Conclusions:

The density of test chemical was determined following OECD Guideline 109 (Density of Liquids and Solids) and according to the method recommended in the International Pharmacopoeia, fourth Edition, 2014 . The mean pour density and tapped density of the test chemical was determined to be 0.2520 g/cm³ and 0.3480 g/cm³ at 29.5°C and 978.2 hPa, respectively.

Executive summary:

The density of test substance was concluded following OECD Guideline 109 and according to the "Test methods: Pour density and tapped density of powders” recommended in The International Pharmacopoeia, Fourth Edition, 2014 using bulk density apparatus. The mean pour density and tapped density of test substance was determined to be 0.2520 g/cm³ and 0.3480 g/cm³ at 29.5°C and 978.2 hPa, respectively.
