Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, kurerutsa iyo propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, chidimbu), inofanira kunge iri yeakasiyana-siyana akasanganiswa asiri-ionic cellulose ether. Iyo semi-synthetic, isingashande, viscoelastic polymer inowanzoshandiswa muophthalmology semafuta ekuzora, kana semubatsiri kana excipient mumishonga yemuromo, inowanzo wanikwa mumhando dzakasiyana dzezvigadzirwa. Hydroxypropyl cellulose inogona kushandiswa sechikafu chekuwedzera, emulsifier, thickener, suspension agent uye mhuka inotsiva gelatin.

Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose(HEC) is a non-ionic,water-soluble polymer yakatorwa selulosi kuburikidza neakatevedzana emakemikari uye emuviri maitiro.HEC ichena kusvika kuchiedza yero, isinganhuhwi uye isinganakidze, inonyungudika mumvura inopisa kana inotonhora kuita viscous gel solution.Apo pH mumhinduro 2 kusvika ku12, mhinduro yacho yakanyatsogadzikana.Sezvo HEC boka riine nonionic imwe mumvura yemvura, haizogadziriswi nemamwe anion kana cations uye isinganzwisisi kune munyu.
Asi HEC molecule inokwanisa kugadzira esterification,etherification, saka zvinokwanisika kuita kuti isanyungudika mumvura kana kuvandudza zvinhu zvayo.HEC inewo unyanzvi hwakanaka hwekugadzira firimu uye basa repamusoro.
