Uthathe isigqibo sokuba ukusebenzisa i-sunscreen yendalo lukhetho olufanelekileyo kuwe. Mhlawumbi uvakalelwa kukuba lukhetho olunempilo kuwe kunye nokusingqongileyo, okanye i-sunscreen enezithako ezisebenzayo zicaphukisa isikhumba sakho se-oh-so-sensitive.
Emva koko uva malunga "ne-nanoparticles" kwezinye izikrini zelanga zendalo, kunye nolwazi olothusayo kunye nolwazi oluphikisanayo malunga namasuntswana achaziweyo akunika ikhefu. Ngokunyanisekileyo, ngaba ukukhetha i-sunscreen yendalo kufuneka kube oku kudidayo?
Ngolwazi oluninzi olukhoyo, lunokubonakala lunzima. Ke, masinqumle ingxolo kwaye sijonge ngokungakhethiyo kwi-nanoparticles kwi-sunscreen, ukhuseleko lwazo, izizathu zokuba kutheni uya kuzifuna kwiscreen sakho selanga kwaye xa ungafuni.
Ziziphi iiNanoparticles?
Iinanoparticles ngamasuntswana amancinane ngokumangalisayo ento ethile. Iinanoparticles zingaphantsi kwe-100 nanometers ubukhulu. Ukunika imbono ethile, i-nanometer incinci ngamaxesha angama-1000 kunobunzima bomsonto omnye weenwele.
Ngelixa i-nanoparticles inokudalwa ngokwemvelo, njengamaconsi amancinci e-spray yolwandle ngokomzekelo, i-nanoparticles eninzi yenziwe kwilebhu. Kwi-sunscreen, i-nanoparticles echaphazelekayo yi-zinc oxide kunye ne-titanium dioxide. Ezi zithako ziqhekezwe zibe ziincinci ze-ultra-fine ngaphambi kokuba zongezwe kwi-sunscreen yakho.
I-Nanoparticles yaqala ukufumaneka kwi-sunscreens kwi-1980s, kodwa ayizange ibambe kude kube yi-1990s. Namhlanje, unokucinga ukuba i-sunscreen yakho yendalo kunye ne-zinc oxide kunye / okanye i-titanium dioxide ngamasuntswana angama-nano-ubungakanani ngaphandle kokuba kuchazwe ngenye indlela.
Amagama athi "nano" kunye "ne-micronized" ayafana. Ke, i-sunscreen ephethe "i-micronized zinc oxide" okanye "i-micronized titanium dioxide" ileyibhile iqulethe i-nanoparticles.
I-Nanoparticles ayifumaneki nje kwi-sunscreens. Uninzi lweemveliso zokhathalelo lwesikhumba kunye nezithambiso, njengeziseko, ishampoo, kunye nentlama yamazinyo, zihlala zinezithako ezincinci. Iinanoparticles zikwasetyenziswa kwi-electronics, amalaphu, iglasi enganyangekiyo, kunye nokunye.
I-Nanoparticles Gcina i-Sunscreens yeNdalo ukusuka ekushiyeni ifilimu emhlophe kwiLusu lakho
Xa ukhetha i-sunscreen yakho yendalo, unokhetho ezimbini; abo bane-nanoparticles kunye nabo bangenayo. Umahluko phakathi kwezi zimbini uya kubonakala eluswini lwakho.
Zombini i-titanium dioxide kunye ne-zinc oxide zivunyiwe yi-FDA njengezithako zendalo zokukhusela ilanga. Nganye inika ukhuseleko olubanzi lwe-UV, nangona i-titanium dioxide isebenza ngcono xa idityaniswe ne-zinc oxide okanye enye into eyenziweyo ye-sunscreen.
I-zinc oxide kunye ne-titanium dioxide zisebenza ngokubonisa imitha ye-UV kude nolusu, ikhusela ulusu elangeni. Kwaye zisebenza kakhulu.
Ngokwesiqhelo, ubungakanani be-nano, i-zinc oxide kunye ne-titanium dioxide zimhlophe kakhulu. Xa zifakwe kwi-sunscreen, ziya kushiya ifilimu emhlophe e-opaque ecacileyo kulo lonke ulusu. Cinga ngonogada abaqhelekileyo abamhlophe ngaphaya kwebhulorho yempumlo—ewe, yizinc oxide leyo.
Ngena nanoparticles. I-sunscreen eyenziwe nge-micronized zinc oxide kunye ne-titanium dioxide ikhuhla esikhumbeni ngcono kakhulu, kwaye ayiyi kushiya ngasemva inkangeleko ye-pasty. I-ultra-fine nanoparticles zenza ukuba i-sunscreen ingabonakali kodwa iyasebenza.
Uninzi olukhulu loPhando lufumana i-Nanoparticles kwi-Sunscreen ekhuselekileyo
Ukususela kwinto esiyaziyo ngoku, akubonakali ngathi i-nanoparticles ye-zinc oxide okanye i-titanium dioxide iyingozi nangayiphi na indlela. Nangona kunjalo, iziphumo zexesha elide lokusebenzisa i-micronized zinc oxide kunye ne-titanium dioxide, yinto engaqondakaliyo. Ngamanye amazwi, akukho bungqina bokuba ukusetyenziswa kwexesha elide kukhuselekile ngokupheleleyo, kodwa akukho bungqina bokuba kuyingozi.
Abanye baye bathandabuza ukukhuseleka kwala masuntswana e-micronized. Ngenxa yokuba zincinci, ziyakwazi ukufunxa ulusu kunye nomzimba. Ubungakanani bezinto ezifunxayo kunye nokuba zingene nzulu kangakanani kuxhomekeke kwindlela amasuntswana e-zinc oxide okanye i-titanium dioxide, kunye nendlela ahanjiswa ngayo.
Ukukhaba, kwenzeka ntoni emzimbeni wakho ukuba i-zinc oxide okanye i-titanium dioxide nano-particles ifunnyiwe? Ngelishwa, akukho mpendulo ecacileyo yaloo nto, nayo.
Kukho uqikelelo lokuba banokucinezela kwaye bonakalise iiseli zomzimba wethu, ukukhawulezisa ukuguga ngaphakathi nangaphandle. Kodwa uphando oluninzi kufuneka lwenziwe ukwazi ngokuqinisekileyo enye indlela okanye enye.
I-Titanium dioxide, xa ikwimo yayo engumgubo kwaye itsaliwe, ibonakaliswe ibangela umhlaza wemiphunga kwiimpuku zaselebhu. I-Micronized titanium dioxide ikwangena esikhumbeni nzulu ngakumbi kune-micronized zinc oxide, kwaye i-titanium dioxide ibonakaliswe ukuba idlula kwi-placenta kwaye ivale umqobo wegazi-ubuchopho.
Khumbula, nangona kunjalo, ukuba uninzi lolu lwazi luvela ekufakeni i-titanium dioxide (ekubeni ifumaneka kukutya okuninzi kunye neelekese ezisele zipakishwe). Ukususela kwizifundo ezininzi ze-micronized titanium dioxide kunye ne-zinc oxide esetyenzisiweyo, ngamanye amaxesha ezi zithako zifumaneka eluswini, kwaye nangona kunjalo zaziphantsi kakhulu.
Oko kuthetha ukuba nokuba usebenzisa i-sunscreen equkethe i-nanoparticles, ayinakukwazi ukugqithisela kuluhlu lokuqala lwesikhumba. Isixa esifunliweyo siyahluka kakhulu ngokuxhomekeke ekuqulunqweni kwe-sunscreen, kwaye uninzi lwalo aluyi kufunxa nzulu ukuba lukhona.
Ngolwazi esinalo ngoku, i-sunscreen equkethe i-nanoparticles ibonakala ikhuselekile kwaye isebenza kakhulu. Okungacacanga kangako yimpembelelo yexesha elide enokuba nayo imveliso kwimpilo yakho, ngakumbi ukuba usebenzisa imveliso yonke imihla. Kwakhona, akukho bungqina bokuba ukusetyenziswa kwexesha elide kwe-micronized zinc oxide okanye i-titanium dioxide kuyingozi, asazi nje ukuba yintoni umphumo onalo (ukuba ukhona) eluswini okanye emzimbeni wakho.
Ilizwi elivela kuWell
Okokuqala, khumbula ukuba ukunxiba i-sunscreen yonke imihla yenye yezona zinto zibalaseleyo onokuthi uzenze kwimpilo yexesha elide yolusu lwakho (kwaye yeyona ndlela ichasene nokuguga nayo). Ke, ndiyabulela kuwe ngokuthatha inyathelo ekukhuseleni ulusu lwakho!
Zininzi ii-sunscreens zendalo ezikhoyo, zombini iinketho ze-nano kunye nezingezizo ze-nano, ngokuqinisekileyo kukho imveliso ekhoyo kuwe. Ukusebenzisa i-sunscreen ene-micronized (i-AKA nano-particle) i-zinc oxide okanye i-titanium dioxide iya kukunika imveliso engaphantsi kwe-pasty kunye ne-rubs ngokupheleleyo.
Ukuba unenkxalabo malunga ne-nano-particles, ukusebenzisa i-sunscreen non-micronized kuya kukunika amaqhekeza amakhulu angenakukwazi ukuthatyathwa lusu lwakho. Ukurhweba kukuba uya kuqaphela ifilimu emhlophe eluswini lwakho emva kokufakwa kwesicelo.
Enye inketho ukuba unenkxalabo kukuphepha imveliso ye-titanium dioxide ye-micronized ngokupheleleyo, kuba esi sithako sisona sidityaniswe neengxaki zezempilo ezinokwenzeka. Khumbula, nangona kunjalo, ukuba uninzi lwezi ngxaki zibangelwa kukuphefumla okanye ukufunxa i-titanium dioxide nanoparticles, kwaye hayi ukufunxa ulusu.
I-sunscreen yendalo, zombini i-micronized kwaye ingekho, iyahluka kakhulu ehambelanayo kunye nokuvakalelwa kwesikhumba. Ke, ukuba enye ibhrendi ayikuthandi, zama enye de ufumane ekusebenzelayo.
