A method for stabilizing particulate peroxycarboxylic acids, in particular imidoperoxycarboxylic acids, (such as, e.g., PAP), which are solid at an ambient temperature in a preferably aqueous dispersion containing surfactants. The dispersion is established in such a way that in the dispersed state a degradation of the peroxycarboxylic acids in the dispersion is prevented or at least reduced or retarded, or that the solubility of the peroxycarboxylic acids in the dispersion is diminished, in particular by minimizing the halide ion content, reducing the pH value to pH values <=7, minimizing the content of free or active surfactants, minimizing the content of non-ionic surfactants, adding complexers, adding catalases or adding a solvent with a low solubility capability for peroxycarboxylic acids etc.
