Patent ID: 8883074

Claim:
A method for disinfecting a space, the space being a room or a chamber, by applying an aqueous disinfecting composition as a fine aerosol having a droplet size wherein 50% of the droplets have a diameter of at the most 100 μm to the space and leaving the space to air-dry, the aqueous composition comprising: a. hydrogen peroxide in a concentration of 1 to 10% (w/w); b. a cyclic carboxylic acid or salt thereof in a concentration of 0.01 to 2% (w/w); and c. a humectant in a concentration of 0.05% to 15% (w/w), the aqueous composition having a pH of 1 to 6, wherein the applying of the aqueous disinfecting composition produces at least a log 5 reduction in 2 minutes on Staphylococcus aureus in a controlled suspension test in accordance with EN 1276 and at least a log 5 reduction in 10 minutes on Aspergillus niger in a controlled suspension test in accordance with EN 1650.
