Puas yog phenoxyethanol ua mob rau daim tawv nqaij?

Dab tsi yogphenoxyethanol?
Phenoxyethanol yog glycol ether tsim los ntawm kev sib txuas cov phenolic pawg nrog ethanol, thiab nws zoo li cov roj los yog mucilage hauv nws cov kua hauv lub xeev.Nws yog ib qho tshuaj khaws cia hauv cov tshuaj pleev ib ce, thiab tuaj yeem pom nyob rau hauv txhua yam ntawm lub ntsej muag cream mus rau cov tshuaj pleev ib ce.
Phenoxyethanol ua tiav nws cov nyhuv preservative tsis yog los ntawm antioxidant tab sis los ntawm nws cov tshuaj tiv thaiv kab mob, uas inhibits thiab txawm tshem tawm cov koob tshuaj loj ntawm gram-zoo thiab tsis zoo microorganisms.Nws kuj muaj qhov cuam tshuam tseem ceeb rau ntau yam kab mob xws li E. coli thiab Staphylococcus aureus.
Puas yog phenoxyethanol ua mob rau daim tawv nqaij?
Phenoxyethanol tuaj yeem ua rau tuag taus thaum noj cov koob tshuaj loj.Txawm li cas los xij, kev siv tshuaj pleev xim rauphenoxyethanolntawm qhov concentrations tsawg dua 1.0% tseem nyob hauv qhov chaw nyab xeeb.
Peb tau tham yav dhau los seb ethanol puas metabolized rau acetaldehyde hauv ntau qhov ntawm daim tawv nqaij thiab seb nws puas tau nqus los ntawm daim tawv nqaij ntau.Ob qho no kuj tseem ceeb heev rau phenoxyethanol.Rau daim tawv nqaij nrog ib qho kev thaiv tsis zoo, phenoxyethanol yog ib qho ntawm cov glycol ethers ceev tshaj plaws degrading.Yog tias txoj kev metabolic ntawm phenoxyethanol zoo ib yam li ethanol, cov kauj ruam tom ntej yog tsim cov acetaldehyde tsis ruaj khov, ua raws li phenoxyacetic acid thiab lwm yam dawb radicals.
Tsis txhob txhawj!Thaum peb tham txog retinol ua ntej, peb kuj tau hais txog cov enzyme uas cuam tshuam nrog cov metabolism hauvphenoxyethanol, thiab tias cov txheej txheem hloov dua siab tshiab no tshwm sim nyob rau hauv stratum corneum.Yog li peb yuav tsum paub ntau npaum li cas phenoxyethanol yog absorbed transdermally.Nyob rau hauv ib txoj kev tshawb nrhiav uas tau kuaj qhov nqus ntawm cov dej-raws li sealant uas muaj phenoxyethanol thiab lwm yam tshuaj tiv thaiv kab mob, cov tawv nqaij npua (uas muaj qhov ze tshaj permeability rau tib neeg) yuav nqus 2% phenoxyethanol, uas tseem nce mus txog 1.4% tom qab 6 teev, thiab 11.3% tom qab 28 teev.
Cov kev tshawb fawb no qhia tias kev nqus thiab hloov pauv ntawmphenoxyethanolntawm qhov concentrations tsawg dua 1% yog tsis siab txaus los tsim cov tshuaj phem metabolites.Cov txiaj ntsig zoo sib xws kuj tau txais hauv cov kev tshawb fawb siv cov menyuam mos yug tshiab tsawg dua 27 lub lis piam.Txoj kev tshawb fawb tau hais tias, "Aqueousphenoxyethanoltsis ua rau muaj kev puas tsuaj rau daim tawv nqaij loj piv rau ethanol-based preservatives.Phenoxyethanol tau nkag mus rau hauv daim tawv nqaij ntawm cov menyuam mos yug tshiab, tab sis tsis tsim cov khoom oxidation phenoxyacetic acid ntau heev. "Qhov txiaj ntsig no kuj qhia tau tias phenoxyethanol muaj cov metabolism hauv ntau tshaj plaws hauv daim tawv nqaij thiab tsis ua rau muaj kev puas tsuaj loj. tuav nws, koj ntshai dab tsi?
Leej twg zoo dua, phenoxyethanol lossis cawv?
Txawm hais tias phenoxyethanol yog metabolized sai dua ethanol, qhov siab tshaj plaws txwv tsis pub siv tshuaj pleev ib ce yog qis dua 1%, yog li nws tsis yog qhov sib piv zoo.Txij li thaum lub stratum corneum tiv thaiv feem ntau ntawm cov molecules los ntawm absorbed, cov dawb radicals generated los ntawm ob yog ntau npaum li cas tsawg tshaj li cov generated los ntawm lawv tus kheej oxidation tshuaj txhua hnub!Ntxiv mus, vim hais tias phenoxyethanol muaj phenolic pawg nyob rau hauv daim ntawv ntawm cov roj, nws evaporates thiab dries qeeb dua.
Cov ntsiab lus
Phenoxyethanol yog ib qho tshuaj tiv thaiv uas siv hauv tshuaj pleev ib ce.Nws muaj kev nyab xeeb thiab siv tau, thiab tsuas yog thib ob rau parabens ntawm kev siv.Txawm hais tias kuv xav tias parabens kuj muaj kev nyab xeeb, yog tias koj tab tom nrhiav cov khoom tsis muaj parabens, phenoxyethanol yog qhov kev xaiv zoo!
