I-HPMC, noma i-Hydroxypropyl Methylcellulose, ayiyona i-surfactant ngomqondo oqinile waleli gama. Ama-surfactants ama-molecule anazo zombili iziphetho ze-hydrophilic (ezithanda amanzi) kanye ne-hydrophobic (ezixosha amanzi), futhi asetshenziselwa ukunciphisa ukungezwani okungaphezulu phakathi koketshezi olubili olungaguquki noma phakathi koketshezi nokuqinile. Ama-surfactants avame ukusetshenziswa ezinhlobonhlobo zezimboni, okubandakanya imikhiqizo yokuhlanza, imikhiqizo yokunakekelwa komuntu siqu, kanye nemithi, phakathi kokunye.

Ngakolunye uhlangothi, i-HPMC iyi-polymer esekwe ku-cellulose esetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi imithi, ukudla, nemikhiqizo yokunakekela komuntu siqu, phakathi kokunye. I-HPMC ikhiqizwa i-cellulose eshintsha amakhemikhali, okuyi-polymer yemvelo etholakala ezitshalweni. Ngokukhethekile, i-HPMC ikhiqizwa ngokufaka amanye amaqembu e-hydroxyl ku-cellulose ngamaqembu e-methyl noma e-hydroxypropyl. I-polymer ewumphumela iyancibilika emanzini futhi ingasetshenziswa njenge-thickener, binder, emulsifier, kanye ne-stabilizer, phakathi kweminye imisebenzi.

Naphezu kokungeyona i-surfactant, i-HPMC ingabonisa izici ezifana ne-surfactant kwezinye izinhlelo zokusebenza. Isibonelo, i-HPMC ingasetshenziselwa ukuzinzisa ama-emulsion, okuyingxube yoketshezi olubili olungaguquki, ngokwenza ungqimba oluvikelayo oluzungeze amaconsi oketshezi olulodwa kolunye uketshezi. Lolu ungqimba lungavimbela amaconsi ukuthi angahlangani futhi ahlukane nayo yonke ingxube. Ngale ndlela, i-HPMC ingasebenza njenge-emulsifier, okuwuhlobo lwe-surfactant.

Ngaphezu kwalokho, i-HPMC ingasetshenziswa ukunciphisa ukushuba kwamanzi emanzini, okuyindawo yama-surfactants. Isibonelo, i-HPMC ingasetshenziswa njengendlela yokwemboza ezindaweni eziqinile ukuze kuzenze zibe ne-hydrophilic, okungakhuphula izakhiwo zazo zokumanzisa. Kulolu hlelo lokusebenza, i-HPMC inganciphisa ukungezwani okungaphezulu kwamanzi endaweni eboshwe, engathuthukisa ukunamathela koketshezi noma okuqinile phezulu.

Sekukonke, ngenkathi i-HPMC ingeyona i-surfactant ngomqondo oqinile waleli gama, ingabonisa izici ezifana ne-surfactant kwezinye izinhlelo zokusebenza. I-HPMC iyi-polymer eguquguqukayo engasetshenziswa ezinhlobonhlobo zezimboni, futhi izakhiwo zayo ezihlukile ziyenza ibe isithako esibalulekile ekwenziweni okuningi.
