Test item temperature: 20.0 ± 0.5 °C

Conclusions:
The substance is less dense than water.
Executive summary:

The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method. Two runs were performed, and the mean density at 20.0 °C was calculated. This result was then converted to relative density towards water at 4 °C.

Mean density: 925.2 kg/m3

Mean relative density: 0.925

Test item temperature: 20.0 ± 0.5 °C

 

The density of the test item has been determined to be 925.2 kg/m3 at 20.0 ± 0.5 °C and a relative density (D20/4) of 0.925.

Description of key information
