Executive summary:

Method

Relative density was determined by means of a pycnometer as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.

Result

Relative density: 1.564 at 19.5 °C.

Description of key information

Relative density: 1.564 at 19.5 °C

Key value for chemical safety assessment

Relative density at 20C:
1.564
