Abstract:
1. A method of disinfecting and providing residual kill at a surface, comprising: contacting said surface with a disinfectant solution, said disinfectant solution comprising from 0.0005 ppm to 50,000 ppm by weight of a colloidal transition metal or alloy having a particle size of 0.030 μm to 0.5 μm, an alcohol, a peroxygen compound, and water, wherein the peroxygen compound includes a peracid selected from the group consisting of peroxyformic acid, peroxyacetic acid, peroxyoxalic acid, peroxypropanoic acid, perlactic acid, peroxybutanoic acid, peroxypentanoic acid, peroxyhexanoic acid, peroxyadipic acid, peroxycitric, peroxybenzoic acid, and mixtures thereof, allowing evaporation of at least the alcohol and water from the disinfectant solution after contacting the surface leaving residual components, and maintaining the residual components on the surface such that the residual components of the disinfectant solution cause residual kill of bacterial, viral, or fungal organisms that subsequently contact the surface, wherein the disinfectant solution is substantially free of aldehydes, chlorine and bromine-containing compositions, iodophore-containing compositions, phenolic-containing compositions, and quaternary ammonium-containing compositions.
