In this laboratory-based study, waterless hand rub sanitizers available in the marketplaces at the time of commencing the study were selected based on the "99.9 bacterial reduction" or "antibacterial" labelling.

Results demonstrated variant antibacterial activities of 8 hand sanitizers out of 13 when tested on agar well diffusion method with zone of inhibition diameter ranges between ll-30mm. MBC assay showed bactericidal effectiveness of 4 hand sanitizers out of 13 with dissimilar time-kill between 10-50 seconds. In conclusion, water-based hand sanitizer (Dettol® foam hand wash) was experimentally the most effective product both on agar well diffusion method and time-kill test.
