Stabilization of Sodium Percarbonate

摘要

Sodium percarbonate has been shown to be an effective oxygenbased bleaching agent that neither damages fabric nor causes yellowing. Unlike sodium perborate, sodium percarbonate does not require high temperatures to be effective. Percarbonate, however, has poor storage stability compared to sodium perborate. Small amounts of moisture cause decomposition, which can be accelerated by low levels of iron, copper, manganese, cobalt, and other heavy metal ions. Synthetic zeolite also strongly catalyzes the decomposition of sodium percarbonate.
