Hydroxypropyl methylcellulose (HPMC)ndi non-ionic cellulose ether chimagwiritsidwa ntchito mu chakudya, mankhwala, zomangamanga ndi zina. Amapangidwa kuchokera ku cellulose yachilengedwe kudzera mukupanga mankhwala monga alkalization ndi etherification, ndipo ali ndi izi:
4. Chilengedwe ndi biocompatibility
Kuteteza chilengedwe: HPMC ndi zinthu zomwe zimatha kuwonongeka ndi chilengedwe komanso zachilengedwe.
Chitetezo chachilengedwe: Monga chowonjezera chazakudya ndi mankhwala, chimakhala ndi kuyanjana kwabwino kwachilengedwe ndipo sichikhala chapoizoni komanso chosavulaza.
5. Kusintha kwa zinthu zakuthupi
The katundu HPMC (monga mamasukidwe akayendedwe ndi kutentha gel osakaniza) akhoza kusintha ndi kusintha mlingo wake m'malo (zili m'magulu methoxy ndi hydroxypropyl) kukwaniritsa zofunika zosiyanasiyana ntchito.
6. Kukana mankhwala
Mchere wosasunthika: Umakhala wokhazikika mumchere wambiri.
Kukana kwa Enzymatic: Poyerekeza ndi mapadi achilengedwe, HPMC ili ndi kukana kwamphamvu kwa enzymatic hydrolysis.
Hydroxypropyl methylcellulose yakhala ikugwiritsidwa ntchito m'mafakitale ambiri monga chakudya, mankhwala, ndi zomangamanga chifukwa cha zinthu zake zabwino kwambiri zakuthupi ndi zamankhwala, mawonekedwe amitundu yambiri, komanso kugwiritsa ntchito bwino. Kusungunuka kwake kwapadera kwamadzi, kukhuthala, kusunga madzi, komanso kupanga mafilimu kumapangitsa kuti ikhale chinthu chosasinthika komanso chofunikira.
