Ib qho ntxiv ntawm kev siv triclosan hauv lub ntsej muag hmoov thiab blemish concealers ntawm qhov concentration no kuj tau pom tias muaj kev nyab xeeb, tab sis kev siv triclosan hauv lwm cov khoom tso tawm (xws li cov tshuaj pleev lub cev) thiab cov tshuaj ntxuav qhov ncauj tsis pom zoo rau cov neeg siv khoom vim qhov ua rau siab. raug.Kev nqus tau rau triclosan los ntawm cov khoom siv tshuaj tsuag (xws li deodorants) tsis raug ntsuas.
Triclosanyog non-ionic, nws tuaj yeem tsim nyob rau hauv cov pa dentifrices.Txawm li cas los xij, nws tsis khi rau qhov chaw ntawm qhov ncauj rau ntau tshaj li ob peb teev, thiab yog li ntawd tsis xa cov txheej txheem tiv thaiv cov quav hniav.Txhawm rau nce kev noj qab haus huv thiab khaws cia ntawm triclosan los ntawm qhov ncauj qhov chaw rau kev txhim kho cov plaque tswj thiab gingival noj qab haus huv, triclosan / polyvinylmethyl ether maleic acid copolymer thiab triclosan / zinc citrate thiab triclosan / calcium carbonate dentifrice yog siv.
triclosan siv li cas hauv kev kho mob thiab khoom siv kho mob?
Triclosantau siv zoo hauv kev kho mob kom tshem tawm cov kab mob me me xws li methicillin-resistant Staphylococcus aureus (MRSA), tshwj xeeb nrog kev pom zoo kom siv 2% triclosan da dej.Triclosan yog siv los ua cov tshuaj txhuam hniav, thiab nws tau siv dav hauv kev ntxuav tes thiab ua lub cev ntxuav kom tshem tawm MRSA los ntawm cov neeg nqa khoom ua ntej kev phais.
Triclosan yog siv nyob rau hauv ntau yam khoom siv kho mob, piv txwv li ureteral stents, phais sutures thiab tej zaum yuav raug txiav txim siab los tiv thaiv kab mob graft.Bojar et al tsis tau pom qhov sib txawv ntawm colonization ntawm triclosan-coated sutures thiab niaj zaus multifilament suture, txawm hais tias lawv txoj haujlwm cuam tshuam txog tsib kab mob thiab tsuas yog ua raws li kev txiav txim siab ntawm thaj tsam ntawm inhibition.
Hauv ureteral stents, triclosan tau pom tias inhibit qhov kev loj hlob ntawm cov kab mob uropathogens thiab txo qhov tshwm sim ntawm cov kab mob urinary-tract thiab, muaj peev xwm, catheter encrustation tsis ntev los no tau pom muaj kev sib koom ua ke ntawm triclosan thiab cov tshuaj tua kab mob tseem ceeb ntawm kev soj ntsuam cais tawm muaj xya hom kab mob uropathogenic, thiab lawv txhawb kev siv cov triclosan-eluting stent thaum tsim nyog, nrog rau cov qauv tshuaj tua kab mob hauv kev kho cov neeg mob nyuaj.
Hauv qee qhov kev txhim kho ntxiv, kev siv triclosan hauv urinary Foley catheter tau pom zoo txij li triclosan ntse inhibited kev loj hlob ntawm Proteus mirabilis thiab tswj encrustation thiab blockage ntawm lub catheter.Tsis ntev los no, Darouiche et al.Ua kom pom kev sib koom ua ke, dav-spectrum thiab ruaj khov kev ua haujlwm ntawm cov catheters coated nrog kev sib xyaw ntawm triclosan thiab DispersinB, ib qho tshuaj tiv thaiv biofilm uas inhibits thiab disperses biofilms.
triclosan siv li cas hauv lwm cov khoom siv?
Qhov dav-spectrum antimicrobial kev ua si ntawm triclosan tau ua rau nws koom ua ke nyob rau hauv ib qho kev nthuav dav ntawm cov khoom formulations npaj rau kev siv hauv tsev xws li cov xab npum ua kua, detergents, chopping boards, cov menyuam yaus cov khoom ua si, ntaub pua plag thiab cov thawv ntim khoom noj.Cov npe ncauj lus kom ntxaws ntawm cov khoom siv uas muaj triclosan yog muab los ntawm US Environmental Protection Agency (EPA) thiab los ntawm US NGOs "Environmental Working Group" thiab "Beyond Pesticides".
Cov khoom siv khaub ncaws ntau ntxiv tau kho nrog biocides.Triclosan yog ib qho ntawm cov khoom ua tiav rau kev tsim cov ntaub ntawv zoo li no .Cov ntaub ntawv tiav nrog triclosan raug kho nrog cov kab txuas txuas los muab cov khoom siv tiv thaiv kab mob.Raws li cov ntaub ntawv muaj, 17 cov khoom lag luam los ntawm Danish khw muag khoom tau txheeb xyuas cov ntsiab lus ntawm qee cov tshuaj tua kab mob uas tau xaiv: triclosan, dichlorophen, Kathon 893, hexachlorophen, triclocarban thiab Kathon CG.Tsib ntawm cov khoom tau pom tias muaj 0.0007% - 0.0195% triclosan .
Aiello et al nyob rau hauv thawj qhov kev tshuaj xyuas kev ntsuam xyuas cov txiaj ntsig ntawm xab npum uas muaj triclosan, soj ntsuam 27 cov kev tshawb fawb luam tawm thaum xyoo 1980 thiab 2006.
