Wake walufunda uhlu lwezithako zebha yensipho, i-face wash, noma i-body lotion oyisebenzisayo? Uma wenza kanjalo, elinye lamagama ozolibona njalo yi-"glycerin." Nakuba abaningi bethu belubonile leli gama, asazi kahle ukuthi liyini i-glycerin nokuthi linenzuzo enjani ngempela emizimbeni yethu, ikakhulukazi esikhumbeni sethu. Ngakho-ke namuhla, ake sixoxe ngale glycerin.
Ngakho-ke, iyini ngempela i-glycerin?
Kalula nje, i-glycerin iyi-carbohydrate eyingxenye yohlobo oluthile lukashukela. Ngokwezokwelapha, ibizwa ngokuthi i-sugar alcohol noma i-polyol. Iwuketshezi oluqinile olungenaphunga, olunambitheka kamnandi. Ifana nesiraphu.
I-Glycerin ikhiqizwa ngokwemvelo ngokubiliswa koshukela ezihlahleni nasezivinini. Kodwa-ke, iningi le-glycerin esiyisebenzisayo namuhla likhiqizwa ngokufaka amafutha ezilwane noma emifino kanye namafutha enqubo ekhethekile yamakhemikhali.
Ukukhiqizwa kokuqala kwe-glycerin kubantu kwaqoshwa ngo-1779. Kwatholakala ngengozi ngusokhemisi waseSweden ogama lakhe lingu-KW Scheele ngesikhathi ebilisa uwoyela womnqumo kanye nekhemikhali equkethe i-lead. Waqamba uketshezi olujiyile nolumnandi ngokuthi "glycerol" ngemuva kwegama lesiGreki elithi "glykos" elisho ubumnandi.
I-glycerin esetshenziswa emikhiqizweni eminingi emakethe namuhla ihlanzekile ngo-95%. Izinhlangano ezinkulu zezempilo emhlabeni jikelele, njenge-U.S. Food and Drug Administration (FDA), ziqinisekisile ukuthi i-glycerin iphephile ukusetshenziswa ngabantu.
Ziyini izinzuzo zezempilo ze-glycerin?
I-Glycerin inezindlela eziningi ezahlukene zokusebenzisa. Ake sibheke izinzuzo eziyinhloko.
Izinzuzo ezimangalisayo zesikhumba sethu
Ubuwazi ukuthi i-glycerin ingenye yezindlela zokugcoba isikhumba ezisebenza kahle kakhulu? Kwezokwelapha, siyibiza ngokuthi i-humectant. Okusho ukuthi, i-ejenti engadonsa umhwamuko wamanzi endaweni ezungezile futhi igcine umswakama lapho ukhona .
Cabanga nje, uma isikhumba sakho somile futhi siqhekekile, uma ufaka ukhilimu oqukethe i-glycerin, okwenziwa yi-glycerin ukukhipha umswakama emoyeni bese kuwuletha esikhumbeni sakho. Futhi kunciphisa ukuhwamuka komswakama ngaphakathi kwesikhumba.
Ingqimba engaphandle yesikhumba sethu ibizwa ngokuthi i-stratum corneum. Lolu ngqimba lubaluleke kakhulu ekugcineni umswakama emzimbeni. Ucwaningo luthole ukuthi i-glycerin yandisa amandla okugcina umswakama walolu ngqimba lwe-stratum corneum. Akukhona lokho kuphela, i-glycerin iyasiza futhi ekuvikeleni isikhumba kwezinye izinto ezicasulayo esikhumbeni. Futhi, le mpahla yokuthambisa isiza ekwelapheni amanxeba esikhumba ngokushesha.
Ukukhululeka ekuqunjelweni
I-Glycerin inezakhiwo zokuhlanza isisu, okusho ukuthi ikhulula indle futhi yenza kube lula ukudlula . Ngenxa yalesi sizathu, i-glycerin isetshenziswa futhi njengokwelapha abantu abanokuqunjelwa. Lokhu kuvame ukuza ngesimo sama -suppository afakwa e-rectum.
Lokhu kusebenza ngokudonsa amanzi endle eqinile emathunjini, kuyayithambisa, futhi kusize imisipha emathunjini ukuthi ikhiphe udoti kalula. Kodwa-ke, akuwona umqondo omuhle ukuqhubeka nokusebenzisa lokhu ngaphandle kweseluleko sezokwelapha.
Ukuthuthukisa amakhono abadlali
Ucwaningo oluthile lukhombisile ukuthi i-glycerin ingathuthukisa ukusebenza kwezemidlalo. Njengoba i-glycerin isiza umzimba ukuthi ugcine amanzi, ingaba wusizo kubasubathi, ikakhulukazi ezimweni lapho kungenzeka khona ukuphelelwa amanzi emzimbeni. Kodwa-ke, lokhu kugcinwa kwamanzi kungaholela ekwandeni okuncane kwesisindo somzimba. Ezinye izifundo zikhombisile nokuthi i-glycerin, uma ithathwa nezinye izithako, njenge-creatine, ithuthukisa ukusebenza kwenhliziyo nemithambo yegazi.
Lapho i-glycerin isetshenziswa khona ekuphileni kwansuku zonke
I-Glycerin iyisithako esitholakala yonke indawo. Isetshenziswa ezintweni eziningi, kusukela ezimonyweni kuya ekudleni naseziphuzweni kuya emithini . Ngokusho kombiko we-FDA, i-glycerin iyisithako esisetshenziswa kakhulu ezimonyweni ngemuva kwamanzi namakha.
Ake sibheke izindawo eziyinhloko lapho kusetshenziswa khona i-glycerin kanye nezibonelo ezithile kuthebula elingezansi.
| Insimu yokusetshenziswa | Izibonelo |
|---|---|
| Imikhiqizo yokunakekelwa kwesikhumba nobuhle | Insipho, insipho yokugeza, iloshini yomzimba, ukhilimu wobuso, i-lipstick, umbala wezinwele, ukhilimu wokushefa, i-hair conditioner, imikhiqizo yezingane. |
| Imboni yokudla | Njengesithako esimnandi ku-toffee, ushokoledi kanye ne-confectionery, ukugcina ukuthungwa okubushelelezi kwe-ayisikhilimu kanye ne-toothpaste, kanye nesilondolozi sokudla. |
| Imithi | Amasiraphu okukhwehlela, amafutha ahlukahlukene, izibulala-zinhlungu, amakhaphu emithi, kanye nama-suppositories okuqunjelwa. |
| Ukwelashwa okukhethekile | Inikezwa ngemithambo yegazi ukuze kuncishiswe ukucindezeleka kwamehlo ezimweni lapho ukucindezeleka kwamehlo kukhula khona, njenge-glaucoma, kanye nokunciphisa ukucindezeleka ebuchosheni ezifweni zobuchopho, njenge-meningitis kanye ne-encephalitis. |
Ingabe kukhona imiphumela emibi yokusebenzisa i-glycerin?
Nakuba i-glycerin ngokuvamile iphephile kakhulu, ayivamile ukubangela ukusabela kokungezwani komzimba kwabanye abantu. Isibonelo, abanye abantu bangase babe nokuqubuka, noma ukucasuka kwesikhumba, lapho into equkethe i-glycerin ithinta isikhumba sabo.
Odokotela ngezinye izikhathi benza ukuhlolwa kwe-patch ukuze bahlole ukuthi isikhumba sakho sibucayi yini. Lokhu kuhilela ukufaka inani elincane le-glycerin endaweni encane yesikhumba sakho bese ulinda amahora ambalwa ukuze ubone ukuthi kukhona yini ukusabela okungekuhle. Ngakho-ke kuwumqondo omuhle ukwenza ukuhlolwa kwe-patch ngaphambi kokusebenzisa umkhiqizo omusha.
Singayitholaphi i-glycerin emsulwa?
Ungathenga uketshezi lwe-glycerin oluhlanzekile emakhemisi noma kwezinye izitolo. Ngokuvamile awudingi incwadi kadokotela ukuze uluthole.
Kodwa into ebaluleke kakhulu okufanele uyikhumbule lapha ukuthi ngaphambi kokusebenzisa i-glycerin nganoma yiluphi uhlobo (ukuyifaka esikhumbeni sakho noma ukuyiphuza), kufanele nakanjani ukhulume nodokotela wakho futhi ucele iseluleko.
Ikakhulukazi uma usebenzisa i-glycerin ngesimo esifana nokuqunjelwa noma esinye isizathu sezokwelapha, ukwenza kanjalo ngaphandle kweseluleko sezokwelapha kungabangela izinkinga zempilo ezingadingekile.
Umlayezo Wokuya Nawe Ekhaya
- I-Glycerin iwuketshezi olunokunambitheka okumnandi nolujiyile olusetshenziswa kakhulu ekuphileni kwethu kwansuku zonke ezinsipho, okhilimu, ukudla kanye nemithi.
- Isici sayo esiyinhloko ukuthi isebenza njenge-humectant, yingakho i-glycerin isiza ekuvimbeleni ukoma kwesikhumba futhi isigcine siphilile.
- I-Glycerin isetshenziselwa futhi ukuqeda ukuqunjelwa nokuthuthukisa ukusebenza kwabanye abasubathi.
- Nakuba i-glycerin ivame ukuphephile, ayivamile ukubangela ukungezwani komzimba.
- Ungasebenzisi i-glycerin (ikakhulukazi ngokuyiphuza) ngaphandle kweseluleko sezokwelapha nganoma yisiphi isizathu. Njalo xhumana nodokotela wakho ngaphambi kokusebenzisa noma yini.
