Hydroxypropyl methylcellulose ikozwe niki?

Hydroxypropyl methylcellulose (HPMC) ni sintetike, polymer-soluble polymer ikomoka kuri selile. Ni ifu yera, idafite impumuro nziza, idafite uburyohe ikoreshwa cyane nkibikoresho byibyimbye, emulisiferi, firime yahoze, na stabilisateur mu nganda nyinshi, harimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi.

HPMC ikorwa mugukora selile hamwe na okiside ya propylene na methyl chloride. Cellulose ni polysaccharide nicyo kintu cyingenzi kigize urukuta rw'ibimera kandi ni ibinyabuzima byinshi ku isi. Okiside ya Propylene ni ifumbire mvaruganda hamwe na formula ya chimique CH3CHCH2O. Methyl chloride ni gaze itagira ibara, yaka kandi ifite impumuro nziza.

Imyitwarire ya selile hamwe na oxyde ya propylene na methyl chloride bituma habaho amatsinda ya hydroxypropyl, ifatanye na molekile ya selile. Iyi nzira izwi nka hydroxypropylation. Amatsinda ya hydroxypropyl yongerera imbaraga za selile mu mazi, byoroshye gukoresha muburyo butandukanye.

HPMC ikoreshwa cyane mubikorwa bya farumasi nkibihuza, bidahwitse, kandi bihagarika umukozi muri tableti na capsules. Irakoreshwa kandi nkibyimbye na emulisiferi mumavuta yo kwisiga, hamwe na firime yahoze mumaso. Mu nganda zibiribwa, ikoreshwa nkibibyimbye, stabilisateur, na emulisiferi mu isosi, imyambarire, nibindi bicuruzwa. Mu nganda zubaka, zikoreshwa nk'ibikoresho muri sima na minisiteri, kandi nk'igifuniko kitarinda amazi kurukuta no hasi.

HPMC ni ibikoresho byizewe kandi bidafite uburozi byemejwe n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) kugira ngo gikoreshwe mu biribwa, imiti, no kwisiga. Yemejwe kandi n’ubumwe bw’ibihugu by’Uburayi (EU) kugira ngo ikoreshwe mu biribwa n’imiti.
