Abstract: 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.

Abstract: The invention pertains to an antimicrobial disinfecting composition including: a) 0.1-1 wt. % of each of at least one food allowed organic acid or a salt thereof; b) 0.1-1 wt. % of each of at least one amine oxide amphoteric surfactant, the composition having a total surfactant content which does not exceed 8 wt. %, wherein the total amount of betaine amphoteric surfactants in the composition is in the range of 0-75 wt. % of the total amount of amine oxide amphoteric surfactant. The composition is particularly suitable for use on skin or mucous membranes. On the one hand it shows good disinfecting properties, but on the other hand it does not lead to any use precautions or hazard or warning statements on the product label.
