HPMC, kapa Hydroxypropyl Methylcellulose, ha se surfactant ka kutloisiso e thata ea lentsoe. Li-surfactants ke limolek'hule tse nang le lipheletso tsa hydrophilic (tse ratang metsi) le hydrophobic (tse thibelang metsi), 'me li sebelisetsoa ho fokotsa tsitsipano ea holim'a metsi a mabeli a sa khoneheng kapa pakeng tsa mokelikeli le se tiileng. Li-surfactants li sebelisoa hangata liindastering tse fapaneng, ho kenyeletsoa lihlahisoa tsa ho hloekisa, lihlahisoa tsa tlhokomelo ea motho, le meriana, har'a tse ling.

Ka lehlakoreng le leng, HPMC ke polymer e thehiloeng ho cellulose e sebelisoang lits'ebetsong tse fapaneng, ho kenyelletsa le meriana, lijo le lihlahisoa tsa tlhokomelo ea motho, har'a tse ling. HPMC e hlahisoa ke cellulose e fetolang lik'hemik'hale, e leng polima ea tlhaho e fumanoang limela. Haholo-holo, HPMC e hlahisoa ka ho kenya lihlopha tse ling tsa hydroxyl sebakeng sa selulose ka lihlopha tsa methyl kapa hydroxypropyl. Polymer e hlahisoang e qhibiliha ka metsing 'me e ka sebelisoa e le sekontiri, se tlamang, sa emulsifier le stabilizer, har'a mesebetsi e meng.

Leha e se motho ea sebetsang ka holim'a metsi, HPMC e ka bonts'a thepa e kang ea surfactant lits'ebetsong tse ling. Ka mohlala, HPMC e ka sebelisoa ho tsitsisa li-emulsion, e leng metsoako ea metsi a mabeli a sa tsitsang, ka ho etsa lesela le sireletsang ho pota-pota marotholi a mokelikeli o mong ka har'a metsi a mang. Lera lena le ka thibela marotholi ho kopana le ho arohana le motsoako o mong. Ka tsela ena, HPMC e ka sebetsa joalo ka emulsifier, e leng mofuta oa surfactant.

Ho feta moo, HPMC e ka sebelisoa ho fokotsa tsitsipano ea metsi, e leng thepa ea li-surfactants. Ka mohlala, HPMC e ka sebelisoa e le ho roala holim'a libaka tse tiileng ho etsa hore li be le hydrophilic, tse ka eketsang thepa ea tsona ea ho kolobisa. Ts'ebetsong ena, HPMC e ka fokotsa tsitsipano ea metsi holim'a metsi a koahetsoeng, a ka ntlafatsang ho khomarela ha metsi kapa lintho tse tiileng holim'a metsi.

Ka kakaretso, le ha HPMC e se sebatli ka kutloisiso e thata ea lentsoe, e ka bonts'a thepa e ts'oanang le surfactant lits'ebetsong tse itseng. HPMC ke polymer e feto-fetohang e ka sebelisoang liindastering tse fapaneng, 'me thepa ea eona e ikhethang e e etsa motsoako oa bohlokoa mekhoeng e mengata.
