere ya hydrophilique ya HPMC irashobora gufasha kurinda uruhu umwanda uhumanya ikirere.
Hydroxypropyl methylcelluloseigira uruhare runini mubicuruzwa byita kuruhu. Ntishobora gusa kuba umubyimba no guhagarika ibintu kugirango yongere ubwiza no kumva ibicuruzwa, ariko kandi ifite imirimo yingenzi nko gutobora, kunoza uruhu, no kugenzura amazi. Nibintu byoroheje kandi byiza, birashobora kunoza imikorere yibicuruzwa byuruhu hamwe nuburambe bwabaguzi. Ikoreshwa cyane mubicuruzwa bitandukanye byita kuruhu nka cream yo mumaso, amavuta yo kwisiga, koza mumaso, hamwe na masike yo mumaso. Mugihe ibikenerwa mubintu bisanzwe nibicuruzwa byita kuruhu bikomeje kwiyongera, hydroxypropyl methylcellulose izakomeza kugira uruhare runini mugutezimbere ibicuruzwa byita kuruhu.
