Hydroxypropyl methylcellulose
HydroxypropylMethylcellulose (HPMC) kapena hypromellosendi chochokeras mankhwala a methyl cellulose ether. Zili chonchoulusi woyera kapena woyera kapena granularcellulose etherufa. Panopa ndi cellulose ether ndi ntchito yabwino kwambiri padziko lapansi, kuphatikiza kukhuthala, kuyimitsa, kubalalitsa, emulsifying ndi kukhazikika. Hydroxypropyl methyl cellulose (HPMC) si poizoni, yosavuta kugwiritsa ntchito, ndipo mosavuta kusungunuka m'madzi. Ndi polyanion mu njira yamadzimadzi ndipo imakhala ndi mawonekedwe apadera. Ntchito yeniyeni ndi ngati apa:
