Mouth washing
Dose:0.3%
Test method:add the 1.0ml bacteria solution (1×106~5 ×106cfu/ml) ,after30 second,Dilute,and count after anaerobic cultivation 72 hours
Sterilizing rate=(Average colony number in blank group-average colony number in experimental group) ÷ average colony number in blank group × 100%
Result:
sterilizing rate(30min)= 99.998302%
sterilizing rate(30S)=99.99786%
According to QB/T 2738-2012 ,sterilizing rate≥90 %,means it is acceptable in mouth washing
