The active ingredient in staSAFE, Argenius,™ a silver-zinc complex, does not evaporate like alcohol based sanitizers. It remains on your hands protecting you from germs for hours. We recommend using staSAFE immediately after washing to protect you between washes or whenever you feel the need to sanitize. Unlike alcohol based sanitizers, staSAFE does not strip your skin’s natural oils but instead partners with them, protecting your hands with Argenius and softening them with aloe vera. If you are currently sanitizing your hands with an alcohol based product you owe it to yourself to discover the wonder of staSAFE
