Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for coating sodium percarbonate wherein a particle surface of sodium percarbonate is uniformly and efficiently coated with a coating material and energy load in a drying step is low. SOLUTION: Anhydrous sodium carbonate powder or anhydrous sodium sulfate powder with 5-200 μm average particle diameter is adsorbed on the particle surface of wet sodium percarbonate and subsequently the anhydrous compound is fixed to the particle surface of sodium percarbonate as a coating layer of the hydrate of the compound.
