Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, waxay fududaysaa propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, soo gaabinta), waa inay ka tirsan tahay noocyo kala duwan oo isku dhafan oo aan-ionic cellulose eter ahayn.Waa semi-synthetic, aan firfircoonayn, polymer viscoelastic ah oo caadi ahaan loo isticmaalo cilmiga indhaha sida saliidayn ahaan, ama saafiye ahaan ama kaxeeya dawooyinka afka, sida caadiga ah laga helo badeecooyin kala duwan.Hydroxypropyl cellulose waxa loo isticmaali karaa cunto lagu daro, emulsifier, dhumuc weyn, wakiilka ganaaxa iyo beddelka jelatin xoolaha.

Hydroxypropyl Methylcellulose HPMC/HEC/MHPC
Hydroxypropyl methylcellulose, oo sidoo kale loo yaqaan hypromellose, waa mid ka mid ah ethers-ka isku dhafan ee aan-ionic cellulose. Waa semi-synthetic, aan firfircoonayn, polymer viscoelastic, oo inta badan loo isticmaalo saliidaha indhaha, ama ka-qaadista ama ka-qaadista daawada afka.
Waxay ku milmi kartaa biyaha iyo qaar ka mid ah dareerayaasha, sida ethanol/biyaha, propanol/biyaha oo ah saamiga ku habboon.Xalka aqueous wuxuu leeyahay hawlo dusha sare ah.Daah-furnaan sare iyo waxqabad xasilloon.Tilmaamaha kala duwan ee alaabadu waxay leeyihiin heerkul jel oo kala duwan iyo isbeddelka milanka leh ee viscosity.Maqnaanshaha hoose, ayaa sii weynaan kara milanka.Tilmaamaha kala duwan ee HPMC waxay leeyihiin bandhigyo kala duwan.Kala dirida HPMC ee biyaha ma saamayso pH.
