- Key result
- Type:
- relative density
- Density:
- 1.23 other: dimensionless
- Temp.:
- 22 °C
- Type:
- density
- Density:
- 1 230 kg/m³
- Temp.:
- 22 °C
- Conclusions:
- The density of the test substance is 1.23E+03 kg/m3 at 22 °C.
- Executive summary:
- To determine the density of the test substance, a GLP-compliant study was performed using the pycnometer method according to OECD TG 109. The density was found to be 1.23E+03 kg/m3, corresponding to a relative density of 1.23, at 22 °C.
