Iwe wafunga kuti kushandisa yakasikwa sunscreen ndiyo sarudzo yakakunakira iwe. Zvimwe iwe unonzwa kuti isarudzo ine hutano kwauri uye nenharaunda, kana sunscreen ine synthetic inoshanda zvinokanganisa ganda rako re-oh-so-sensitive.
Wobva wanzwa nezve "nanoparticles" mune mamwe masikirwo ezuva, pamwe nerumwe ruzivo runotyisa uye rwunopokana nezve zvidimbu zvataurwa zvinokupa kumbomira. Zvakaoma, kusarudza jira rezuva chairo kunofanirwa kuve kuvhiringika uku?
Neruzivo rwakawanda kunze uko, zvinogona kuita sekurema. Saka, ngatichekei neruzha uye titarise zvisina tsarukano pane nanoparticles mune sunscreen, kuchengetedzeka kwavo, zvikonzero nei uchivada mune yako sunscreen uye kana usingaite.
Chii chinonzi Nanoparticles?
Nanoparticles zvidimbu zvidiki zvinoshamisa zvechinhu chakapihwa. Nanoparticles ari pasi pe100 nanometers gobvu. Kupa mamwe maonero, nanometer idiki zvakapetwa ka1000 pane ukobvu hwetambo imwe yebvudzi.
Nepo nanoparticles inogona kugadzirwa zvakasikwa, senge minuscule madonhwe ekupfapfaidza yegungwa semuenzaniso, mazhinji nanoparticles anogadzirwa mulabhu. Kune sunscreen, nanoparticles ari mubvunzo zinc oxide uye titanium dioxide. Izvi zvinongedzo zvakaputswa kuita zvimedu-zvakanyanya kunaka zvisati zvawedzerwa kune yako sunscreen.
Nanoparticles yakatanga kuwanikwa mune sunscreens muma1980s, asi haina kunyatso kubata kusvika kuma1990s. Nhasi, unogona kutora sunscreen yako yakasikwa ine zinc oxide uye/kana titanium dioxide iri nano-sized particles kunze kwekunge zvataurwa neimwe nzira.
Mazwi ekuti "nano" uye "micronized" anofanana. Saka, sunscreen ine "micronized zinc oxide" kana "micronized titanium dioxide" label ine nanoparticles.
Nanoparticles haingowanikwi mune sunscreens. Zvizhinji zvekuchengetedza ganda uye zvigadzirwa zvekuzora, senge nheyo, shampoos, uye mushonga wemazino, kazhinji zvine micronized ingredients. Nanoparticles anoshandiswawo mumagetsi, machira, girazi risingapindike, nezvimwe.
Nanoparticles Chengetedza Natural Sunscreens Kubva Kusiya Firimu Rakachena paGanda Rako
Paunosarudza sunscreen yako chaiyo, une zvingasarudzwa zviviri; avo vane nanoparticles nevasina. Musiyano pakati pezviviri uchaonekwa paganda rako.
Ose titanium dioxide uye zinc oxide anotenderwa neFDA seyakasikwa sunscreening ingredients. Imwe neimwe inopa yakafara-spectrum UV dziviriro, kunyangwe titanium dioxide inoshanda zvakanyanya kana yasanganiswa ne zinc oxide kana imwe yekugadzira sunscreen ingredient.
Zinc oxide uye titanium dioxide inoshanda nekuratidzira UV mwaranzi kubva paganda, ichidzivirira ganda kubva kuzuva. Uye vanoshanda zvikuru.
Mune yavo yenguva dzose, isiri-nano saizi fomu, zinc oxide uye titanium dioxide ichena. Kana yakasanganiswa mumucheka wezuva, ivo vanosiya yakajeka opaque chena firimu paganda. Funga nezvemuchengetedzi ane chena akayambuka zambuko remhuno—ehe, iyo zinc oxide.
Pinda nanoparticles. Sunscreen yakagadzirwa ne micronized zinc oxide uye titanium dioxide yakakwesha muganda zviri nani, uye haizosiyi kuseri kwepasty. Iwo ekupedzisira-akanaka nanoparticles anoita kuti sunscreen isanyanya kujeka asi inonyatso shanda.
Iyo Yakakura Yakawanda Yekutsvaga Inowana Nanoparticles muSunscreen Yakachengeteka
Kubva pane zvatinoziva iye zvino, hazviratidzike kuti nanoparticles ye zinc oxide kana titanium dioxide inokuvadza nenzira ipi zvayo. Zvisinei, migumisiro yenguva refu yekushandisa micronized zinc oxide uye titanium dioxide, inongova chakavanzika. Mune mamwe mazwi, hapana humbowo hwekuti kushandiswa kwenguva refu kwakachengeteka zvachose, asi hapana humbowo kuti inokuvadza.
Vamwe vakapokana kuchengetedzwa kweaya ma micronized particles. Nemhaka yekuti idiki, inogona kutorwa neganda uye mumuviri. Yakawanda sei inotorwa uye kuti inopinda zvakadii zvinoenderana nekuti idiki zinc oxide kana titanium dioxide particles, uye kuti inounzwa sei.
Pakukandwa, chii chinoitika kumuviri wako kana zinc oxide kana titanium dioxide nano-particles ikanyura? Nehurombo, hapana mhinduro yakajeka kune iyo, kana.
Pane fungidziro yekuti vanogona kudzvanya nekukuvadza masero emuviri wedu, zvichiwedzera kukwegura mukati nekunze. Asi kutsvagisa kwakawanda kunoda kuitwa kuti uzive chokwadi neimwe nzira kana imwe.
Titanium dioxide, kana iri muhupfu uye nekufemerwa, yakaratidza kukonzera kenza yemapapu mumakonzo erabhoritari. Micronized titanium dioxide zvakare inopinda muganda zvakadzika zvakanyanya kupfuura micronized zinc oxide, uye titanium dioxide yakaratidzwa kuti inopfuura nepaplacenta uye ichivhara ropa-brain barriers.
Rangarira, zvakadaro, kuti yakawanda yeruzivo urwu rwunobva mukumedza titanium dioxide (sezvo ichiwanikwa mune zvakawanda zvekudya zvakarongwa kare uye masiwiti). Kubva pane dzakawanda zvidzidzo zve micronized titanium dioxide uye zinc oxide, pano neapo chete izvi zvinongedzo zvinowanikwa paganda, uye kunyangwe ipapo zvaive zvakaderera zvakanyanya.
Izvi zvinoreva kuti kunyange iwe ukashandisa sunscreen ine nanoparticles, inogona kusatombotora kupfuura yekutanga ganda. Huwandu hwakatorwa hunosiyana zvakanyanya zvichienderana nekuumbwa kwezuva, uye yakawanda yacho haitore zvakadzika kana zvachose.
Neruzivo rwatinarwo izvozvi, sunscreen ine nanoparticles inoita seyakachengeteka uye inoshanda zvakanyanya. Zvisina kujeka ndezvekushandiswa kwenguva refu kwechigadzirwa pahutano hwako, kunyanya kana uri kushandisa chigadzirwa zuva nezuva. Zvekare, hapana humbowo hwekuti kushandiswa kwenguva refu kwe micronized zinc oxide kana titanium dioxide kunokuvadza, isu hatingoziva kuti inobata sei (kana iripo) paganda rako kana muviri.
Izwi rinobva kuna Verywell
Kutanga, yeuka kuti kupfeka sunscreen zuva rega rega ndechimwe chezvinhu zvakanakisa zvaungaite kune hutano hurefu hweganda rako (uye ndiyo yakanakisa nzira yekurwisa kuchembera zvakare). Saka, kudos kwauri nekuita proactive mukudzivirira ganda rako!
Kune akawanda echisikigo sunscreens aripo, ese nano uye asiri-nano sarudzo, pane zvechokwadi chigadzirwa kunze uko kwauri. Kushandisa sunscreen ine micronized (AKA nano-particle) zinc oxide kana titanium dioxide inokupa chigadzirwa chisina kupfutika uye chinokwizwa zvakanyanya.
Kana iwe uine hanya nezve nano-particles, kushandisa isiri-micronized sunscreen inokupa iwe zvidimbu zvakakura zvisinganyanyi kubatwa neganda rako. Kutengeserana-kwekuti iwe uchaona firimu chena paganda rako mushure mekushandisa.
Imwe sarudzo kana iwe uine hanya ndeyekudzivisa micronized titanium dioxide zvigadzirwa zvachose, sezvo chinhu ichi chiri icho chakabatanidzwa kune zvinobvira heath matambudziko. Rangarira, zvakadaro, kuti mazhinji ematambudziko aya aive kubva mukufemesa kana kumedza titanium dioxide nanoparticles, uye kwete kubva mukutorwa kweganda.
Natural sunscreen, zvese micronized uye kwete, zvinosiyana zvakanyanya mukuenderana kwavo uye kunzwa paganda. Saka, kana imwe mhando isiri yekuda kwako, edza imwe kusvika wawana inokushandira.
