Abstract
The invention provides a skin disinfectant for treating skin with eczema, preventing bacterial proliferation, and removing biofilm. Compositions of the invention include hypochlorous acid, acetic acid, water, and one or more additives or excipients. The formulation process removes metal ions, reduces ionic strength, controls pH, and reduces exposure to air, thus improving stability and lengthening shelf-life.
