Unlike other sanitizers which only kill germs upon initial use, safeHands is designed to kill on contact and offers extended protection against bacteria and germs. The persistent “microbe killing power” of safeHands is attributed to its unique, patented, antimicrobial technology which uses Benzalkonium Chloride for its proven ability to kill a broad-spectrum of pathogens. Combining the effectiveness of BZK with additional proprietary ingredients that work synergistically to achieve of a comprehensive barrier, safeHands keeps hands moisturized and prevent dryness by working with the natural oils of the skin without sacrificing efficacy. This case of 4 x Unscented 128oz/1-Gallon refill jugs is ideal as an economical way to fill any foamer or sprayer bottle with the SafeHands formula. There is an option to include a foamer pump per jug. This is the only foamer pump for a gallon hand sanitizer on the market!
