- Conclusions:
- The density of the test substance was calculated as 1.1483 ± 0.0004 g/cm3 at 20.0 ± 0.2 °C and the relative density is determined as D20/4 = 1.1483
Denser than water - Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, using the pycnometer method with replacement liquid.
Two determinations were performed and the mean value was retained.
This result was then converted to relative density.
Mean density: 1.1483 g/cm3at 20.0 ± 0.2 °C
Mean relative density (D20/4) : 1.1483

The density of the test item was calculated as 1.1483 ± 0.0004 g/cm3 at 20.0 ± 0.2 °C, which is the mean of two independent determinations ± the standard deviation. Standard deviation shows good correlation of the two determinations. Therefore, the study is considered valid.
Description of key information
The density of the test item was measured as 1.1483 ± 0.0004 g/cm3 at 20.0 ± 0.2 °C and the relative density is determiend as D20/4 = 1.1483
Key value for chemical safety assessment
- Relative density at 20C:
- 1.148
Additional information
A fully reliable experimental study, conducted under GLP according to OECD 109 /EU A3 guideline, using pycnometer method with replacement liquid, is available. It is considered as a key study, and the result is retained as key data.
