Kule ndatshana, sizobhekisisa uwoyela wembewu kaloti, siphinde sihlole ubufakazi obuzungeze isimangalo sayo sokuvikelwa kwelanga.
Uyini uwoyela wesanqante futhi ziyini izinzuzo zawo?
Amafutha wekharothi imbewu ngamafutha abalulekile angasetshenziswa esikhunjeni, uma exutshwe nophethiloli othwala. Kususelwa enzalweni yesitshalo seDaucus carota.

Ama-sunscreen alungiselelwe ukuhweba ngokuvamile abhalwe inombolo ekhombisa ukuvikelwa kwelanga (SPF). I-SPF isho isikhathi ongasichitha elangeni ngaphambi kokuba imisebe ye-UVB iqale ukubomvu futhi ishise isikhumba sakho.
Ukusetshenziswa kwesikrini esivikela ilanga esiqukethe okungenani i-SPF engu-15, ngaphezu kwezinye izindlela zokuzivikela, njengokugqoka isigqoko esinomphetho obanzi. Abanye odokotela besikhumba bancoma ukusebenzisa kuphela ama-SPF angama-30 noma ngaphezulu.
Ngaphezu kwe-SPF, kubalulekile ukusebenzisa i-sunscreen ebanzi. Lokhu kusho ukuthi ivikela imisebe ye-UVA ne-UVB. I-UVA ne-UVB yizinhlobo ezimbili zemisebe ye-ultraviolet evela elangeni.
Imisebe ye-UVB ibangela ukushiswa yilanga. Imisebe ye-UVA idala isithombe, futhi ikhulisa nemiphumela ebanga umdlavuza ye-UVB. Ngokungafani nesivikelo selanga, ukuvimbela ilanga kuvikela isikhumba sakho emisebeni ye-UVB kuphela.
I-SPF yamafutha esanqante
Ngakho-ke, ingabe uwoyela wembewu yesanqante uyawenza umsebenzi wesikrini selanga esiphezulu se-SPF? Ngaphandle kocwaningo lwango-2009 oluthi luyakwenza, impendulo ithi cha.
Ucwaningo, olushicilelwe kwiFarmacognosy Magazine, luhlolisise ama-sunscreen angashiwongo ngegama, athengwe ngumsabalalisi oyedwa ozinze eRaipur, eChhattisgarh, eNdiya.
Uhlu oluphelele lwezithako zesikrini selanga ngasinye aludalulwanga. Ngalesi sizathu, akunakwenzeka ukwazi ukuthi yisiphi isithako esikhiqize umphumela we-SPF.
Lolu cwaningo oluncane kakhulu futhi aluzange lucacise ukuthi yiluphi uhlobo lwamafutha esanqante ama-sunscreen aqukethe, lubhalwe kuphela njengeDaucus carota. Uwoyela wesanqante, ongowoyela wesithwali hhayi owoyela obalulekile, unamandla amancane okuvikela isikhumba elangeni. Kodwa-ke ayinayo i-SPF eyaziwa futhi akufanele isetshenziswe njengesivikelo selanga.
Ayikho i-SPF eyaziwayo
Njengamafutha esanqante, uwoyela wesanqante obalulekile awunayo i-SPF, futhi akufanele isetshenziswe njengesikrini selanga.
Azikho ezinye izifundo ezibonisa ukuthi isanqante imbewu kawoyela obalulekile noma uwoyela wesanqante unikela ngokuvikelwa okukhulu elangeni.
Uwoyela wembewu kaloti osetshenziswa njengesithambisi emikhiqizweni yokuvikela imisebe yelanga
Okungeze ekudidekeni kwabathengi kungaba yinani lemikhiqizo equkethe uwoyela wembewu kaloti njengesithako. Le mikhiqizo imvamisa ifaka uwoyela wembewu yesanqante ngezinzuzo zayo zokuthambisa, hhayi amandla ayo okuvikela imisebe ye-UVA ne-UVB.
Ngabe uwoyela wesanqante ungasebenza njengamafutha okushuka?
Njengoba uwoyela wembewu yesanqante ungowoyela obalulekile, awunakusetshenziswa esikhunjeni sakho ngamandla aphelele. Njengawo wonke amafutha abalulekile, uwoyela wembewu yesanqante kumele uxutshwe nowoyela othwala ngaphambi kokufaka izihloko. Ngalesi sizathu, ngeke isetshenziswe njengamafutha okushuka.

Amanye amafutha okushuka kanye nama-accelerators okushuka afaka kuhlu uwoyela wezinhlanyelo njengesithako, kodwa ulapho ukuthambisa isikhumba, hhayi ukusivikela elangeni. Le mikhiqizo ingafaka futhi uwoyela wesanqante, ovame ukudideka ngamafutha esanqante.
Amafutha e-carrot seed akhishwe enzalweni yesitshalo se-Daucus carota, kanti u-carrot uwoyela wenziwa ngoqathe ochotshoziwe. Uwoyela karoti kwesinye isikhathi usetshenziswa njengesithako samafutha okushuka njengamabala esikhumba, ngoba angangeza ithusi elincane, noma umbala wewolintshi esikhunjeni.
Ngabe kukhona ezinye izivikelo zemvelo zemvelo ezingasebenza esikhundleni salokho?
Sekudlule amashumi eminyaka kusukela i-Food and Drug Administration (FDA) ikhipha imihlahlandlela emisha yokuphepha kwe-sunscreen.

Zombili lezi zithako zingamaminerali.
Ngisho ngokusebenzisa i-zinc oxide ne-titanium oxide kukhona amakhemikhali, izivikeli zelanga eziqukethe zona kuvame ukubizwa ngokuthi zemvelo, noma ezomzimba. Lokhu kusho ukuthi izithako azingeni esikhunjeni kepha zivimbela ilanga ngokuhlala phezu kwesikhumba.
Ama-sunscreen emvelo aqukethe amaminerali ahlinzeka ngama-SPF ahlukahlukene, njengoba kukhonjisiwe kwilebula yabo. Zihlukile ku-DIY nakwezinye izivikelo zelanga ezenziwe ngama-oyela, amajusi, noma izimpushana zejusi yezithelo, njengoba lokhu kunikeza ukuvikeleka okuncane kakhulu noma kunganiki langeni.
I-FDA ihlela ukukhipha imithetho eyengeziwe yama-sunscreen amakhemikhali kanye nenqubo yabo yokulebula ngasekupheleni konyaka, ngemuva kokuthi behlolisise izithako ezi-12 zesigaba sesithathu selanga, kufaka phakathi i-oxybenzone. Isigaba III sisho ukuthi ayikho idatha eyanele yesayensi ukukhombisa ukuthi ziphephile yini ukusebenzisa noma cha.
Ukwehla kwe-oxybenzone
I-Oxybenzone itholakale emanzini omhlaba, nase-coral reef bleaching and coral death. Iphinde yamunca esikhunjeni, futhi itholakale ku-amniotic fluid, i-plasma yegazi, umchamo, nobisi lwebele lomuntu.
I-Oxybenzone futhi iyisiphazamisi se-endocrine, esingathinta kabi amasistimu ama-hormone abesilisa, abesifazane nezingane. Ngaphezu kwalokho, ixhunyaniswe nesisindo sokuzalwa esiphansi, ukungezwani komzimba, nokulimala kwamaseli.
Ukudla okudlela endlini
Uma ufana nabantu abaningi, ufuna ukujabulela ukuphuma elangeni ngaphandle kokukhathazeka ngokushiswa yilanga, ukufotwa isithombe, nomdlavuza wesikhumba. Uma isetshenziswe kahle, i-sunscreen ebanzi ebanzi ene-SPF engu-15 noma ngaphezulu izokusiza ukwenza lokho.
Kodwa-ke, ama-sunscreen amaningi aqukethe amakhemikhali afana ne-oxybenzone, angena emzimbeni futhi angaba nemiphumela emibi yezempilo eyabo. Ngalesi sizathu, intshisekelo yokusebenzisa uwoyela wemvelo njengezikrini zelanga seyinyukile. Enye yazo ngamafutha esanqante.
Kodwa-ke, ngaphandle kocwaningo olulodwa olushicilelwe, abukho ubufakazi besayensi bokuthi u-carrot seed oil unikeza noma yikuphi ukuvikelwa elangeni.
