- 1.17
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1.17 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of the test substance is 1.17 g/cm3 (1170 kg/m3) at 20 °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 relative density was found to be 1.17 (1170 kg/m3) at 20 °C.

Description of key information
1.17 (corresponding to a density of 1170 kg/m3) at 20 °C, OECD TG 109, pycnometer method, Husband 1997.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.17
Additional information
Another study was performed to determine the density of the test substance in technical material in accordance with OECD TG 109 and in compliance with GLP. In this study, the relative density was determined to be 1.16.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
