Bleaching Powder

Bleaching powder is white to offwhite powder having calcium hypochlorite {(Ca(OCl)2} as the main active ingredient. It is produced by treating lime with chlorine gas. Stable below 0.5 % moisture contents. Produces chlorine odor or HOCl in case of high moisture contents and starts decomposing. Decomposes by absorption of CO2 from air. Decomposition by oxygen separation with low water contents which is accelerated in the presence of heavy metals Fe+3, Ni and Co etc. It catches fire on exposure to naked flame and high temperature. ature and dry place.

Shelf Life:  One year in airtight drums; 03 months in airtight bags, if stored at room temperature and dry place.
