Malunga neqondo lokushisa le-gedroxypropyl methyl seluploseI-HPMC, Abasebenzisi abaninzi banqabile ukuba banikele ingqalelo kwiqondo lokushisa le-gedroxypropy ye-methyl seluplose. Ngoku i-hydroxypropyl methyl seluplose ihlulelwe ngokubanzi ngokobume bayo, kodwa ngenxa yendawo ethile kunye namashishini awodwa, akwanele ukubonakalisa i-viscofity yemveliso. Oku kulandelayo kwazisa ngobushushu be-gene ye-hydroxypropyl methylcelcelcelcelceluplose.
Umxholo we-2000 inxulumene ngqo nenqanaba le-sylysis yesifo sesellulose, kwaye umxholo wama-Apciaxy unokuhlengahlengiswa ngokulawula ifomula, ubushushu bokuphendula kunye nexesha lokuphendula. Kwangelo xesha, inqanaba lebhokisi yebhokisi ye-bodyboysition ichaphazela inqanaba lokufakwa endaweni ye-hydroxyyl okanye i-hydroxypropyl. Ke ngoko, ukugcinwa kwamanzi se-seluplose Talsulose TOS ngeqondo lokushisa eliphezulu le-gene ngokubanzi libi kakhulu. Le nkqubo yemveliso kufuneka iphononongwe, ngoko ayisiyomveliso yeqela le-APENS liphantsi, iindleko zemveliso ze-Taluplose i-Ether iphantsi, ngokuchaseneyo, ixabiso layo liya kuba ngaphezulu.
Iqondo lobushushu le-gel limiselwa liqela le-Macwitchy, kwaye ukugcinwa kwamanzi kugqitywa yiqela le-hydroxypropoxyproxy. Kukho amaqela amathathu kuphela kwi-seluplose. Fumana iqondo lobushushu elifanelekileyo lokusebenzisa, ukugcinwa kwamanzi ngokufanelekileyo, kwaye emva koko ubone imodeli yale seluplose.
Iqondo lokushisa le-gel yindawo ebalulekileyo yokusetyenziswa kweI-Selersese Ether. Xa ubushushu obungaphantsi kwamaqondo obushushu bugqitha ubushushu be-gel, i-Ethesese I-Ethe iyahlulahlula amanzi kwaye iphulukane nokugcinwa kwamanzi. Iqondo lokushisa le-gel sellulose i-ether kwimarike linokuhlangabezana neemfuno zendawo esetyenziswayo ngudaka (ngaphandle kwendawo ezikhethekileyo). Abavelisi kufuneka bathathele ingqalelo le nto.
