Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Executive summary:
Method
The density of test substance has been calculated using a pycnometer as described in the ASTM D 1817 -90.
Discussion
The precision of the method establishes that tests performed in duplicate on a same sample should differ no more than 0.02 g/ml at 25 °C from each other. The measured values of the density at 25 °C of the test substance, observed both for tests performed in duplicate on a same sample and for tests performed on samples of different lots, do not differ more than 0,006 g/ml from each other. The tests performed have therefore a precision abundantly lower than the limit imposed by the method and they can be considered valid.
Conclusion
The value of the density at 25 °C of the test item, obtained from the average of the values reported for each test, resulted of 1.124 g/ml.
Reference
From tests carried out in duplicate, Sample I returned an average value of density at 25 °C equal to 1.088 g/ml.
From tests carried out in duplicate, Sample II returned an average value of density at 25 °C equal to 1.092 g/ml.
From tests carried out in duplicate, Sample III returned an average value of density at 25 °C equal to 1.094 g/ml.
Description of key information
Density = 1.091 g/ml at 25 °C
Key value for chemical safety assessment
Additional information
The density of test substance was evaluated using a pycnometer as described in the ASTM D 1817 -90.
