    摘要: A stabilized sodium percarbonate particle includes a sodium percarbonate particle having at least one coating layer thereon, wherein the at least one coating layer includes (a) a silicate; (b) magnesium sulfate; and (c) an alkali metal salt selected from the group consisting of alkali metal carbonates, alkali metal bicarbonates and alkali metal sulfate. The present sodium percarbonate particle is good in solubility and is excellent in its formulation stability with detergent.
