Cov Lus Tseem Ceeb: Poly dimethyl diallyl ammonium chloride, PDMDAAC, Poly DADMAC, PDADMAC
Hauv lub ntiaj teb ntawm cov tshuaj pleev ib ce, txhua lub raj mis tshuaj pleev ib ce thiab txhua daim di ncauj muaj ntau yam zais cia ntawm kev tshawb fawb. Niaj hnub no, peb yuav qhia txog lub luag haujlwm tseem ceeb heev uas zoo li tsis paub meej tab sis tseem ceeb heev—Polydimethyl diallyl ammonium chloride.Tus "neeg ua siab loj uas tsis pom ntawm lub ntiaj teb tshuaj lom neeg" no tiv thaiv peb txoj kev zoo nkauj yam ntsiag to.
Thaum koj pleev xim rau sawv ntxov, koj puas tau xav tias vim li cas cov tshuaj tsuag plaub hau thiaj li tuaj yeem ua rau koj cov plaub hau zoo nkauj tam sim ntawd? Poly dimethyl diallyl ammonium chloride yog tus kws ua khawv koob tom qab txhua yam. Cov polymer cationic no ua haujlwm zoo li ntau lub hlau nplaum me me, lo rau cov plaub hau cuticle uas muaj roj tsis zoo. Tom qab cov dej hauv cov tshuaj tsuag qhuav, cov network uas nws tso tseg tso cai rau cov plaub hau kom nws cov duab zoo meej yam tsis muaj zog zoo li cov hlau hlau, tsis zoo li cov khoom siv pleev xim ib txwm muaj. Qhov zoo tshaj plaws, nws tuaj yeem kho cov plaub hau cuticles uas puas lawm, rov qab ci ntsa iab rau cov plaub hau thaum teeb tsa nws.
Thaum koj co lub raj mis tshuaj pleev, nws cov qauv du thiab mos yog ua tsaug rau lub khawv koob emulsifying ntawm P.DADMACHauv cov tshuaj pleev ib ce, nws siv cov kev sib cuam tshuam electrostatic los khi cov roj thiab cov dej kom nruj, tiv thaiv kev sib cais. Qhov "kev sib koom ua ke ntawm cov tshuaj lom neeg" no kav ntev dua li cov tshuaj emulsifiers, ua kom cov serum tseem nyob txawm tias los ntawm thawj tee mus rau qhov kawg. Cov ntaub ntawv hauv chav kuaj qhia tau hais tias cov tshuaj pleev ib ce uas muaj ntxivPDADMACmuaj kev ruaj khov zoo dua 40%, yog vim li cas cov khoom siv saib xyuas tawv nqaij zoo siab nyiam nws.
PDADMACHauv cov di ncauj pleev di ncauj muaj ob qho kev nyiam. Ua ib qho khoom sib txuas, nws ua kom cov xim sib npaug, tiv thaiv cov qhov tsis zoo thaum siv; ua tus neeg sawv cev ua zaj duab xis, nws tsim cov zaj duab xis ua pa tau rau cov xim ntev. Qhov xav tsis thoob ntxiv, nws cov khoom mos mos ua rau nws yog qhov kev xaiv zoo rau cov menyuam yaus pleev xim, nrog rau cov cai lij choj EU kom paub meej tias nws tsis ua xua.
Cov kws tshawb fawb tab tom tshawb nrhiav lwm txoj hauv kev rauPDADMAC: txhim kho qhov ruaj khov ntawm cov tshuaj nqus UV hauv cov tshuaj pleev thaiv hnub thiab txhim kho qhov nkag mus ntawm cov khoom xyaw nquag hauv cov ntaub npog ntsej muag. Kev tshawb pom tsis ntev los no los ntawm lub chaw kuaj mob Kaus Lim Qab Teb qhia tiasPoly DADMACntawm qhov hnyav molecular tshwj xeeb tuaj yeem txhawb nqa collagen synthesis, tej zaum yuav tshaj tawm txog kev tshawb pom tshiab hauv kev tiv thaiv kev laus.
Lub Koom Haum Thoob Ntiaj Teb Txog Cov Khoom Xyaw Rau Tshuaj Pleev Xim (INCI) muaj cov cai nruj heev uas tswj hwm kev siv cov khoom xyaw pleev xim.Poly DADMACkom ntseeg tau tias muaj kev sib npaug ntawm kev nyab xeeb thiab kev ua tau zoo. Nrog rau cov neeg siv khoom ntau zuj zus muab qhov tseem ceeb rau "kev huv si," kev tshawb fawb thiab kev txhim kho ntawm cov khoom siv bio-basedPoly DADMACtab tom nrawm dua, thiab peb yuav pom tus neeg saib xyuas kev zoo nkauj uas tau los ntawm cov nroj tsuag yav tom ntej.
Txij ntawm cov plaub hau mus rau daim di ncauj, tom qab lub npe uas ua rau neeg xav tsis thoobPoly DADMACyog lub tswv yim ntawm ntau tus kws ua haujlwm pleev kom zoo nkauj. Nws ua rau peb nco qab tias cov thev naus laus zis zoo nkauj tiag tiag feem ntau zais rau hauv lub ntiaj teb molecular uas peb tsis pom. Lub sijhawm tom ntej koj siv cov tshuaj pleev kom zoo nkauj, xav txog seb cov neeg saib xyuas uas peb tsis pom no maj mam hloov kho koj qhov kev zoo nkauj li cas.
