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

The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method.

Calibration was performed with water. Experiment was performed at 20 °C in duplicate, and the mean density was calculated, and converted to relative density vs water at 4°C.

 

The density of the test substance at 20 ºC was 0.867 g/cm3. The relative density D20/4 was 0.867.

Description of key information

The substance is much less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.867

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study, and the result is retained as key data.
