Hand sanitizer foam features a benzalkonium chloride (BAK) formulation for use in environments where a nonalcoholic hand sanitizer is required. Safe, nonirritating formulation kills 99.99 percent of the most common germs that may cause illness without the use of soap and water. Controlled collapse technology allows the bottle to maintain its shape for longer to keep a more attractive appearance. Sanitary sealed design helps prevent contamination until use. Fragrance-free foam is compatible with vinyl, nitrile and latex gloves. Hand sanitizer is designed for use with PURELL LTX-12 dispensers (sold separately).
