1. Ukwethulwa okuyisisekelo kwe-HPMC
I-HPMC (Hydroxypropyl Methylcellulose)iyinhlanganisela ye-polymer yokwenziwa etholakala ku-cellulose yemvelo. Ikhiqizwa ikakhulukazi ukuguqulwa kwamakhemikhali we-cellulose futhi isetshenziswa kabanzi kwezokwelapha, ukudla, izimonyo kanye nokwakhiwa. Ngenxa yokuthi i-HPMC ayincibiliki emanzini, ayinabo ubuthi, ayinambitheki futhi ayicunuli, isibe isithako esibalulekile emikhiqizweni eminingi.
Embonini yezemithi, i-HPMC ivamise ukusetshenziselwa ukulungisa amalungiselelo okukhishwa okuqhubekayo kwezidakamizwa, amagobolondo amaphilisi, neziqinisi zezidakamizwa. Ibuye isetshenziswe kabanzi ekudleni njenge-thickener, emulsifier, i-humectant kanye ne-stabilizer, futhi isetshenziswa njengesithako esinekhalori ephansi kwezinye izidlo ezikhethekile. Ngaphezu kwalokho, i-HPMC iphinde isetshenziswe njengesithako esijiyile futhi esithambisayo kuzimonyo.
2. Umthombo kanye nokwakheka kwe-HPMC
I-HPMC iyi-ether ye-cellulose etholwe ngokuguqulwa kwamakhemikhali kwe-cellulose yemvelo. I-Cellulose ngokwayo iyi-polysaccharide ekhishwe ezitshalweni, eyenza ingxenye ebalulekile yezindonga zamaseli ezitshalo. Lapho kuhlanganiswa i-HPMC, amaqembu ahlukene asebenzayo (afana ne-hydroxypropyl ne-methyl) ayaziswa ukuze kuthuthukiswe ukunyibilika kwayo kwamanzi kanye nezakhiwo ezijiya. Ngakho-ke, umthombo we-HPMC yizinto ezisetshenziswayo zezitshalo zemvelo, futhi inqubo yayo yokuguqula iyenza incibilike kakhulu futhi iguquguquke.
3. Ukusetshenziswa kwe-HPMC kanye nokuxhumana nomzimba womuntu
Inkambu yezokwelapha:
Embonini yezemithi, ukusetshenziswa kwe-HPMC kubonakala kakhulu emalungiselelweni okukhishwa kwezidakamizwa okuqhubekayo. Njengoba i-HPMC ingakha isendlalelo sejeli futhi ilawule ngempumelelo izinga lokukhululwa komuthi, isetshenziswa kabanzi ekuthuthukisweni kwezidakamizwa ezikhishwa njalo nezikhishwa okulawulwayo. Ngaphezu kwalokho, i-HPMC iphinde isetshenziswe njengegobolondo le-capsule lezidakamizwa, ikakhulukazi kuma-capsules ezitshalo (amaphilisi emifino), lapho ingakwazi ukuthatha indawo ye-gelatin yezilwane zendabuko futhi inikeze inketho evumela imifino.
Ngokombono wokuphepha, i-HPMC ithathwa njengephephile njengesithako somuthi futhi ngokuvamile inokuvumelana okuhle kwezinto eziphilayo. Ngenxa yokuthi ayinabo ubuthi futhi ayizwakali emzimbeni womuntu, i-FDA (US Food and Drug Administration) igunyaze i-HPMC njengesengezo sokudla kanye nesamukeli sezidakamizwa, futhi azikho izingozi zezempilo ezibangelwa ukusetshenziswa kwesikhathi eside ezitholakele.
Imboni yokudla:
I-HPMC isetshenziswa kakhulu embonini yokudla, ikakhulukazi njenge-thickener, stabilizer, emulsifier, njll. Isetshenziswa kabanzi ekudleni okulungele ukudliwa, iziphuzo, amaswidi, imikhiqizo yobisi, ukudla kwezempilo neminye imikhiqizo. I-HPMC ibuye isetshenziswe kaningi ekukhiqizeni imikhiqizo enekhalori ephansi noma enamafutha aphansi ngenxa yezakhiwo zayo ezincibilikayo emanzini, okuthuthukisa ukunambitheka nokuthungwa.
I-HPMC ekudleni itholakala ngokuguqulwa kwamakhemikhali esitshalweni se-cellulose, futhi ukugxila kwayo kanye nokusetshenziswa kwayo kuvame ukulawulwa ngokuqinile ngaphansi kwamazinga okusetshenziswa kwezithasiselo zokudla. Ngokocwaningo lwamanje lwesayensi namazinga okuphepha kokudla emazweni ahlukahlukene, i-HPMC ithathwa njengephephile emzimbeni womuntu futhi ayinakho ukusabela okubi noma ubungozi bezempilo.
Imboni yezimonyo:
Ezimonyoni, i-HPMC ivamise ukusetshenziswa njenge-thickener, emulsifier and moisturizing ingredient. Isetshenziswa kakhulu emikhiqizweni efana namakhilimu, izinto zokuhlanza ubuso, okhilimu wamehlo, izindebe zomlomo, njll. ukulungisa ukuthungwa nokuzinza komkhiqizo. Ngenxa yokuthi i-HPMC imnene futhi ayicasuli isikhumba, ithathwa njengesithako esifanele zonke izinhlobo zesikhumba, ikakhulukazi isikhumba esibucayi.
I-HPMC iphinde isetshenziswe kumafutha kanye nemikhiqizo yokulungisa isikhumba ukusiza ukuthuthukisa ukuzinza nokungena kwezithako zezidakamizwa.
4. Ukuphepha kwe-HPMC emzimbeni womuntu
Ukuhlolwa kwe-Toxicological:
Ngokocwaningo lwamanje, i-HPMC ithathwa njengephephile emzimbeni womuntu. I-World Health Organization (WHO), i-Food and Agriculture Organization (FAO), kanye ne-US FDA bonke benze ukuhlolwa okuqinile ngokusetshenziswa kwe-HPMC futhi bakholelwa ukuthi ukusetshenziswa kwayo emithini nasekudleni lapho kugxilwe khona ngeke kube nomthelela empilweni yabantu. I-FDA ibala i-HPMC njengento “evame ukubonwa njengephephile” (GRAS) futhi iyivumela ukuthi isetshenziswe njengesithasiselo sokudla kanye nesamukeli sezidakamizwa.
Ucwaningo lomtholampilo nokuhlaziywa kwecala:
Ucwaningo oluningi lwezokwelapha luye lwabonisa lokhoI-HPMCayibangeli ukusabela okubi noma imiphumela engemihle phakathi kwebanga elivamile lokusetshenziswa. Isibonelo, uma i-HPMC isetshenziswa ekwenziweni kwemithi, iziguli ngokuvamile azibonisi ukungezwani komzimba noma okunye ukungaphatheki kahle. Ngaphezu kwalokho, azikho izinkinga zempilo ezibangelwa ukusetshenziswa ngokweqile kwe-HPMC ekudleni. I-HPMC iphinde ibhekwe njengephephile kubantu abathile abakhethekile ngaphandle uma kukhona ukungezwani okukodwa kwezithako zayo.
Ukungezwani komzimba kanye nemiphumela emibi:
Nakuba i-HPMC ingavamisile ukubangela ukungezwani komzimba, inombolo encane yabantu abazwela kakhulu ingase ibe nokungezwani nayo. Izimpawu zokungezwani komzimba zingase zihlanganise ububomvu besikhumba, ukulunywa, nobunzima bokuphefumula, kodwa izimo ezinjalo azivamile kakhulu. Uma ukusetshenziswa kwemikhiqizo ye-HPMC kubangela noma yikuphi ukungakhululeki, yeka ukuyisebenzisa ngokushesha futhi uxhumane nodokotela.
Imiphumela yokusetshenziswa kwesikhathi eside:
Ukusetshenziswa kwesikhathi eside kwe-HPMC ngeke kubangele noma yimiphi imiphumela emibi eyaziwayo emzimbeni womuntu. Ngokocwaningo lwamanje, abukho ubufakazi bokuthi i-HPMC izodala umonakalo ezithweni ezifana nesibindi nezinso, futhi ngeke ithinte amasosha omzimba womuntu noma ibangele izifo ezingapheli. Ngakho-ke, ukusetshenziswa kwesikhathi eside kwe-HPMC kuphephile ngaphansi kwamazinga akhona okudla nemithi.
5. Isiphetho
Njengenhlanganisela etholakala ku-cellulose yezitshalo zemvelo, i-HPMC isetshenziswa kabanzi emikhakheni eminingi efana nemithi, ukudla kanye nezimonyo. Inani elikhulu lezifundo zesayensi nokuhlola okunobuthi kubonise ukuthi i-HPMC iphephile phakathi kwebanga elifanele lokusetshenziswa futhi ayinabo ubuthi obaziwayo noma izingozi ze-pathogenic emzimbeni womuntu. Kungakhathaliseki ukuthi kumalungiselelo emithi, izithasiselo zokudla noma izimonyo, i-HPMC ithathwa njengesithako esiphephile nesisebenzayo. Vele, ngokusetshenziswa kwanoma yimuphi umkhiqizo, imithethonqubo efanele yokusetshenziswa kufanele isalandelwa, ukusetshenziswa ngokweqile kufanele kugwenywe, futhi ukunakwa okuseduze kufanele kukhokhwe ukusabela okungenzeka komuntu ngamunye kwe-allergies ngesikhathi sokusetshenziswa. Uma unezinkinga zempilo ezikhethekile noma ukukhathazeka, kunconywa ukuthi uthintane nodokotela noma uchwepheshe.
