Based on Health Technology Assessment Section Medical Development Division Ministry of Health Malaysia (008/2013), Sanitizer is an agent that reduces the number of bacterial contaminants to safe level as judged by public health requirements and registered by USEPA for public health uses
If your hands aren’t actually grimy, the best way to clean them is to use hand sanitizer, says James Scott, a microbiologist at the University of Toronto’s Dalla Lana School of Public Health. ‘A sanitizer cleans your hands much better than soap and water, it reduces the bacterial burden to a much greater extent and your hands tend to stay cleaner longer.
To use a hand sanitizer effectively
Make sure your hands are free of visible grime and dirt before applying the product.
Then, apply a palm-full of product and rub vigorously for 20 to 30 seconds, making sure to distribute the sanitizer between your fingers, under your nails and jewelry, on your wrists and on the backs of each hand. When your hands are dry, you’re good to go.
Never rinse your hands with water or wipe them with a towel after using a hand sanitizer. This will counteract the effectiveness of the product.
