ABSTRACT:
Particles of a fluidizable substance are coated with a complete and continuous coating by a process wherein a non-aqueous solution of a coating substance is sprayed from a nozzle downwardly on a fluidized bed of the particles to be coated, the nozzle height being adjusted so that the liquid droplets of coating material would just cover the cross-sectional area of the upper surface of the bed, if sprayed on the unexpanded bed. When the aforementioned coating is a fatty acid having 12-20 carbon atoms applied to particles of a chlorine-releasing agent, and when a second coating is applied by treatment with a solution of a fixed alkali hydroxide, i.e., sodium, potassium, or calcium hydroxide, an effective, completely encapsulated, non-pinholing bleach product is obtained.
