Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, wosalira zambiri propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, chidule), ndi m'gulu osiyanasiyana osakaniza non-ionic cellulose ether.Ndi semi-synthetic, inactive, viscoelastic polima yomwe imagwiritsidwa ntchito kwambiri mu ophthalmology ngati mafuta, kapena ngati othandizira kapena othandizira pakamwa, omwe amapezeka muzambiri zosiyanasiyana.Ma cellulose a Hydroxypropyl atha kugwiritsidwa ntchito ngati chowonjezera cha chakudya, emulsifier, thickener, kuyimitsidwa ndi choloweza mmalo mwa gelatin yanyama.

Hydroxypropyl Methylcellulose HPMC/HEC/MHPC
Hydroxypropyl methylcellulose, yomwe imadziwikanso kuti hypromellose, ndi imodzi mwa ma cellulose osakanizidwa a ether omwe si a ionic. Ndi semi-synthetic, inactive, viscoelastic polima, yomwe nthawi zambiri imagwiritsidwa ntchito ngati mafuta mu ophthalmology, kapena ngati wothandizira kapena wothandizira pakamwa mankhwala.
Imasungunuka m'madzi ndi zosungunulira zina, monga ethanol/madzi, propanol/madzi molingana.Njira yamadzimadzi imakhala ndi ntchito pamtunda.Kuwonekera kwapamwamba komanso magwiridwe antchito okhazikika.Zosiyanasiyana zazinthu zimakhala ndi kutentha kosiyanasiyana kwa gel osakaniza ndi kusintha kwa kusungunuka ndi mamasukidwe akayendedwe.M'munsi mamasukidwe akayendedwe, kwambiri solubility.Mafotokozedwe osiyanasiyana a HPMC ali ndi machitidwe osiyanasiyana.Kutha kwa HPMC m'madzi sikukhudzidwa ndi pH.
