Daim ntawv thov
Ethylparaben feem ntau yog siv los ua tshuaj tua kab mob hauv tshuaj pleev ib ce, zaub mov thiab tshuaj. Nws kuj tseem siv tau los ua cov khoom noj khoom haus thiab tshuaj tua kab mob rau cov kab mob.
Ethylparaben yog ib qho tshuaj preservative uas yog siv rau hauv kev tsim cov tshuaj pleev ib ce thiab cov khoom tu tus kheej txhawm rau txhawm rau txuas lub txee- lub neej los ntawm kev tiv thaiv kab mob microbial. Nyob rau hauv feem ntau formulations, parabens yog siv nyob rau hauv tsawg heev theem ntawm 0.01 mus rau 0.3%.
Ethylparaben, ib qho tshiab sorbent rau cov khoom-theem extraction, tau siv los kawm txog nws cov khoom khaws cia. Nws muaj cov txiaj ntsig zoo ntawm kev rho tawm ntawm cov tebchaw kuaj vim muaj kev cuam tshuam electrostatic, kev sib cuam tshuam hydrophobic thiab hydrogen bonding.
