Definitions

  • the present invention relates to the use of ester peracids to improve surface wetting in the disinfection of surfaces and to synergistic antimicrobial combinations of ester peracids with other components.
  • peracid compounds such as e.g. Peracetic acid.
  • Peracid compounds are very effective biocides. Nevertheless, the smell of most peracids is perceived as annoying, especially when it is used in systems in which people are exposed to the smell. It was therefore worthwhile to find alternative disinfectants. Since disinfectants with an oxidative mechanism of action can usually kill germs within a short period of time, one would like to use them for surface disinfection.
  • the patent EP 765 309 relates to storage-stable, aqueous ester persic acid solutions and their use as disinfectants. According to the cited patent, these ester persic acid solutions have a reduced odor compared to the aliphatic d- to C 3 -peracids commonly used. It is thereby achieved that such ester persic acid solutions can be used in areas in which the use of peracids has hitherto been avoided due to the unpleasant smell.
  • the preferred surface-wetting auxiliaries often lead to formulations which are not very stable with peracid compounds.
  • additional aids can only be seen as additional ballast from an economic, ecological and toxicological point of view. Therefore, there was a need for oxidative agents that, when viewed in isolation, better wet surfaces.
  • the present invention relates to the use of formulations which contain at least one ester persic acid of the general formula
