Wasarudza kuti kushandisa mafuta ekudzivirira zuva echisikigo ndiyo sarudzo yakakunakira. Pamwe unofunga kuti ndiyo sarudzo ine hutano kwauri uye kune nharaunda, kana kuti mafuta ekudzivirira zuva ane zvinhu zvakagadzirwa zvinokanganisa ganda rako rinonyanya kunzwa.
Wobva wanzwa nezve "nanoparticles" mune mamwe ma "sunscreen agents" echisikigo, pamwe chete neruzivo runotyisa uye runopesana nezvezvinhu izvi zvinokupa mukana wekumira. Zvechokwadi, kusarudza ma "sunscreen agents" echisikigo kunofanira kunge kuchivhiringidza zvakadaro here?
Neruzivo rwakawanda rwuripo, zvinogona kuita sekunge zvinonetsa. Saka, ngationgororei ruzha rwacho tinyatsoongorora nanoparticles dziri musunscreen, kuchengetedzeka kwadzo, zvikonzero zvekuti nei uchizoda kuti dzive musunscreen yako uye kuti nguva yausingazodzidi ndeipi.
Chii chinonzi Nanoparticles?
Zvidimbu zvidiki zvikuru zvechinhu chakapihwa. Zvidimbu zvidiki zvidiki zvisingasviki 100 nanometers ukobvu. Kuti tipe maonero, nanometer idiki zvakapetwa ka1000 pane ukobvu hwebvudzi rimwe chete.
Kunyange zvazvo nanoparticles dzichigona kugadzirwa zvechisikigo, semadonhwe madiki emvura yegungwa semuenzaniso, nanoparticles zhinji dzinogadzirwa murabhoritari. Pazuva, nanoparticles dziri kutaurwa i zinc oxide ne titanium dioxide. Izvi zvinoshandiswa zvinopatsanurwa kuita zvidimbu zvidiki-diki zvisati zvawedzerwa pazuva rako.
Zvidimbu zveNanoparticles zvakatanga kuwanikwa muma sunscreens muma1980, asi hazvina kunyatsoonekwa kusvika kuma1990. Nhasi, unogona kufunga kuti sunscreen yako yechisikigo ine zinc oxide uye/kana titanium dioxide idiki-diki diki kunze kwekunge zvataurwa zvakasiyana.
Mashoko ekuti "nano" uye "micronized" akafanana. Saka, sunscreen ine "micronized zinc oxide" kana "micronized titanium dioxide" ine nanoparticles.
Zvidimbu zveNanoparticles hazvingowanikwi muzvinodzivirira zuva chete. Zvigadzirwa zvakawanda zvekuchengetedza ganda nezvizoro, zvakaita semafoundation, shampoos, uye toothpaste, zvinowanzova nezvinhu zvakaiswa micronized. Zvidimbu zveNanoparticles zvinoshandiswawo mumagetsi, machira, magirazi asingakwenyi, nezvimwewo.
Nanoparticles Inodzivirira Zvisimbiso zveZuva zvechisikigo Kuti Zvisasiye Firimu Chena paganda Rako
Pakusarudza mafuta ekudzivirira zuva, une sarudzo mbiri; ane nanoparticles neasina. Musiyano uripo pakati pezviviri izvi uchaonekwa paganda rako.
Zvese zviri zviviri titanium dioxide ne zinc oxide zvinotenderwa neFDA sezvinhu zvekuchengetedza zuva. Zvese izvi zvinopa dziviriro ye UV yakawanda, kunyange zvazvo titanium dioxide inoshanda zvakanyanya kana ikasanganiswa ne zinc oxide kana chimwe chinhu chekudzivirira zuva.
Zinc oxide netitanium dioxide zvinoshanda nekubvisa mwaranzi yeUV kubva paganda, zvichidzivirira ganda kubva kuzuva. Uye zvinoshanda zvikuru.
Muchimiro chazvo chakajairika, chisina kukura kwe nano, zinc oxide ne titanium dioxide zvichena chaizvo. Kana zvikaiswa mu sunscreen, zvinosiya ganda rakachena risingaonekwe. Funga nezve lifeguard ine chichena chakayambuka mhino—hongu, ndiyo zinc oxide.
Pinda muzvikamu zvidiki. Chinovhara zuva chakagadzirwa ne micronized zinc oxide ne titanium dioxide chinokwesha ganda zviri nani, uye hachizosiyi chitarisiko chakaita sechinotsvedza. Zvikamu zvidiki-diki zvinoita kuti chinodzivirira zuva chisanyanya kupenya asi chishande zvakafanana.
Ruzhinji rweVatsvagurudzi Rwakawana Kuti Nanoparticles Dziri MuSunscreen Safe
Kubva pane zvatinoziva iye zvino, hazviratidzike sekuti nanoparticles dzezinc oxide kana titanium dioxide dzine njodzi chero ipi zvayo. Zvisinei, mhedzisiro yenguva refu yekushandisa micronized zinc oxide uye titanium dioxide, inyaya isingazivikanwe. Nemamwe mashoko, hapana humbowo hwekuti kushandiswa kwenguva refu kwakachengeteka zvachose, asi hapana humbowo hwekuti kune njodzi futi.
Vamwe vakabvunza nezvekuchengetedzeka kwezvikamu izvi zvine micronized. Nekuti zvidiki kwazvo, zvinogona kunyudzwa neganda uye mumuviri. Kuti zvinonyudzwa zvakadii uye kuti zvinopinda zvakadzika sei zvinoenderana nekuti zvikamu zvezinc oxide kana titanium dioxide zvidiki sei, uye kuti zvinounzwa sei.
Kana muchida kukanda makumbo, chii chinoitika mumuviri wako kana zinc oxide kana titanium dioxide nano-particles zvikanyudzwa? Zvinosuwisa kuti hapana mhinduro yakajeka yeizvozvo zvakare.
Pane fungidziro yekuti zvinogona kushungurudza nekukuvadza masero emuviri wedu, zvichiita kuti kukwegura kuwedzere mukati nekunze. Asi tsvakiridzo yakawanda inofanira kuitwa kuti tizive zvakajeka nzira imwe neimwe.
Titanium dioxide, kana iri muchimiro cheupfu uye yakafemerwa, yakaratidzwa kuti inokonzera kenza yemapapu mumakonzo ekurabhoritari. Titanium dioxide ine micronized inopindawo muganda zvakadzika kupfuura micronized zinc oxide, uye titanium dioxide yakaratidzwa kuti inopfuura nepa placenta uye inovhara chipingamupinyi cheropa neuropi.
Asi yeuka kuti ruzivo urwu runobva mukunwa titanium dioxide (sezvo inowanikwa muzvikafu zvakawanda zvakatogadzirwa kare uye zvinotapira). Kubva muzvidzidzo zvakawanda zve micronized titanium dioxide uye zinc oxide zvinoshandiswa pamusoro, zvinhu izvi zvinowanikwa muganda nguva nenguva, uye kunyangwe zvakadaro zvaive zvisina kuwanda zvakanyanya.
Izvi zvinoreva kuti kunyangwe ukaisa sunscreen ine nanoparticles, dzinogona kusatopinda muganda. Huwandu hweganda hunosiyana zvichienderana nekugadzirwa kwesunscreen, uye yakawanda yacho haizopindi zvakanyanya kana ikatombopinda.
Neruzivo rwatiinarwo parizvino, mafuta ekudzivirira zuva ane nanoparticles anoita seakachengeteka uye anoshanda zvikuru. Hazvina kujeka kuti kushandiswa kwenguva refu kwechigadzirwa ichi kunogona kukanganisa hutano hwako, kunyanya kana uri kushandisa chigadzirwa ichi zuva nezuva. Zvakare, hapana humbowo hwekuti kushandisa kwenguva refu zinc oxide kana titanium dioxide kune njodzi, hatizivi kuti zvinokanganisa sei (kana zviripo) ganda rako kana muviri wako.
Shoko Rinobva kuVerywell
Chekutanga, yeuka kuti kupfeka mafuta ekudzivirira zuva zuva rega rega chimwe chezvinhu zvakanakisa zvaunogona kuita kuti ganda rako rirambe rakanaka kwenguva refu (uye ndiyo nzira yakanakisisa yekudzivirira kukwegura zvakare). Saka, tinokutendai nekushanda nesimba mukudzivirira ganda renyu!
Kune akawanda ma "sunscreen" echisikigo aripo, ese ari maviri nano neasiri nano, pane chigadzirwa chiripo chaunogona kushandisa. Kushandisa "sunscreen" ine micronized (AKA nano-particle) zinc oxide kana titanium dioxide kuchakupa chigadzirwa chisina pasty uye chinokwesha zvakakwana.
Kana uchinetseka nezve nano-particles, kushandisa sunscreen isina micronized kuchakupa zvidimbu zvakakura zvisinganyanyi kunyudzwa neganda rako. Chinhu chakanaka ndechekuti uchaona ganda rako rakaita ganda jena mushure mekuzora.
Imwe nzira kana uchinetseka ndeyekudzivisa zvachose zvigadzirwa zve titanium dioxide zvakaiswa mu micronized, sezvo chinhu ichi chiri icho chakabatanidzwa nematambudziko ehutano. Zvisinei, yeuka kuti matambudziko mazhinji aya aibva mukufema kana kunwa titanium dioxide nanoparticles, kwete kubva mukunwa ganda.
Zvizoro zvezuva zvechisikigo, zvose zvine micronized uye zvisina micronized, zvinosiyana zvakanyanya pakusimba kwazvo uye kunzwa kwazvo paganda. Saka, kana imwe mhando isingakufadze, edza imwe kusvika wawana inokushandira..
