Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
The relative density D 22/4 of the test article was determined to be 0.725.
Executive summary:

In a general physico-chemical properties study (13193), the test material was determined have a relative density of 0.725 at 22.0 °C by the pycnometer method based on Method A3 of Commission Directive 92/69/EEC.
