Hydroxypropyl MethylCellulose E464

Hydroxypropyl Methylcellulose (HPMC) ni igice cya sintetike ya polymer ikomoka kuri selile. Bikunze gukoreshwa mu nganda zibiribwa nkinyongeramusaruro hamwe na E nimero E464.

HPMC ikorwa mukuvura selile hamwe nuruvange rwa alkali na etherification, bikavamo gusimbuza amwe mumatsinda ya hydroxyl kuri molekile ya selile hamwe na hydroxypropyl na methyl. Urwego rwo gusimbuza rugena imiterere ya HPMC yavuyemo, nkibishobora gukemuka hamwe na gelation.

Mu biryo, HPMC ikoreshwa nkibyimbye, emulifier, na stabilisateur, mubindi bikorwa. Irashobora gukoreshwa mugutezimbere ibicuruzwa byibiribwa nka sosi, imyambarire, nibicuruzwa bitetse. HPMC ikoreshwa kandi nk'igifuniko cya tableti na capsules mu nganda zimiti, ndetse no mubikorwa byo kwita kubantu no kwisiga.

Muri rusange HPMC ifatwa nk’umutekano muke kandi yemerewe gukoreshwa mu biribwa n’inzego nyinshi zishinzwe kugenzura isi, harimo n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) n’ikigo cy’uburayi gishinzwe umutekano w’ibiribwa (EFSA). Ariko, kimwe ninyongeramusaruro zose, ni ngombwa gukoresha HPMC ukurikije urwego n'amabwiriza asabwa kugirango umutekano wacyo ube.
