The composition of white powdery material varies with different preparation conditions.

It is generally a hydrated double salt composed of calcium hypochlorite, calcium chloride and unreacted calcium hydroxide.

Its effective component is calcium hypochlorite.

Bleaching powder has strong oxidation, corrosiveness and irritation. It can decompose when it meets water, ethanol or inorganic acid.

When it meets water or inorganic acid, it can decompose into hypochlorous acid, which has strong oxidation, bleaching and sterilization properties.

Therefore, the bleaching effect of bleaching white powder is mainly based on the oxidation of hypochlorous acid.
