For some students, certain commercial sanitizers dry out or irritate their skin. This one, however, features an emollient-rich formula that is gentle on skin, even with consistent daily use. It works by preventing skin breakdown, even on dry, cracked hands, while protecting and maintaining the skin barrier. It kills 99.9% of bacteria on contact and leaves behind persistent antimicrobial protection for up to 6 hours to further reduce exposure. It dries quickly without sticky residue and is free from fragrances and perfumes. Approved by CDC, AORN, and WHO. 16.9 oz.
