Description of key information

The substance, stored in PE containers of different size was stable at temperatures between 15C°C and 25°C for a period of 5 years. During storage, no reaction between the packing and packed material occurred. Polyethylene vessels and PE bags with zip-fasteners did not show package defects  during the test. This is also valid for samples, which had been stored at 54°C for 14 days and at temperatures of 40°C, 1°C and -18°C for a period of 6 months.

Additional information

Slightly increased chlorine contents of maximum 2% and 4% were due to loss of crystal water, presumably, during 6 months and 5 years of storage, respectively.
