CA 2407098

A method for antimicrobial treatment comprising applying to microbes a composition containing a diluting solvent (e.g., water), an antimicrobially-active solvent having a density different from the density of the diluting solvent, and an optional cosolvent, surfactant, or additional antimicrobial agent, wherein the amount of antimicrobially-active solvent or additional antimi-crobial agent is sufficiently high and the amount of cosolvent or surfactant is sufficiently low so that the composition will provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60 °C. Preferred methods of the invention employ compositions containing an additional antimicrobial agent such as peroxyacetic acid. Compositions for use in the method can be prepared as concentrates, and used full strength or in diluted form.

L'invention concerne un procédé de traitement antimicrobien qui consiste à appliquer aux microbes une composition contenant un solvant de dilution (par exemple de l'eau), un solvant à action antimicrobienne ayant une densité différente de celle du solvant de dilution, et éventuellement un co-solvant, un tensioactif ou un agent antimicrobien additionnel, la dose du solvant à action antimicrobienne ou de l'agent antimicrobien additionnel étant suffisamment élevée et celle du co-solvant ou du tensioactif suffisamment faible de façon que la composition puisse produire une réduction d'ordre 1-log dans la population de bactéries ou de spores de <i>Bacillus cereus </i>en 10 secondes à 60 DEG C. Dans des procédés préférés, les compositions contiennent un agent antimicrobien additionnel, par exemple de l'acide péroxyacétique. Les compositions utilisées dans le procédé peuvent être préparées en concentrés et utilisées en concentration intégrale ou sous forme diluée.
