A method for disinfecting a surface contaminated with microorganisms or suspected of being contaminated with microorganisms, the microorganism being one or more of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa , and Enterococcus hirae , including the step of contacting the surface with a disinfecting composition including: 0.1-10 wt. % of one or more N-acylated amino acids or N-acylated peptides, or a salt thereof, less than 0.1 wt. % of hydrogen peroxide, 0.1-20 wt. % of one or more non-ethoxylated anionic surfactants, 0.05-5 wt. % of a carboxylic acid, wherein the disinfecting composition has a pH in the range of 1-4.5 wherein the composition includes less than 5 wt. % of ethoxylated anionic surfactant. The invention also pertains to a composition suitable for use in the method according to the invention. The method and composition provide excellent biocidal activity over a broad range of organisms using low concentrations of organic acids. |
