Methyl celluloulosee tšoeu kapa e tšoeu joaloka phofo ea fibrous kapa ea granular; E se nang le kotsi, e sa utloahaleng. Sehlahisoa sena ka metsing se ruruha tharollo e hlakileng kapa e bonolo ea colloidal; Ho inkela e phethahetseng, Chhloroform kapa Dithyl Ether. E hasana ka potlako le ho ruruha ka metsing a chesang ka 80-90 ℃, 'me e qhibiliha ka potlako kamora ho fola. The aqueous solution is quite stable at room temperature, and can gel at high temperature, and the gel can change with the solution with the temperature.
E na le bokhabane bo botle, bokollang, ho ts'oaroa, ho toba, ho boloka metsi le bokuli ba baesekopo. Filimi e na le bothata bo botle, ho feto-fetoha le maemo le pepeneneng. Hobane ha e khetholle, e ka lumellana le letsoai le leng le emmulier, empa ho bonolo ho tsoa, 'me tharollo e tsitsitse sehlahisoa sa carboxemeethyl ether Boholo ba selenoulose ether, ke phofo e tšoeu kapa e tšoeu e tšoeu kapa e tšoeu ea lisentitha tse tšoeu kapa tse nyane tsa 0.5-0.7 g Ho bonolo ho e hatisa ka metsing ka tharollo ea gelatinous e hlakileng, e sa rerolla ho Ethanol le li-solvents tse ling.
