Ngaba i-Nanoparticles ikhuselekile? Kwaye bebanjani kwi-Sunscreen yami?
Uye wagqiba ekubeni ukusebenzisa i- sunscreen yemvelo kukukhetha okulungileyo. Mhlawumbi unomuva wokukhetha impilo enempilo yakho nakwimo yendalo, okanye i-sunscreen enezakhi ezisebenzayo zenzakalisa isikhumba sakho so-so-sensitive.
Emva koko uva nge "nanoparticles" kwezinye iindawo zokukhanya kwelanga, kunye nolunye ulwazi olumangalisa nolwaluphikisanayo malunga neengqungquthela ezikwenza ukuba ume.
Ngokukrakra, ukhetha i-sunscreen yendalo kufuneka idideke?
Ngeenkcukacha ezininzi apho, kunokubonakala kunzima. Ngoko-ke, masinqumle ingxolo size sibheke ukujonga ngokungabonakali kwamanoparticles e-sunscreen, ukhuseleko lwabo, izizathu zokuba uza kuzifuna kwi-sunscreen yakho kwaye xa ungafuni.
Ziziphi iiNanoparticles?
I-nanoparticles ziyingqungquthela ezincinci zezinto ezikhoyo. I-nanoparticles ingaphantsi kwama-nanometer angama-100. Ukuze unikele ngombono othile, i-nanometer ingama-1000 amancinci ngaphezu kobunzima bomnxeba omnye.
Nangona i-nanoparticles ingadalwa ngokwemvelo, njengamaconsi amancinci olwandle oluthileyo, umzekelo, ezininzi ze-nanoparticles zenziwe kwibhuyibhile. Nge-sunscreen, i-nanoparticles enombuzo i-zinc oxide kunye ne-titanium dioxide. Ezi zithako zidilizwe zibe ziincinci ezintle ngaphambi kokuba zongezwe kwi-sunscreen yakho.
I-Nanoparticles yaqala ukufumaneka kwi-sunscreens kwiminyaka yee-1980, kodwa ayizange ibambelele kude kube ngama-1990.
Namhlanje, unokuthi uthathe i-sunscreen yakho yendalo kunye ne-zinc oxide kunye / okanye i-titanium dioxide ayi-particle nano-size ngaphandle kokuba kuchazwe ngenye indlela.
Amagama athi "nano" kunye "ne-micronized" ayafana. Ngoko, ukuvelisa i-sunscreen ephethe "i-oxygen zinc oxide" okanye "i-titanium dioxide" yileta iqukethe i-nanoparticles.
I-nanoparticles ayifumaneki nje kwi-sunscreens.
Unonophelo loluninzi lweemveliso kunye neemveliso zokuzongcola, njengezisekelo, i-shampoos, kunye ne-toothpaste, kaninzi ziqukethe izithako ezinamatshini. I-nanoparticles nayo isetyenziswe kwikhompyutheni, iingubo, iglasi elingagxininisi, kunye nokunye.
I-Nanoparticles Gcina i-Sunscreens yemvelo ngokushiya i-White Film kwi-Skin yakho
Xa ukhetha i-sunscreen yakho yemvelo, unokukhetha ezimbini; abo abanama-nanoparticles kunye nabangenalo. Ukwahlula phakathi kwezi zibini kuya kubonakala kwesikhumba sakho.
Zombini i-titanium dioxide kunye ne-zinc oxide zivunyiwe yi-FDA njengezityalo zendalo zelanga . Banikezela ngamnye ukukhusela i-UV, nangona i-titanium dioxide isebenza kakuhle xa idibene ne-zinc oxide okanye esinye isithako se-sunscreen.
I-zinc oxide kunye nomsebenzi we-titanium dioxide ngokubonakalisa imisebe ye-UV kude nesikhumba, ikhusela ulusu elangeni. Kwaye zisebenza kakuhle.
Ngendlela yabo eqhelekileyo, engekho nano, i-zinc oxide kunye ne-titanium dioxide imhlophe. Xa zifakwe kwi-sunscreen, ziza kushiya ifilimu emhlophe e-opaque kwibala. Cinga ngesilondolozi sokulondolozwa ngokumhlophe nge-bridge kwi-pep-yep, leyo yi-zinc oxide.
Faka ama-nanoparticles. I-sunscreen eyenziwe nge-oxide ene-zinc ene-zinc kunye ne-titanium dioxide ibhaqa kwesikhumba kangcono, kwaye ayiyi kushiya i-pasty look.
I-nanoparticles e-ultra-fine yenza i-suncreen i-opaque encinci kodwa iphumelele.
Ubuninzi bePhando lubona iNanoparticles kwiSitrocreen Safe
Ukusuka oko sikuyazi ngoku, akubonakali ukuba i-nanoparticles ye-zinc oxide okanye i-titanium dioxide inobungozi nangayiphi na indlela. Nangona kunjalo igalelo lexesha elide lokusebenzisa i-oxygen yinc oxide kunye ne-titanium dioxide, yinto encane. Ngamanye amagama, abukho ubungqina bokuba ukusetyenziswa kwexesha elide likhuselekile ngokupheleleyo, kodwa akukho bungqina bokuba lunobungozi.
Abanye baye bacela ukukhuselwa kwezi ngqungquthela ezincinci. Ngenxa yokuba bancinci, banokubanjiswa ngesikhumba nasemzimbeni.
Ubungakanani obuninzi kwaye bunzulu kangakanani ukungena kwawo kuxhomekeke kwindlela encinci i-zinc oxide okanye i-titanium dioxide, kunye nendlela ehanjiswa ngayo.
Ukukhaba, kwenzeka ntoni emzimbeni wakho ukuba i-zinc oxide okanye i-titan dioxide i-nano-particles ifakwa? Ngelishwa, akukho mpendulo ecacileyo yolu, nokuba kunjalo.
Kukho ukucinga ukuba banokugxininisa nokulimaza iiseli zomzimba wethu, ukukhawuleza ukuguga ngaphakathi nangaphandle. Kodwa uphando olungakumbi lufuneka lwenziwe ukuba lukwazi ngokucacileyo ngenye indlela.
I-Titanium dioxide, xa ifomini yayo ifakile kunye ne- inhaled , iboniswe ukuba ibangele umdlavuza wamaphaphu kwiiriti zeebhabhi. I-micronised titanium dioxide iphinda ingene kancinci ngakumbi kunokuba ibe ne-oxygen zinc, kunye ne-titanium dioxide iboniswe ukuba idlule kwi-placenta kwaye ibhuloho isithintelo segazi.
Khumbula ke, ukuba ininzi yale nkcazelo ivela ekutheni i- titanium dioxide (kuba itholakala kwiindawo ezininzi zokutya kwangaphambili kunye neesekese). Ukususela kwizifundo ezininzi ze-titanium dioxide kunye ne-zinc oxide, i-zinc oxide, i-zinc oxide kuphela, ngezinye izihlandlo ezi zifunyanwa kwilusu, kwaye ke ngoko zibe ziphantsi kakhulu.
Oko kuthetha ukuba nangona usebenzisa i-sunscreen equkethe i-nanoparticles, bangenakuyithatha ikhefu lokuqala. Isixa esithathiweyo siyahluka kakhulu kuxhomekeke ekuqulunqeni kwesikrini, kwaye ezininzi zazo aziyi kuzinyamekela xa kunjalo.
Ngolwazi esilunalo ngoku, i-suncreen enama-nanoparticles ibonakala ikhuselekile kwaye isebenza kakuhle. Isicacileyo esicacileyo sisiphumo sokusetyenziswa kwexesha elide lomkhiqizo unakho kwimpilo yakho, ingakumbi ukuba usebenzisa le mveliso imihla ngemihla. Kwakhona, akukho bungqina bokuba ukusetyenziswa kwexesha elide le-oxyde yincidesi ye-zinc okanye i-titanium dioxide inobungozi, asikwazi nje ukuba yintoni umphumo (xa ikhona) kwesikhumba okanye emzimbeni wakho.
ILizwi
Okokuqala, khumbula ukuba ukugqoka i-sunscreen nsuku zonke ngenye yezinto ezintle ongayenza kwimpilo yexesha elide le-kliniki (kwaye yindlela efanelekileyo kakhulu yokuguga). Ngoko, kudos kuwe ukuba usebenze ekukhuseleni isikhumba sakho!
Kukho uninzi lwama-sunscreen yemvelo ekhoyo, zombini nano kunye nongenanto, kukho imveliso ngaphandle kwakho. Ukusebenzisa i-sunscreen nge-micronised (AKA nano-particle) i-zinc oxide okanye i-titanium dioxide iya kukunika umkhiqizo ongezantsi kwaye uhlambe ngokugcwele.
Ukuba uchaphazelekayo malunga ne-nano-particles, usebenzisa i-sunscreen engeyiyo microgram iya kukunika iinhlayiya ezinkulu ezingenakuncitshiswa ngesikhumba sakho. I-trade-off uyayijonga ifilimu emhlophe kwesikhumba sakho emva kwesicelo.
Enye inketho xa unomdla kukugwema iimveliso ze-titanium dioxide ngokupheleleyo, kuba le isithako sinxulumene neengxaki ezinokwenzeka. Kodwa ke khumbula ukuba ezininzi zezi ngxaki zivela ekungeniseni okanye ekutyeni i-titanium dioxide nanoparticles, kwaye kungekhona ekuthineni kwesikhumba.
I-sunscreen yemvelo, zombini i-micronized kwaye ayikho, ihluka kakhulu ngokuvumelana kwayo kwaye ivakale ekhumbeni. Ngoko, ukuba uphawu oluthile alukho ukuthanda kwakho, zama omnye uze ufumane lowo osebenza kuwe .
