Abstract (en)
[origin: EP0835926A2] The novel feature in production of coated bleach activator granules is that the granules are coated and simultaneously or subsequently tempered, the granules preferably having a melting point above 100 degrees C and the coating material a softening or melting point of 30-100 degrees C. The coating is preferably applied in a mixer or a fluidised bed device and the tempering is preferably effected at or near to the softening or melting point of the coating material.
