- Density:
- 1 610 kg/m³
- Temp.:
- 25 °C
- Conclusions:
- The density of the test substance is 1.61 g/cm3 (1610 kg/m3) at 25 °C.
- Executive summary:
To determine the density of the test substance, a study was performed using the pycnometer method according to OECD TG 109 in compliance with GLP. The density was found to be 1.61 g/cm3 (1610 kg/m3) at 25 °C
