Hydroxypropyl methylcellulose siivulaza thupi la munthu, hydroxypropyl methyl cellulose ndiyotetezeka komanso yopanda poizoni, itha kugwiritsidwa ntchito ngati chakudya chowonjezera, ilibe kutentha, ndipo ilibe kukhumudwitsa pakhungu ndi mucous membrane. Nthawi zambiri amawona kuti ndi otetezeka 25mg / kg tsiku lililonse, zida zoteteza ziyenera kuvalidwa pakugwira ntchito.

Amayi oyamwitsa amamwa mkaka pamene akugwiritsa ntchito mankhwalawa, ndipo palibe zomwe zimanenedwa mwa makanda. Chifukwa chake, palibe zotsutsana zapadera za amayi apakati ndi oyamwa. Kugwiritsa ntchito hypromellose mwa ana sikuyambitsa zovuta zina poyerekeza ndi mibadwo ina, chifukwa chake ana amatha kugwiritsa ntchito mankhwalawa chimodzimodzi ndi akulu.

Zambiri

Makhalidwe a hydroxypropyl methylcellulose

1.Kufika pamlingo wapamwamba kwambiri wa ma cellulose ether, kukula kwake kwamamolekyulu, komanso kukweza kwa mawonekedwe amadzimadzi.

2. Kukwera kwamphamvu kwa cellulose ether, komwe kumakweza mawonekedwe ake amadzimadzi. Komabe, samalani posankha chakudya choyenera mukamagwiritsa ntchito kuti mupewe kudya kwambiri ndikukhudza matope ndi konkriti. khalidwe.

3. Monga zakumwa zambiri, mamasukidwe akayendedwe a cellulose ether adzachepa ndi kutentha, ndipo kukwera kwa kuchuluka kwa cellulose ether, kumapangitsa kwambiri kutentha.

4. Hydroxypropyl methylcellulose solution nthawi zambiri imakhala thupi la pseudoplastic, lomwe limatha kumeta ubweya. Kuchulukitsa kwakukulu pakuyesa, kumachepetsa kukweza. Chifukwa chake, kuphatikiza matope kumachepa chifukwa cha mphamvu yakunja, yomwe ikuthandizira kukonzekera matope, zomwe zimapangitsa kuti matopewo azigwira bwino ntchito komanso azigwirizana.

Njira yothetsera hydroxypropyl methylcellulose imawonetsera mawonekedwe amtundu wa Newtonia pomwe ndendeyo ndiyotsika kwambiri ndipo mamasukidwe akayendedwe amakhala ochepa. Pamene ndende ikuchulukitsidwa, njira yothetsera pang'onopang'ono imawonetsa mawonekedwe amadzimadzi a pseudoplastic, ndipo kukwera kwa ndende, kumawonekera kwambiri pseudoplasticity.
