US FDA tau tshaj tawm yuav tsum tau kuaj asbestos rau cov tshuaj pleev ib ce uas muaj talc hmoov

Thaum Lub Kaum Ob Hlis 26, 2024, US Food and Drug Administration (FDA) tau tshaj tawm cov lus pom zoo tseem ceeb uas xav kom cov tuam txhab tsim tshuaj pleev ib ce ua qhov yuav tsum tau kuaj asbestos ntawm talc uas muaj cov khoom raws li cov kev cai ntawm 2022 Cosmetic Regulatory Modernization Act (MoCRA). Cov lus pom zoo no yuav muaj kev cuam tshuam loj heev rau kev lag luam tshuaj pleev ib ce, tshwj xeeb tshaj yog nyob rau hauv qib tshuaj pleev ib ce talcum hmoov ua lag luam.

FDA txoj kev tshawb nrhiav pom feem ntau suav nrog ob hom: polarized light microscopy (PLM): hom no tuaj yeem txheeb xyuas ntau tus qauv thiab txheeb xyuas cov asbestos los ntawm kev soj ntsuam cov khoom siv kho qhov muag (xws li xim, ntau xim, refractive index, birefringence, thiab lwm yam. ) thiab particle morphology. Transmission Electron Microscopy/Energy Dispersive Spectroscopy/Selective Electron Diffraction (TEM/EDS/SAED): Txoj kev no tuaj yeem kuaj xyuas cov fibers me me thiab txheeb xyuas cov asbestos los ntawm kev tshuaj xyuas cov khoom muaj pes tsawg leeg, siv lead ua qauv, thiab particle morphology.

FDA tau hais tias kev sib koom ua ke ob txoj hauv kev no tuaj yeem ua kom pom cov asbestos ntau tshaj plaws. Txawm hais tias PLM muaj qhov loj me me, nws tuaj yeem txheeb xyuas ntau tus qauv; Thiab TEM / EDS / SAED tuaj yeem ntes cov fibers me me. Ob txoj hauv kev ntxiv rau ib leeg, txhim kho qhov raug thiab ua tiav ntawm kev tshawb pom.

Lub tswv yim ntawm cov txheej txheem thoob ntiaj teb zoo sib xws raws li cov qauv thoob ntiaj teb. Cov European Union, Canada, thiab Nyiv tau tsim cov kev cai nruj zoo sib xws los xyuas kom meej tias cov khoom talc tsis muaj cov pa phem asbestos. Cov txheej txheem microscopic xws li PLM thiab TEM tau siv dav thoob ntiaj teb kom pom tseeb asbestos. Qhov kev sib koom ua ke no tsis yog tsuas yog pab tiv thaiv cov neeg siv khoom noj qab haus huv xwb, tab sis kuj txhawb kev lag luam thoob ntiaj teb thiab ua kom cov neeg siv khoom muaj kev ntseeg siab rau kev nyab xeeb ntawm cov khoom lag luam talc thoob ntiaj teb.

FDA cov lus pom zoo tau hais meej tias yog tias cov tshuaj asbestos raug kuaj pom hauv cov tshuaj pleev ib ce lossis talc siv hauv cov tshuaj pleev ib ce, cov khoom yuav raug suav tias yog neeg deev thiab ua txhaum cai ntawm Tsoom Fwv Teb Chaws Khoom Noj, Tshuaj, thiab Tshuaj pleev ib ce. Txoj cai no muab lub hauv paus meej meej rau tub ceev xwm.

Lub hom phiaj tseem ceeb ntawm qhov kev thov no yog txhawm rau txo qhov kev pheej hmoo ntawm cov neeg siv khoom raug rau asbestos thiab tiv thaiv cov kab mob cuam tshuam. Nyob rau tib lub sijhawm, nws tseem yuav pab cov tuam txhab lag luam txo qhov zaus ntawm cov khoom rov qab thiab txo cov kev pheej hmoo ua haujlwm.

Tsis tas li ntawd, qhov kev pom zoo no ua rau qee qhov khoob hauv MoCRA cov lus qhia, tshwj xeeb tshaj yog hais txog kev nkag siab tsis txaus ntawm cov qauv ntsuas kev nyab xeeb los ntawm cov tuam txhab me thiab nruab nrab. Tam sim no FDA tau hais meej meej txog cov kev sim rau asbestos hauv talc, muab kev taw qhia meej rau kev lag luam.

FDA tau qhib lub sijhawm tshuaj xyuas pej xeem rau pej xeem kev koom tes thiab cov kauj ruam tom ntej, nrog rau lub sijhawm kawg ntawm Lub Peb Hlis 27, 2025. Qhov no muab lub sijhawm rau kev lag luam thiab cov pej xeem koom nrog cov txheej txheem tswj hwm. Yog tias thaum kawg dhau, txoj cai tshiab no yuav txhim kho kev nyab xeeb ntawm talc uas muaj cov tshuaj pleev ib ce thiab muab kev tiv thaiv zoo rau cov neeg siv khoom noj qab haus huv.

FDA cov lus pom zoo qhia txog kev tswj hwm cov neeg saib xyuas kev nyab xeeb ntawm cov tshuaj pleev ib ce, tshwj xeeb tshaj yog nyob rau hauv kev tshawb pom ntawm asbestos, uas paub txog carcinogen. Raws li FDA cov lus pom zoo tshiab, Bureau Veritas pom zoo tias cov tuam txhab tshuaj pleev ib ce pib ntsuas thiab hloov kho lawv cov txheej txheem tswj kom zoo thaum ntxov, tshwj xeeb tshaj yog rau cov khoom muaj talc. Cov tuam txhab lag luam ntsig txog yuav tsum nrhiav kev pab raws sij hawm los ntawm cov koom haum kuaj thib peb, cob qhia cov neeg ua haujlwm, thiab tsim kom muaj kev tswj xyuas cov saw hlau kom ua raws li cov kev cai tshiab, tswj hwm lub koob npe nrov, thiab cov neeg siv khoom ntseeg siab.

BTF Testing Lab, peb lub tuam txhab muaj electromagnetic compatibility laboratories, kev ruaj ntseg cov cai Laboratory, wireless xov tooj cua zaus Laboratory, roj teeb Laboratory, chemical Laboratory, SAR Laboratory, HAC Laboratory, thiab lwm yam. Peb tau txais kev tsim nyog thiab kev tso cai xws li CMA, CNAS, CPSC, VCCI, thiab lwm yam. Peb lub tuam txhab muaj kev paub dhau los thiab kev ua haujlwm engineering pab pawg, uas tuaj yeem pab cov lag luam daws qhov teeb meem. Yog tias koj muaj cov kev xav tau kev ntsuam xyuas thiab ntawv pov thawj, koj tuaj yeem tiv tauj peb cov neeg ua haujlwm Testing kom tau txais cov ncauj lus kom ntxaws nqe lus thiab cov ntaub ntawv voj voog!
