1. Hydroxypropyl methyl cellulosesoluble na mmiri oyi, mmiri ọkụ gbazere ga-ezute ihe isi ike. Ma gelation okpomọkụ ya na mmiri ọkụ dị nnọọ elu karịa nke methyl cellulose. Solubility nke methyl cellulose na mmiri oyi na-akawanye mma nke ukwuu.
2. Viscosity nke hydroxypropyl methyl cellulose na-ejikọta ya na arọ molekụla ya, na ibu molekul buru ibu bụ viscosity dị elu. Okpomọkụ ga-emetụtakwa viscosity ya, okpomọkụ na-abawanye, viscosity na-ebelata. Otú ọ dị, viscosity nke elu okpomọkụ dị ala karịa nke methyl cellulose. Ngwọta ahụ kwụsiri ike mgbe echekwara ya na ụlọ okpomọkụ.
3. Hydroxypropyl methyl cellulose kwụsiri ike na acid na alkali, na mmiri mmiri ngwọta ya dị nnọọ ike na nso nke pH = 2 ~ 12. Caustic soda na mmiri lime enweghị mmetụta dị ukwuu na njirimara ya, mana alkali nwere ike mee ka ọnụego mgbasa ya dịkwuo elu ma melite viscosity nke ntụtụ. Hydroxypropyl methyl cellulose nwere nkwụsi ike na nnu n'ozuzu, ma mgbe ntinye nke ngwọta nnu dị elu, viscosity nke hydroxypropyl methyl cellulose ngwọta na-emekarị ka ọ dịkwuo elu.
4. Njide mmiri nke hydroxypropyl methyl cellulose na-adabere na ya na-agbakwụnye ego, viscosity, wdg. Ọnụego njide mmiri n'okpuru otu ihe mgbakwunye ahụ dị elu karịa nke methyl cellulose.
5. Adhesiveness nke hydroxypropyl methyl cellulose na ngwa agha owuwu dị elu karịa nke methyl cellulose.
6. Hydroxypropyl methyl cellulosenwere nguzogide enzyme dị mma karịa methyl cellulose, na ohere nke mmebi enzymatic na ngwọta dị ala karịa methyl cellulose.
