Conclusions:

The substance is more dense than water.

Executive summary:

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

Experiment was performed at 20 °C in duplicate; the mean density was calculated, and converted to relative density d20/4.

The relative density (d20/4) of the test substance was calculated to be 1.1031.

Description of key information

The substance is more dense than water.

Key value for chemical safety assessment

Relative density at 20C:

1.103
