Abstract
A disinfectant hand wash includes triclosan and a reduced amount of surfactants in order to reduce skin irritation while maintaining improved activity against Gram negative and Gram positive organisms, including Serratia marcescens. The hand wash includes an effective amount of triclosan, preferrably 0.2-3.0% and a non-aqueous solvent. A mixture of hexylene glycol and isopropanol provide improved efficacy in killing skin-born microbes. The hand wash further includes 2-20% surfactant, preferrably at less than 10%. The hand wash further includes a chelating agent, a thickener, a buffering agent, and water.
