- Type of method:
- pycnometer method
- Type:
- density
- Density:
- 0.996 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of the test substance was calculated as 0.9956 ± 0.0010 g/cm3 at 20.0 ± 0.4 °C.
The substance is slightly less dense than water. - Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method. The determination was performed in duplicate and the mean value was retained.
The density of the test substance was measured as 0.9956 ± 0.0010 g/cm3 at 20.0 ± 0.4 °C.

The density of the test item was calculated as 0.9956 ± 0.0010 g/cm3 at 20 ± 0.4 °C. This value is the mean of two independent determinations ± the standard deviation. Correspondence of the values is very good. Therefore, the study is considered valid.
Description of key information
The density of the test substance was measured as 0.9956 ± 0.0010 g/cm3 at 20.0 ± 0.4 °C.
The substance is less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.996
Additional information
A fully reliable experimental study, conducted according to a recognized OECD109 / EU A3 guideline, pycnometer method and under GLP, is available. It is considered as a key study and the value can be used for the purpose of CSA.
The density of the test substance was calculated as 0.9956 ± 0.0010 g/cm3 at 20.0 ± 0.4 °C.
