Purell is a Hand Sanitizer Brand that claims to kill 99.99% of common germs that in turn may cause illness. There is little physical or cognitive effort on the part of the consumer as Purell is sold at the checkout counter of many drugstores. Likewise, it engages with the authoritative aspect of influence in its claim about killing such a high percentage of germs…who wouldn’t want to have clean hands if that means one is healthier?
