Sterizar is an Alcohol Free Hand Foaming Sanitiser formulated to kill bacteria in seconds. The product gives an immediate fresh and clean feel to the skin and it remains effective for at least 6 hours after application. There is no need to rinse this product and it is kind to your hands. Why Choose Alcohol Free? In addition to being highly flammable, alcohol-based hand sanitizers have been banned from many public school districts in the country, as they pose a significant danger to children who might accidentally or intentionally ingest the product. To put things in perspective, light beer is “6 Proof”; wine is “24 proof”; vodka is “80 Proof”; a number of alcohol based products are “125 Proof”! The risk of alcohol poisoning is quite real, and it is a danger to small children.
