Cov khoom khaws cia no nthuav tawm qhov sib txawv solubility thiab stability zoo. Tshwj xeeb, nws cov dej solubility yog nyob ib ncig ntawm 2.5 g / L ntawm 25 degree, nws tau yooj yim soluble hauv ethanol thiab propylene glycol, thiab me ntsis soluble hauv roj. Nws tseem nyob ruaj khov thaum nyob rau hauv acidic los yog nruab nrab tej yam kev mob, tab sis kub siab yuav ua rau nws hydrolysis
Qhov Zoo Tshaj Plaws
Ib qho ntawm nws cov txiaj ntsig tseem ceeb yog dav -spectrum antibacterial kev ua haujlwm, uas tuaj yeem cuam tshuam cov pwm, cov poov xab thiab qee hom kab mob.
Qhov zoo tshaj pH tus nqi rau nws cov tshuaj tua kab mob muaj nyob ntawm 4 txog 7, yoog raws li cov qauv tsim ntau.
Tsis tas li ntawd, nws yog siv nyob rau hauv ib tug tsawg concentration ntawm 0.1% -0.3% nyob rau hauv cov tshuaj pleev ib ce thiab tshuaj, kom ntseeg tau tias ob qho tib si preservation efficiency thiab kev nyab xeeb.
