benzophenone yog dab tsi?

Benzophenone yog siv dav hauv cov khoom siv hauv tsev xws li looj tsom iav dub, ntim khoom noj, ntxhua khaub ncaws thiab ntxuav cov khoom los tiv thaiv UV raug. Nws tuaj yeem paug cov dej haus thiab txav los ntawm cov ntim khoom noj mus rau cov khoom noj. Benzophenone yog siv nyob rau hauv ib co zaub mov ntim inks thiab tej zaum yuav tsiv mus nyob rau hauv cov zaub mov. Benzophenone tshwm sim nyob rau hauv tej yam khoom noj (xws li wine grapes thiab Muscat grapes) thiab ntxiv rau lwm tus raws li ib tug flavoring neeg sawv cev.
Hauv cov khoom siv tu tus kheej, benzophenone yog siv los ua cov tshuaj tsw qab lossis tiv thaiv cov khoom xws li xab npum los ntawm kev poob lawv cov ntxhiab thiab xim nyob rau hauv lub teeb ultraviolet. Benzophenone derivatives xws li BP2 thiab oxybenzone (BP3) yog siv rau hauv cov tshuaj pleev thaiv hnub. Oxybenzone yog siv los ua ultraviolet absorber thiab stabilizer, tshwj xeeb tshaj yog nyob rau hauv cov yas thiab cov tshuaj pleev thaiv hnub. Benzophenone thiab oxybenzone kuj tseem siv rau hauv cov ntsia thawv polish thiab di ncauj balm.
Cov pov thawj txuas benzophenones thiab cov khoom sib txawv rau cov kab mob endocrine yog sib xyaw, nrog cov kev tshawb fawb qhia tias cov benzophenones sib txawv muaj cov teebmeem endocrine sib txawv. Qee qhov kev tshawb fawb tau pom tias benzophenone muaj tsawg los tsis muaj kev ua estrogenic. Txawm li cas los xij, kev tshawb fawb ntawm benzophenone nyob rau hauv cov poj niam hluas nas tau xaus lus tias benzophenone tsis yog ib qho tshuaj estrogen los ntawm nws tus kheej, tab sis yuav dhau los ua tshuaj estrogen thaum nws metabolized los ntawm lub cev mus rau lwm yam tshuaj (piv txwv li, benzophenone metabolite p-hydroxybenzophenone yog ib qho tshuaj estrogen). Cov kev tshawb fawb hauv cov nas laus tau pom tias metabolized benzophenone tuaj yeem ua rau muaj kev ua estrogenic. Cov European Committee ntawm Endocrine cuam tshuam tau txiav txim siab tias tsis muaj pov thawj txaus tias benzophenone nws tus kheej yog ib qho cuam tshuam rau tib neeg endocrine.
Qee cov kev tshawb fawb tau pom tias benzophenone derivative oxybenzone tuaj yeem ua rau muaj zog antiandrogenic kev ua haujlwm hauv tib neeg lub mis mob qog noj ntshav kab MDA-kb2. Lwm cov kev tshawb fawb tau pom tias oxybenzone muaj cov tshuaj estrogenic, raws li tau hais los ntawm kev tshawb fawb ntawm cov tshuaj estrogen-sensitive MCF-7 kab mob qog noj ntshav mis, tab sis lwm cov kev tshawb fawb tau pom cov tshuaj estrogenic qis dua. Kev tshawb fawb txog kev ua estrogenic thiab kev ua me nyuam ntawm oxybenzone tau pom tias oxybenzone tuaj yeem hloov pauv qhov kawg ntawm cov ntses. Cov kev tshawb fawb hauv cov nas laus pom tias oxybenzone tsis cuam tshuam rau lub tsev menyuam. Txawm hais tias cov ntaub ntawv pov thawj ntawm oxybenzone lub peev xwm los ua cov tshuaj estrogen yog sib xyaw, nws tuaj yeem hloov mus rau lwm cov ntaub ntawv uas nthuav tawm cov tshuaj estrogen, xws li BP8 thiab 2,4,4 '-trihydroxybenzophenone (THB). BP2, BP8, thiab THB txhawb kev loj hlob (kev loj hlob thiab kev loj hlob) ntawm MCF-7 hlwb, uas yog siv los ntsuas cov tshuaj estrogen.
