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

Hydroxypropyl Methylcellulose (MHPC)
Hydroxypropyl methylcellulose (MHPC) ndi opanda fungo, osakoma, opanda poizoni a cellulose ethers omwe akhala ndi magulu a hyrdroxyl pa unyolo wa cellulose m'malo mwa methoxy kapena hydroxypropyl gulu losungunuka bwino m'madzi. HPMC F60S ndi mkulu-kukhuthala kalasi amene ntchito monga thickener, binder, ndi filimu kale mu agrochemicals, zokutira, ziwiya zadothi, zomatira, inki, ndi ntchito zina zosiyanasiyana.

Ma cellulose a Hydroxyethyl (HEC)
Hydroxyethyl Cellulose(HEC) ndi polymer yopanda ion, yosungunuka m'madzi yochokera ku cellulose kudzera muzinthu zingapo zamankhwala komanso zathupi. viscous gel solution.Pamene pH mu njira 2 mpaka 12, yankho limakhala lokhazikika.Popeza gulu la HEC ndi lopanda madzi m'madzi, silingagwirizane ndi anions ena kapena cations komanso osakhudzidwa ndi mchere.
Koma molekyulu ya HEC imatha kupanga esterification, etherification, kotero ndizotheka kuipangitsa kuti isasungunuke m'madzi kapena kuwongolera katundu wake.HEC ilinso ndi luso lopanga filimu komanso ntchito zapamtunda.
