Thaum cov koom haum tswj hwm nruj dua cov kev txwv rau cov tshuaj preservatives ib txwm muaj thiab cov neeg siv khoom xav tau cov npe khoom xyaw uas pom tseeb thiab "huv si", cov neeg tsim cov tshuaj pleev ib ce tab tom ntsib teeb meem loj heev. Kev hloov pauv ntawm cov parabens thiab phenoxyethanol uas muaj kev sib cav sib ceg tau ua rau kev tshawb nrhiav lwm txoj hauv kev uas muaj ntau yam thiab muaj kev nyab xeeb.
Nkag mus4′-HydroxyacetophenoneChiv thawj pom muaj nyob rau hauv cov qia thiab nplooj ntawm alpine cloudberry, cov tshuaj no zoo ib yam li ntuj tsim tab tom hloov pauv sai sai los ntawm cov khoom ntxiv me me mus rau cov khoom xyaw tseem ceeb hauv cov tshuaj pleev ib ce niaj hnub no. Tab sis dhau ntawm daim ntawv lo rau kev zoo nkauj huv si, vim li cas cov neeg tsim khoom thiab cov thawj coj kev yuav khoom thiaj li hloov lawv cov saw hlau mus rau cov tshuaj tshwj xeeb no?
Nov yog kev kawm tob txog cov txiaj ntsig ntawm daim ntawv thov thiab cov khoom siv ntawm 4′-Hydroxyacetophenone.
I. Dhau Qhov Kev Tiv Thaiv: Qhov Ntug Siv Tau Ntau Yam
Tsis zoo li cov khoom ntxiv uas muaj ib txoj haujlwm xwb, 4′-Hydroxyacetophenone muaj ntau txoj hauv kev rau kev siv ntau yam hauv cov tshuaj pleev ib ce, uas yog qhov tsav nws txoj kev siv rau hauv cov kab kho mob tawv nqaij thiab cov kab saib xyuas menyuam yaus.
1. Tus Tshuaj Tiv Thaiv Zoo Tshaj Plaws
Los ntawm nws tus kheej,4′-Hydroxyacetophenonetsis yog ib yam tshuaj preservative uas siv dav dav. Txawm li cas los xij, nws qhov txiaj ntsig tiag tiag yog nyob rau hauv nws cov txiaj ntsig synergistic. Thaum ua ke nrog diols (xws li 1,2-Hexanediol lossis Caprylyl Glycol), 4'-Hydroxyacetophenone txo cov tshuaj preservatives uas xav tau hauv ib daim mis. Qhov no txo qhov kev pheej hmoo ntawm kev khaus tawv nqaij thaum tswj kev tiv thaiv kab mob.
2. Cov khoom tiv thaiv kab mob thiab soothing
Hauv kev siv rau kev saib xyuas tawv nqaij thiab kev siv tshuaj pleev thaiv hnub, 4'-Hydroxyacetophenone ua haujlwm ua tus tiv thaiv Cox-2. Qhov no txhais tau tias 4'-Hydroxyacetophenone pab ua kom cov tawv nqaij mos thiab tiv thaiv cov dawb radicals uas tshwm sim los ntawm kev raug UV, ntxiv rau qhov kev thov "ua haujlwm" thib ob rau cov khoom tiv thaiv kev laus thiab cov tshuaj pleev thaiv hnub.
3. Kev Ruaj Ntseg Siab Tshaj Plaws
Ib qho mob taub hau rau cov neeg tsim cov tshuaj yog qhov ua rau cov khoom xyaw puas tsuaj. 4′-Hydroxyacetophenone tseem ruaj khov heev thoob plaws ntau yam pH (feem ntau yog pH 3-9) thiab tuaj yeem tiv taus kev ua haujlwm kub siab (txog li 90 ° C). Qhov kev ruaj khov thermal no ua kom nws tsis tawg thaum lub sijhawm emulsification ntawm cov tshuaj pleev lossis tshuaj pleev.
II. Kev Tshawb Fawb Txog Cov Khoom Siv Los Ntawm Sab Nraud: Cov Khoom Siv Raw
Txawm hais tias cov txiaj ntsig ntawm daim ntawv thov yog qhov tseeb, cov neeg yuav khoom yuav tsum taug kev hauv kev lag luam sab saud uas hloov pauv tas li. Kev tsim cov khoom lag luam ntawm 4′-Hydroxyacetophenone vam khom ntau rau phenol thiab acetic anhydride lossis lwm yam khoom siv petrochemical.
Yog li ntawd, tus nqi ntawm4′-Hydroxyacetophenonemuaj feem cuam tshuam nrog cov roj av thoob ntiaj teb thiab cov nqi phenol. Kev kub ntxhov tsis ntev los no ntawm thaj chaw thiab kev hloov pauv ntawm cov nqi zog tau ua rau muaj kev hloov pauv hauv qhov kev lag luam no. Txawm li cas los xij, cov chaw tsim khoom ua ntej - tshwj xeeb tshaj yog cov uas muaj cov saw hlau sib koom ua ke - tab tom nqis peev rau hauv cov kev tsim cov tshuaj catalytic ntsuab dua. Qhov no tsis yog tsuas yog txhim kho cov txiaj ntsig xwb tab sis kuj txo qhov cuam tshuam ntawm ib puag ncig, ua kom cov txheej txheem tsim khoom sib haum nrog lub tswv yim "kev zoo nkauj huv si" uas cov khoom kawg txhawb nqa.
III. Txoj Kev Npaj Yuav Khoom: Tsis Txhob Ua Qhov "Kev Ntxeev Siab Zoo"
Thaum muaj neeg xav tau ntau ntxiv, kev ua lag luam tau pom muaj cov neeg muab khoom ntau zuj zus. Rau cov pab pawg yuav khoom, kev kho txhua yam 4′-Hydroxyacetophenone zoo ib yam yog qhov yuam kev kim heev.
Qhov sib txawv tseem ceeb yog qhov huv thiab tswj tau ntxhiab tsw. Cov khoom siv hauv kev lag luam tej zaum yuav muaj cov khoom tsis huv me ntsis uas ua rau muaj ntxhiab tsw phenolic uas ua rau neeg tsis nyiam - qhov tsis zoo rau cov tshuaj pleev ib ce zoo tshaj plaws uas tsis muaj ntxhiab tsw. Cov neeg yuav khoom yuav tsum xub muab cov neeg muag khoom uas siv cov txheej txheem crystallization thiab purification kom paub tseeb tias cov khoom lag luam hauv tshuaj lossis cov khoom huv heev (≥99.0%) nrog cov qauv tsis muaj ntxhiab.
Kev cia siab rau cov lus qhia nruj, cov hlau hnyav txwv, thiab kev thov cov ntaub ntawv pov thawj ntawm kev tshuaj xyuas kom ntxaws yog qhov tsis sib haum xeeb rau kev txo qis qhov ua tsis tiav ntawm cov qauv hauv qab.
IV. Txoj Kev Mus Tom Ntej
Cov khoom siv rau 4′-Hydroxyacetophenone tsis yog tsuas yog loj hlob xwb; nws tab tom loj hlob. Thaum kev lag luam saib xyuas tus kheej tshem tawm cov tshuaj preservatives qub, qhov kev vam khom rau cov tshuaj no yuav tsuas yog nce ntxiv. Cov neeg yuav khoom uas xauv cov kev xa khoom txhim khu kev qha, huv si tam sim no yuav tsis tsuas yog tiv thaiv lawv cov npoo ntawm cov khoom siv raw xwb tab sis kuj tseem yuav txhawb nqa lawv cov pab pawg R & D kom tsim kho tshiab hauv qhov chaw huv si.
V. Cov Lus Nug Feem Ntau (FAQ)
1. Lub luag haujlwm tseem ceeb ntawm yog dab tsi?4′-Hydroxyacetophenonehauv cov tshuaj pleev ib ce?
