Conclusions:
The density was found to be 0.41 g/mL (410 g/L) at 22ºC.
Executive summary:

A study was conducted to determine the density of the test substance in accordance with CIPAC Method MT 169. A fixed amount was transferred to a measuring cylinder and shaken down by dropping 50 times using a dropping box. The volume of the sample was measured. The tap density was calculated by dividing the weight of the sample by its volume. The measurement was repeated twice at 22ºC. The density was found to be 0.41 g/mL (410 g/L) at 22ºC (Amin, 2009).

Description of key information

The density was determined according to CIPAC Method MT 169 (Amin, 2009).
