Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Relative density:

Experiment 1: 1.318

Experiment 2: 1.317

Mean: 1.32

Conclusions:
The relative density D20/4 was determined to be 1.32.
Executive summary:

The relative density D20/4 of the substance was determined using a gas comparison pycnometer in a GLP study according to EC A.3 and OECD 109. The relative density was determined in duplicate at 20°C obtaining a mean value of 1.32.

Description of key information

Relative density at 20°C: 1.32 (EC A.3, OECD 109: gas comparison pycnometer).

Key value for chemical safety assessment

Relative density at 20C:
1.32
