Additional information
Pure peracetic acid is not available because it is explosive. For this reason it is technically not possible to perform an experimental study according to the guidelines. However, peracetic solutions are clear, colourless with a stinging, vinegar-like odour.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
