ABSTRACT:
Process for the stabilization of particles containing peroxygen compounds and bleaching compositions containing particles stabilized according to this process. The particles containing peroxygen compounds are kept in a fluidized bed. A coating agent which is insoluble in water and melts at low temperatures is introduced in the form of solid particles into the fluidized bed. The fluidized bed is kept at a temperature at least equal to the melting point of the coating agent.
