Thaum koj xav txog titanium dioxide, koj yuav pom tias nws yog ib qho khoom siv hauv tshuaj pleev thaiv hnub lossis pleev xim. Txawm li cas los xij, qhov sib xyaw ua ke no kuj tseem siv rau hauv kev lag luam khoom noj, tshwj xeeb tshaj yog nyob rau hauv cov khoom xws li jelly thiabzom cov pos hniav. Tab sis dab tsi yog titanium dioxide? Koj yuav tsum txhawj xeeb txog qhov muaj titanium dioxide hauv koj cov zaub mov?
Titanium dioxide, tseem hu uaTiO 2, yog cov ntxhia ntuj uas feem ntau siv los ua cov tshuaj pleev xim dawb thiab xim ntxiv rau ntau yam khoom siv, suav nrog zaub mov. Hauv kev lag luam khoom noj khoom haus, titanium dioxide feem ntau yog siv los txhim kho cov tsos thiab kev ntxhib los mos ntawm qee yam khoom, xws li jelly thiab zom cov pos hniav. Nws muaj nuj nqis rau nws lub peev xwm los tsim cov xim dawb thiab du, creamy kev ntxhib los mos, ua rau nws yog ib qho kev xaiv nrov rau cov tuam txhab nrhiav kev txhim kho kev pom ntawm lawv cov khoom noj.
Txawm li cas los xij, kev sivtitanium dioxide hauv cov khoom nojtau ua rau muaj kev tsis sib haum xeeb thiab ua rau muaj kev txhawj xeeb ntawm cov neeg siv khoom thiab cov kws paub txog kev noj qab haus huv. Ib qho ntawm cov laj thawj tseem ceeb yog qhov muaj feem cuam tshuam txog kev noj qab haus huv ntawm kev noj titanium dioxide nanoparticles, uas yog cov khoom me me ntawm cov tshuaj sib txuas uas tuaj yeem nqus tau los ntawm lub cev.
Txawm hais tias kev nyab xeeb ntawm titanium dioxide hauv cov zaub mov tseem yog lub ntsiab lus ntawm kev sib cav, qee qhov kev tshawb fawb qhia tias kev siv titanium dioxide nanoparticles yuav muaj kev cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv. Piv txwv li, cov kev tshawb fawb tau pom tias cov nanoparticles no tuaj yeem ua rau mob plab hnyuv thiab cuam tshuam qhov sib npaug ntawm cov kab mob uas muaj txiaj ntsig, uas ua rau muaj teeb meem digestive thiab lwm yam teeb meem kev noj qab haus huv.
Hauv kev teb rau cov kev txhawj xeeb no, qee lub tebchaws tau siv cov kev txwv ntawm kev siv titanium dioxide hauv cov zaub mov. Piv txwv li, European Union tau faib cov titanium dioxide raws li qhov muaj peev xwm carcinogen thaum nqus tau, yog li txwv tsis pub nws siv los ua zaub mov ntxiv. Txawm li cas los xij, kev txwv tsis pub siv cov titanium dioxide hauv cov khoom noj, xws lijellythiab zom cov pos hniav.
Txawm hais tias muaj kev tsis sib haum xeeb nyob ib puag ncig titanium dioxide hauv cov zaub mov, nws tsim nyog sau cia tias qhov sib xyaw ua ke feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm US Food and Drug Administration (FDA) thaum siv raws li kev tsim khoom zoo. Cov neeg tsim khoom yuav tsum ua raws li cov lus qhia nruj heev txog kev siv titanium dioxide hauv cov khoom noj, suav nrog kev txwv ntawm cov nyiaj ntxiv rau cov khoom thiab qhov loj me ntawm cov khoom sib xyaw.
Yog li, qhov no txhais li cas rau cov neeg siv khoom? Thaum kev nyab xeeb ntawmtitanium dioxidenyob rau hauv cov zaub mov tseem tab tom kawm, nws yog ib qho tseem ceeb kom paub txog cov khoom koj noj thiab xaiv ntse txog koj cov khoom noj. Yog tias koj muaj kev txhawj xeeb txog qhov muaj titanium dioxide nyob rau hauv qee yam khoom noj, xav txog kev xaiv cov khoom uas tsis muaj cov tshuaj ntxiv no lossis nrog tus kws kho mob rau kev taw qhia.
Hauv cov ntsiab lus, titanium dioxide yog cov khoom muaj nyob rau hauv cov khoom noj xws li jellies thiab zom cov pos hniav, muaj nuj nqis rau nws lub peev xwm los txhim kho cov tsos thiab kev ntxhib los mos ntawm cov khoom noj no. Txawm li cas los xij, kev pheej hmoo ntawm kev noj qab haus huv cuam tshuam nrog kev noj titanium dioxide nanoparticles tau ua rau muaj kev txhawj xeeb ntawm cov neeg siv khoom thiab cov kws paub txog kev noj qab haus huv. Raws li kev tshawb fawb txuas ntxiv ntawm cov ncauj lus no, nws yog ib qho tseem ceeb rau cov neeg siv khoom kom paub meej thiab txiav txim siab paub txog cov khoom noj uas lawv haus. Txawm hais tias koj xaiv kom tsis txhob muaj cov khoom muaj titanium dioxide los yog tsis, kev nkag siab txog qhov muaj titanium dioxide hauv koj cov zaub mov yog thawj kauj ruam los tswj koj txoj kev noj qab haus huv thiab kev noj qab haus huv.
