IHydroxypropyl methylcellulose (HPMC) iyimpahla ye-polymer esetshenziswa kakhulu kuzimonyo nemikhiqizo yokunakekela umuntu. Inezinto ezihlukahlukene eziyingqayizivele ngokomzimba namakhemikhali, okwenza kube esinye sezithako ezibaluleke kakhulu kulo mkhakha.
1. I-thickener ne-stabilizer
Okunye okuvamile ukusetshenziswa kwe-HPMC ezimonyoni iwukuqina kanye nokuqiniswa. Ngenxa yokuncibilika kwayo emanzini kanye nekhono layo lokwenza ama-gel ngaphansi kwezimo ezithile, i-HPMC ingakhuphula ngempumelelo i-viscosity nokuvumelana komkhiqizo, okwenza umkhiqizo ube lula ukuwusebenzisa esikhumbeni futhi ube nokuthinta kahle. Isibonelo, kuma-lotions, okhilimu nama-gel, i-HPMC inganikeza umkhiqizo ukuthungwa okuzinzile, ivimbele ukuhlukaniswa nokuhlukaniswa, futhi ngaleyo ndlela yandise impilo yeshalofu yomkhiqizo.
2. Ifilimu yangaphambili
I-HPMC futhi iyifilimu enhle kakhulu yangaphambili. Emikhiqizweni yezimonyo neyokunakekelwa komuntu siqu, ingenza ifilimu esobala, ethambile ebusweni besikhumba, enokuphefumula okuhle ngenkathi igcina umswakama wesikhumba futhi ivimbela ukulahleka komswakama. Lesi sakhiwo senza i-HPMC isetshenziswe kabanzi emikhiqizweni ethambisayo, imaski yobuso nezivikela-langa. Ngaphezu kwalokho, ifilimu eyakhiwe yi-HPMC ingaphinde ithuthukise ukuqina komkhiqizo, ivumele izimonyo ukuthi zihlale esikhumbeni isikhathi eside.
3. I-Emulsion stabilizer
Kumafomula amaningi ezimonyo, i-HPMC idlala indima ebalulekile njenge-emulsion stabilizer. Ingenza uhlelo lwe-emulsion oluzinzile phakathi kwesigaba samafutha kanye nesigaba samanzi ukuvimbela ukuhlukaniswa kwesigaba. Lokhu kubaluleke kakhulu emikhiqizweni efana nama-lotions nama-creams. Ukuba khona kwe-HPMC kuqinisekisa ukufana nokuzinza kwale mikhiqizo futhi kuthuthukisa ulwazi lomsebenzisi.
4. Okokuthambisa
I-HPMC inezinto ezinhle zokuthambisa, okuyenza isetshenziswe kabanzi emikhiqizweni yokunakekelwa kwesikhumba. Ingakwazi ukumunca futhi ivale umswakama ukusiza ukugcina ukugeleza kwesikhumba. Lesi sici sifaneleka ngokukhethekile isikhumba esomile kanye nemikhiqizo elwa nokuguga, engakhulula ngokuphumelelayo isikhumba esomile futhi ithuthukise ukunwebeka kwesikhumba nokukhanya.
5. I-Solubilizer
Kweminye imikhiqizo yezimonyo neyokunakekelwa komuntu siqu, i-HPMC ingasetshenziswa futhi njengesixazululi ukusiza ukuncibilikisa izithako ezithile ezisebenzayo ezingancibiliki ukuze zihlakazwe kangcono kufomula. Lokhu kunenzuzo kakhulu emikhiqizweni equkethe izitshalo zezitshalo noma amafutha abalulekile, angathuthukisa ukuzinza kanye ne-bioavailability yalezi zithako ezisebenzayo futhi kuthuthukise ukusebenza kahle komkhiqizo.
6. I-ejenti yokumisa
I-HPMC ingasebenza njenge-ejenti emisiwe ukusiza ngokulinganayo ukuhlakaza kanye nokusimamisa izinhlayiya eziqinile ezimiswe oketshezini. Emikhiqizweni yezimonyo efana nesisekelo nesifutho se-sunscreen, ikhono lokumisa okwesikhashana le-HPMC lingaqinisekisa ukuthi ama-pigments noma ama-sunscreens emkhiqizweni asakazwa ngokulinganayo, kugwenywe imvula nokuhlukana, ngaleyo ndlela kuqinisekiswe ukuvumelana nokusebenza komkhiqizo.
7. I-Lubricant ne-touch modifier
I-HPMC futhi inokuthambisa okuhle kanye nemiphumela yokushintsha ukuthinta kuzimonyo. Ingenza umkhiqizo uzizwe usilika, wenze umkhiqizo ube bushelelezi futhi ukhululeke kakhudlwana uma usetshenziswa. Lesi sici sibaluleke kakhulu emikhiqizweni yezimonyo eyisisekelo (efana ne-foundation ne-BB cream) kanye nemikhiqizo yokunakekelwa kwezinwele, engathuthukisa kakhulu umuzwa womkhiqizo.
8. I-cellulose encibilikayo
I-HPMC empeleni iphuma ku-cellulose ngakho-ke iyisithako esibolayo. Lokhu kuyenza isetshenziswe kakhulu kuzimonyo ezihambisana nemvelo kanye nemikhiqizo yokunakekelwa komuntu siqu, ukuhlangabezana nesidingo sabathengi sezithako ezisimeme nezemvelo. Ukunyibilika kwe-HPMC kuyenza idume kumamaski ancibilika emanzini, izihlanzi nemikhiqizo ehlanzwa, ephephile futhi ehambisana nemvelo.
9. Ukucasuka okuphansi
I-HPMC inokucasuka okuphansi kanye ne-biocompatibility enhle, okuyenza ifanelekele ukusetshenziswa emikhiqizweni yesikhumba esibucayi kanye naseduze kwamehlo. Ubumnene bayo buyenza isetshenziswe kabanzi kumakhilimu wamehlo, okhilimu bobuso kanye nemikhiqizo yokunakekela izingane, okunganciphisa ngempumelelo ingozi yokucasuka kwesikhumba noma ukungezwani komzimba okubangelwa imikhiqizo.
10. Isithuthukisi
Okokugcina, i-HPMC ingasetshenziswa futhi njenge-synergist ekwenziweni kwezimonyo ukuthuthukisa ukusebenza kahle okuphelele komkhiqizo ngokuthuthukisa ukunyibilika, ukuhlakazeka noma ukuqina kwezinye izithako. Isibonelo, emikhiqizweni elwa nokushwabana, i-HPMC ingasiza izithako ezisebenzayo zingene kangcono esikhumbeni, ngaleyo ndlela ithuthukise imiphumela yokulwa nokuguga.
IHydroxypropyl methylcellulose (HPMC) idlala izindima ezihlukene ezibalulekile kuzimonyo nemikhiqizo yokunakekelwa komuntu siqu, kusukela ekushubiseni nasekuswameni kuya ekubunjweni kwefilimu nasekuqiniseni i-emulsion. Ukuhlukahluka kwe-HPMC kuyenza ibe isithako esingabuyiseleki futhi esibalulekile ekwakhiweni kwezimonyo. Njengoba abathengi beqhubeka nokwandisa izidingo zabo zokuthungwa komkhiqizo, ukuzinza nokuvikelwa kwemvelo, i-HPMC izoqhubeka idlala indima ebalulekile ezinkambini zesikhathi esizayo zezimonyo kanye nokunakekelwa komuntu siqu.
