HPMC, kapa Hydroxypropyl Methylcellulose, ha se surfactant ka kutloisiso e thata ea lentsoe lena.Li-surfactants ke limolek'hule tse nang le lipheletso tsa hydrophilic (tse ratang metsi) le tsa hydrophobic (tse thibelang metsi), 'me li sebelisetsoa ho fokotsa tsitsipano ea bokaholimo lipakeng tsa lino tse peli tse sa utloahaleng kapa lipakeng tsa mokelikeli le se tiileng.Li-surfactants li sebelisoa hangata liindastering tse fapaneng, ho kenyelletsa lihlahisoa tsa ho hloekisa, lihlahisoa tsa tlhokomelo ea motho ka mong, 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 lera 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.
