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.
