Yini izakhiwo ze-hydroxypropyll methylcellulose?

I-Hydroxypropyl Methylcellulose (HPMC) iyinhlangano evamile yokususelwa esokisini, esetshenziswa kabanzi kwezokwelapha, ukudla, izinto zokwakha, amakhemikhali nsuku kanye nezinye izinkambu. Inezakhiwo ezizinzile zamakhemikhali kanye nokusebenza okuhle kakhulu. Izici zokusebenza eziphambili ze-HPMC zizoxoxwa ngokuningiliziwe ngezansi.
