Abstract
A topical sanitizing composition for reducing the concentration of non-enveloped viruses on the skin is provided. The topical sanitizing composition includes one or more pH adjusters, at least one carbomer, and at least about 50 wt. % of one or more C1-8 alcohols. The sanitizing composition with pH adjuster and carbomer is able to achieve at least a 3.0 log reduction in the concentration of the non-enveloped virus and in some cases passes the EN 14476 standard.
