Yethula:
Eminyakeni yamuva nje, imboni yokunakekelwa kwesikhumba ibone ukwanda kokusetshenziswa kwezithako ezihlukahlukene ezintsha nezizuzisayo.Esinye isithako esinakwa kakhulu yi-titanium dioxide (I-TiO2).Njengoba yaziwa kabanzi ngenxa yemisebenzi yayo eminingi, lesi sakhi samaminerali sesenze izinguquko endleleni esinakekela ngayo isikhumba.Kusukela emandleni ayo okuvikela ilanga kuya ezinzuzweni zayo ezingcono kakhulu zokuthuthukisa isikhumba, i-titanium dioxide isiphenduke isimangaliso sesikhumba.Kulokhu okuthunyelwe kwebhulogi, singena sijula emhlabeni we-titanium dioxide futhi sihlola ukusetshenziswa kwayo nezinzuzo eziningi ekunakekeleni isikhumba.
I-Mastery of the Sun's Shield:
I-Titanium dioxideyaziwa kabanzi ngokusebenza kwayo ekuvikeleni isikhumba sethu emisebeni ye-UV eyingozi.Lesi sakhi samaminerali sisebenza njengesivikelo elangeni esingokoqobo, sakha umgoqo obonakalayo ebusweni besikhumba obonisa futhi ohlakaze imisebe ye-UVA ne-UVB.I-Titanium dioxide inokuvikela okubanzi okuvikela isikhumba sethu emonakalweni obangelwa ukuchayeka elangeni isikhathi eside, esiza ekuvimbeleni ukushiswa yilanga, ukuguga ngaphambi kwesikhathi, ngisho nomdlavuza wesikhumba.
Ngaphandle kokuvikela ilanga:
Nakuba i-titanium dioxide yaziwa kakhulu ngezici zayo zokuvikela ilanga, izinzuzo zayo zidlulela ngale kwezindawo zayo zokuvikela ilanga.Le nhlanganisela ehlukahlukene iyisithako esivamile emikhiqizweni ehlukahlukene yokunakekelwa kwesikhumba, okuhlanganisa isisekelo, impushana, ngisho ne-moisturizer.Inikeza ukufakwa okuhle kakhulu, isiza ngisho nethoni yesikhumba futhi ifihle ukungapheleli.Ngaphezu kwalokho, i-titanium dioxide inamandla amahle kakhulu okusabalalisa ukukhanya, okwenza ibala likhazimule futhi lidume phakathi kwabathanda izimonyo.
Ilungele isikhumba futhi iphephile:
Isici esiphawulekayo se-titanium dioxide ukuhambisana kwayo okuphawulekayo nezinhlobo ezahlukene zesikhumba, kuhlanganise nesikhumba esibucayi nesithandwa yizinduna.Akuyona i-comedogenic, okusho ukuthi ngeke ivale ama-pores noma ibe yimbi nakakhulu ukuphuma.Imvelo emnene yalesi sakhi iyenza ifanelekele abantu abanesikhumba esisebenzayo noma esicasuliwe, okubavumela ukuba bajabulele izinzuzo zayo eziningi ngaphandle kwemiphumela emibi.
Ukwengeza, iphrofayili yokuphepha ye-titanium dioxide ithuthukisa nakakhulu ukukhanga kwayo.Kuyisithako esigunyazwe yi-FDA esithathwa njengephephile ukuze sisetshenziswe abantu futhi sitholakala emikhiqizweni eminingi yokunakekelwa kwesikhumba ethengiswayo.Kodwa-ke, kufanelekile ukuqaphela ukuthi i-titanium dioxide efomini le-nanoparticle ingase ibe isihloko socwaningo oluqhubekayo mayelana nemiphumela engaba khona empilweni yomuntu.Njengamanje, abukho ubufakazi obanele bokunquma ngokuqinisekile noma yiziphi izingozi ezihlobene nokusetshenziswa kwayo emikhiqizweni yokunakekelwa kwesikhumba.
Ukuvikelwa kwe-UV okungalandeleki:
Ngokungafani nama-sunscreens avamile avame ukushiya uphawu olumhlophe esikhumbeni, i-titanium dioxide inikeza isisombululo esijabulisa kakhulu.Ukuthuthuka kwezinqubo zokukhiqiza i-titanium dioxide kubangele usayizi wezinhlayiyana ezincane, okubenza bacishe bangabonakali lapho besetshenziswa.Le ntuthuko ivula indlela yamafomula abukeka kahle ahlangabezana nezidingo zalabo abafuna isivikelo esanele selanga ngaphandle kokuphazamisa ukubukeka kwebala labo.
Ekuphetheni:
Akungabazeki ukuthi i-titanium dioxide isiyisithako esibalulekile nesithandwayo ekunakekelweni kwesikhumba.Ikhono layo lokuhlinzeka ngokuvikelwa kwe-UV ebanzi, ukuthuthukisa ukubukeka kwesikhumba, nokuhambisana nezinhlobonhlobo zezinhlobo zesikhumba kugqamisa ukuguquguquka nokusebenza kwayo okuhlukahlukene.Njenganoma yisiphi isithako sokunakekelwa kwesikhumba, kufanele sisetshenziswe njengokuqondiswa nokunaka noma yikuphi ukuzwela komuntu siqu.Ngakho-ke yamukela izimangaliso ze-titanium dioxide futhi ukwenze okuyisisekelo esimisweni sakho sokunakekela isikhumba ukuze unikeze isikhumba sakho ungqimba olwengeziwe lwesivikelo.
