For cream form must i doing the antimicrob efficacy test
use filtration method and wash by sterilized water ,then inoculate the filter , i think it is enough
Filtration of cream is not possible with filter of 0,45micro.
Think you for your help
use diluent before filtration
Thanks but the cream is not an aqueous form
So is it necessary to do the test
dilute then pour 0.1 ml directly on agar plate
Before heat the container that contain cream at 45 at water bath and doing the test by pour plate method
Thanks i do it for property test but for effective antimicrobial we must inoculated the germs. So must I do it like syrup.
