Measured properties

Appearance: Obtained by saturating calcium hydroxide (slaked lime) with chlorine. · Calcium hypochlorite appears as a white granular solid (or tablets compressed from the granules) with an odor of chlorine. Toxic, irritating to the skin. Noncombustible, but will accelerate the burning of combustible materials. Prolonged exposure to fire or heat may result in the vigorous decomposition of the material and rupture of the container. Diluted samples may undergo reactions as described
Odour: Strong chlorine odor
Boiling point: Decomposes at 100 °C
Melting point: 100 °C
Solubility: 21% in water at 25 °C · Solubility in water, g/100ml at 25 °C: 21
Density: 2.350 g/cu cm · 2.35 g/cm³
Stability: All hypochlorite soln are unstable, esp if acidified, slowly decomp on contact with air /hypochlorite soln/ · Chlorinated lime is relatively unstable, even in solid form, and loses much of its activity over a period of a year. /Chlorinated lime/
Colour: white
Melting/freezing point: 100 ℃
Water solubility: 21 g/100㎖ (25℃)
Relative density: 2.35
n-Octanol/water partition coefficient (Kow): -2.46 (est.)
Decomposition temperature: (&amp, gt, 177 ℃)
Molecular weight: 142.98

Irritation and sensitisation studies

6 skin studies and 2 eye studies are on record.

Classed as highly irritating1

The study conclusions largely agree (100%). These tests are on the raw material itself; irritation at the amount in a finished product is a different question.
