I-HPMC (Hydroxypropyl Methyl Cellulose) iyinhlanganisela evamile ye-polymer esetshenziswa kakhulu emikhiqizweni yokunakekela umuntu. Ngenxa yezakhiwo zayo eziyingqayizivele zomzimba namakhemikhali, njengokuncibilika kwamanzi okuhle, ukulawulwa kwe-viscosity, ukwakheka kwefilimu esobala, umswakama nokuzinza, inokusetshenziswa okuningi okubalulekile emkhakheni wokunakekelwa komuntu siqu.
1. I-thickener ne-stabilizer
Njenge-thickener ne-stabilizer ephumelelayo, i-HPMC isetshenziswa kakhulu emikhiqizweni yokunakekelwa kwesikhumba, i-shampoo, ijeli yokugeza neminye imikhiqizo. Ingancibilika emanzini ukuze yenze isixazululo se-viscous, inikeze umkhiqizo i-viscosity efanelekile, iyenze ibe yinkimbinkimbi futhi izinzile ngesikhathi sokusetshenziswa.
Isibonelo, kumakhilimu noma ama-lotions, i-HPMC ingenza umkhiqizo ufane futhi ivimbele ukuhlukaniswa ngokulungisa i-viscosity yesisombululo. Lesi sici sifaneleka ngokukhethekile kumasistimu we-multiphase (njengamafutha emanzini noma ama-emulsions wamanzi ku-oyela), okusiza ukwakha isistimu e-emulsified ezinzile ukuvimbela ukuhlukaniswa kwezithako kanye nokuwohloka komkhiqizo. Ngaphezu kwalokho, ingakwazi ukuzinza ezinye izithako ezisebenzayo, njenge-vitamin C, i-retinol, njll, ukuze ukuphumelela kwalezi zithako kufomula kungagcinwa.
2. Abadali bamafilimu
I-HPMC inekhono elihle lokwenza ifilimu futhi ivamise ukusetshenziswa njengefilimu yangaphambili emikhiqizweni yokunakekelwa komuntu siqu. Isibonelo, emikhiqizweni yokunakekelwa kwezinwele, i-HPMC ingenza ifilimu yokuzivikela ebusweni bezinwele ukuze ivale umswakama futhi ivikele izinwele. Le filimu ayivimbeli kuphela ukulahlekelwa umswakama ezinweleni, kodwa futhi inikeza ukukhanya nokushelela kwezinwele, ngaleyo ndlela ithuthukise ukuthungwa kwezinwele ngemva kokusetshenziswa.
Ngaphezu kwalokho, i-HPMC isetshenziswa kabanzi kumaski obuso, izimonyo kanye nama-sunscreens. Ngemuva kokwakhiwa kwefilimu, i-HPMC ingenza ifilimu ephefumulayo, engakwazi ukukhiya ngokuphumelelayo izithako ezisebenzayo emkhiqizweni ukuze zivikeleke ekulahlekelweni noma ekushiseni, futhi ngesikhathi esifanayo ngeke zenze isikhumba sizizwe sisinda noma sinamathele, ngaleyo ndlela sithuthukise ulwazi lomsebenzisi.
3. Izinto zokuthambisa
I-HPMC futhi inezindawo ezinhle zokuthambisa emikhiqizweni yokunakekelwa komuntu siqu. Kungasiza isikhumba ukuba sigcine ibhalansi yomswakama ngokumunca umswakama ovela emoyeni, ngaleyo ndlela sithuthukise umphumela wokuthambisa wemikhiqizo yokunakekelwa kwesikhumba. Lesi sakhiwo senza i-HPMC ibe yingxenye ebalulekile yemikhiqizo eminingi ethambisayo, elungele ukusetshenziswa emikhiqizweni yokunakekela isikhumba esomile.
Kwezinye izifutho ezithambisayo noma amathoni, i-HPMC ayikwazi ukusiza ukukhiya umswakama kuphela, kodwa futhi inikeze umkhiqizo ukuthinta kasilika futhi ithuthukise ukunethezeka lapho isetshenziswa.
4. Okokugcoba
I-HPMC ingasetshenziswa futhi njengesigcobo ukuze inikeze ulwazi olubushelelezi emikhiqizweni yokunakekelwa komuntu siqu. Emikhiqizweni efana nokhilimu wokushefa namajeli, i-HPMC isiza ekunciphiseni ukungqubuzana, inciphise ukucasuka kwesikhumba, futhi inikeze umuzwa wokushefa obushelelezi. Ngaphezu kwalokho, kwezinye izinto zokunakekelwa kwesikhumba noma izinto eziyisisekelo, zinganikeza ukuthinta okubushelelezi nokuthambile futhi kuthuthukise ukunethezeka okuphelele komkhiqizo.
5. Isilawuli segwebu
I-HPMC ingasetshenziswa futhi njengesilawuli segwebu ukulawula ukukhiya komkhiqizo. Ezihlanzini zobuso namajeli okugeza, inani elifanele le-HPMC lingasiza umkhiqizo wenze igwebu elithambile neliqinile, lithuthukise umphumela wokuhlanza nolwazi lomsebenzisi. Ngesikhathi esifanayo, kusiza futhi ukuvimbela ukwakheka kwegwebu ngokweqile, ngaleyo ndlela kuthuthukise ukusebenza kahle kokuhlanza komkhiqizo nokunciphisa ukungcola kwamanzi ngesikhathi sokuhlanza.
6. Ukuphepha nobumnene
I-HPMC ithathwa njengento eluhlaza ephephile futhi engacasukeli kancane, okwenza isetshenziswe kabanzi emikhiqizweni yokunakekelwa kwesikhumba ebucayi kanye nemikhiqizo yokunakekela izingane. Uma kuqhathaniswa namanye amakhemikhali acasula kakhulu, i-HPMC iphansi kakhulu ekucasukeni esikhumbeni futhi ayijwayele ukungezwani nemizwa. Ngakho-ke, ivame ukusetshenziswa emikhiqizweni yokunakekelwa kwesikhumba yansuku zonke njengezihlanzi zobuso kanye nama-lotions ukusiza ukudala umuzwa omnene wokusetshenziswa.
Ngenxa yemvelo engeyona i-ionic ye-HPMC, iphinde ihambisane kakhulu nezinye izithako zamakhemikhali futhi ingasetshenziswa nezinhlobonhlobo zezithako ezisebenzayo ngaphandle kokukhiqiza ukusabela kwamakhemikhali okubi. Lokhu kubaluleke kakhulu kumafomula ayinkimbinkimbi ukuze kuqinisekiswe ukuzinza nokusebenzisana phakathi kwezithako ezahlukene.
7. Ukubambezeleka komphumela wokukhishwa kwemikhiqizo
Kweminye imikhiqizo yokunakekelwa okukhethekile, efana namakhilimu alwa nokuguga, izimonyo noma izinto ezisebenzayo, i-HPMC ingase futhi ibambezele ukukhululwa kwezithako ezisebenzayo ngokwenza ifilimu yokuzivikela, ngaleyo ndlela yenza umphumela wokunakekelwa kwesikhumba uhlale isikhathi eside. Lesi sici sokukhululwa esibambezelekile asikwazi nje ukuthuthukisa umphumela wokusetshenziswa komkhiqizo, kodwa futhi sinciphise ukucasuka okungenzeka kwezithako ezisebenzayo esikhumbeni, ngaleyo ndlela sithuthukise isipiliyoni somsebenzisi.
8. Umsebenzi we-Antioxidant kanye nezinzile eshalofini
Ngenxa yokuthi i-HPMC ingakha ifilimu evikelayo, ikakhulukazi emikhiqizweni yokunakekelwa komuntu siqu, ingadlala indima ethile ye-antioxidant futhi ibambezele ukubola kwezithako ezithile ezine-oxidized kalula emkhiqizweni. Lokhu kuvumela imikhiqizo yokunakekelwa komuntu siqu equkethe i-HPMC ukuthi ibe nempilo yeshelufu ende futhi igcine ukusebenza kwayo ngesikhathi sokusetshenziswa.
9. Njenge-ejenti emisayo kanye ne-ejenti ehlakazayo
I-HPMC ingasetshenziswa futhi njenge-ejenti emisayo kanye ne-ejenti ehlakazayo ukuvimbela izinhlayiya eziqinile ukuthi zingahlali emikhiqizweni ewuketshezi. Isibonelo, kwezinye izihlanzi noma izikhuhla zomzimba eziqukethe izinhlayiya zokukhuhla, i-HPMC ingasabalalisa ngokulinganayo lezi zinhlayiya ukugwema inkinga yokunqwabelana kwezinhlayiyana noma imvula ngesikhathi sokusetshenziswa. Lo mphumela wokumiswa wenza umkhiqizo ufane futhi uqinisekisa imiphumela engaguquki njalo lapho usetshenziswa.
10. Isicelo ku izimonyo
I-HPMC ijwayele ukusetshenziswa emikhiqizweni yezimonyo, njengesisekelo, i-lipstick kanye ne-mascara. Njengefilimu yangaphambili, ingasiza izimonyo ukuthi zibambelele kangcono ebusweni besikhumba noma izinwele futhi zelule ukuqina kwezimonyo. Kumascara, i-HPMC ingakhuphula ukugoqa nokujiya kwezinkophe, kuyilapho isisekelo, isiza ukusabalalisa ama-pigments ngokulinganayo ukwenza izimonyo zibe ngokwemvelo.
Njengempahla eluhlaza esebenzayo, i-HPMC isetshenziswa kakhulu emikhiqizweni yokunakekela umuntu ngenxa yezakhiwo zayo ezinhle kakhulu zokwakha ifilimu, ukuqina nokuswakama. I-HPMC idlala indima ebalulekile kukho konke kusukela ekunakekelweni kwesikhumba okuyisisekelo kanye nemikhiqizo yokunakekelwa kwezinwele kuye kwezimonyo nezimonyo ezisezingeni eliphezulu. Njengoba isidingo sabathengi sobumnene nokusebenza ngempumelelo kwemikhiqizo siqhubeka nokwanda, ububanzi bokusebenza be-HPMC kulindeleke ukuthi bukhule ngokuqhubekayo. Akukwazi nje ukuthuthukisa umuzwa womkhiqizo, kodwa futhi ithuthukise ukuzinza nokuphepha kwefomula, ilethe ukuqamba okusha kanye namathuba okuthuthukiswa emikhiqizweni yokunakekelwa komuntu siqu.
