Ni bangahe uzi kuri Hydroxypropyl methyl selulose?

Hydroxypropyl methylcellulose (HPMC) ni selile ya selile ikomoka kuri selile naturel. Ni sintetike, ibora amazi, idafite ionic polymer ikunze gukoreshwa mubikorwa bitandukanye nkubwubatsi, imiti, ibiryo, amavuta yo kwisiga, hamwe n imyenda.

HPMC ikorwa no guhindura imiti ya selile hamwe na propylene oxyde na methyl chloride kugirango yinjize hydroxypropyl na methyl mumatsinda ya selile. Urwego rwo gusimbuza (DS) rwa HPMC bivuga umubare wa hydroxypropyl na methyl mumatsinda ya anhydroglucose (AGU) ya selile.

HPMC ifite imitungo myinshi ituma igira akamaro mubikorwa bitandukanye. Irashobora gushonga mumazi, ikora igisubizo gisobanutse, kandi ifite ubushyuhe bwiza. Irahagaze kandi mubihe bisanzwe byubushyuhe na pH kandi ntishobora kubora byoroshye. HPMC ni hygroscopique, bivuze ko ishobora gukurura no kugumana ubushuhe. Ntabwo ari uburozi, butarakara, kandi butari allergene, butuma burinda gukoreshwa mubisabwa byinshi.

Mu nganda zubaka, HPMC ikoreshwa nkibikoresho byongera umubyimba, uhuza, hamwe n’amazi agumana amazi mu bicuruzwa bishingiye kuri sima, ibifata amatafari, plaster, nibindi bikoresho byubaka. Mu nganda zimiti, HPMC ikoreshwa nka binder, disintegrant, na firime-yahoze muri tablet na capsule. Mu nganda zibiribwa, HPMC ikoreshwa nkibibyimbye, emulisiferi, na stabilisateur mubicuruzwa bitandukanye. Mu kwisiga, HPMC ikoreshwa nkibyimbye, firime-yahoze, na emulisiferi mumavuta, amavuta yo kwisiga, nibindi bisobanuro.

Muri rusange, HPMC ni polymer itandukanye kandi ifite akamaro ifite porogaramu zitandukanye mubikorwa bitandukanye kubera imiterere yihariye.
