Characterized los ntawm kev solubility thiab stability, cov khoom no yog ib tug npaum preservative. Ntawm 25 degree, nws muaj dej solubility txog 2.5 g / L, yog soluble hauv ethanol thiab propylene glycol, thiab muaj cov dej tsis zoo hauv cov roj. Nws yog ruaj khov nyob rau hauv acidic thiab nruab nrab tej yam kev mob, tab sis tej zaum yuav undergo hydrolysis thaum rhuab mus rau high kub.
Qhov Zoo Tshaj Plaws
Nws muaj qhov dav -spectrum antibacterial kev ua si, zoo suppressing kev loj hlob ntawm pwm, poov xab thiab tej yam kab mob.
Qhov zoo tshaj pH ntau rau nws cov tshuaj tua kab mob yog 4-7, uas yog raws li pH ntawm feem ntau cov tshuaj pleev ib ce, zaub mov thiab tshuaj.
Ntxiv mus, nws yog siv nyob rau hauv ib tug tsawg concentration ntawm 0.1% mus rau 0.3% nyob rau hauv cov khoom muaj feem xyuam, kom muaj kev ruaj ntseg thiab zoo preservation nyhuv.
