ABSTRACT:
This invention relates to a process of manufacturing granular sodium percarbonate and more particularly, to a process of a stable granular sodium percarbonate detergent composition having an excellent solution velocity when added to water, comprising the following steps: hydrogen peroxide solution is directly sprayed to unpurified anhydrous sodium carbonate to produce granular sodium percarbonate followed by the addition of a stabilizer having a new composition in a reactor or fluidized bed dryer, then recycling sodium percarbonate particles which are of nonuniform particle size back into the process for continuous manufacturing.
