Conclusions:
The pour density of the test substance was 0.65 g/mL (650 g/L) and the tap density was 0.82 g/mL (820 g/L).
Executive summary:

The density of the test substance was determined by methodology appropriate for its physical state according to CIPAC MT-159, OECD TG 109, OPPTS 830.7300 and ASTM E727-91. An appropriate amount of the test substance was weighed in order to fill 90% of a 50 mL glass cylinder. The test substance was poured into the cylinder, leveled off and the initial volume measured to the nearest 1 mL. The bottom of the cylinder was then raised 25 mm and allowed to drop until a total of 100 taps were made and a second volume measured and recorded. The pour density of the test substance is its weight divided by the initial volume, expressed in g/mL. The tap density of the test substance is obtained by dividing the weight of the test substance by the second volume (g/mL). The pour density of the substance was 0.65 g/mL (650 g/L) and the tap density was 0.82 g/mL (820 g/L).
