Abstract: A method for preparing an aqueous solution or dispersion including peracetic acid, including the steps of adding a peroxygen donor and an acetyl donor to an aqueous solution or dispersion to prepare an aqueous solution or dispersion including the peroxygen donor and the acetyl donor, which generate peracetic acid and hydrogen peroxide over the course of time, and adding an organic acid to the aqueous solution or dispersion 10 min or later, such as 15 min or later after the preparation of the aqueous solution or dispersion including the peroxygen donor and the acetyl donor to buffer the pH of the aqueous solution or dispersion. The aqueous solution or dispersion obtained according to the method is suitable for use in an antimicrobial intervention to protect animals, preferably poultry, in particular chicken.

Abstract: The present invention is directed to improving the antibiotic efficacy of antibiotics and to an antimicrobial composition with increased antibiotic efficacy.

Abstract: The invention relates to a wound dressing or other wound contact medium containing an acetyl donor compound, and being free from peroxide compounds which is activatable by a means of applying hydrogen peroxide. The wound dressing or other wound contact medium is suitable for use in the prevention and/or treatment of wound infection in a patient comprising applying the wound dressing or other wound contact medium to a wound of the patient, and subjecting the wound dressing or other wound contact medium to a means of applying hydrogen peroxide so that the acetyl donor compound of the wound dressing or other wound contact medium is activated by the hydrogen peroxide to produce peracetic acid.

Abstract: An antimicrobial composition suitable for cleaning inanimate surfaces and human skin comprises two or more cationic biocides and two or more biocides which are slower acting than the cationic biocides, wherein each cationic biocide is independently either: (i) a quaternary ammonium compound at a concentration of at least 0.1% w/v; or (ii) a biguanide compound.
