Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A recent and well documented study was selected from the large body of available information (see literature search), Meng (2008). The reported density at 0 °C was in good agreement with that reported by Gillo (1936) at the same temperature, and with Merck (2001) at 20 °C.

The study by Meng is considered to be of suitable accuracy for the purposes of classification and labelling and risk assessment, with no nearby regulatory cut-offs. The study was very well documented and addressed all relevant experimental parameters. The study addressed the errors in detail and compared the results with other workers. As a result, testing does not appear scientifically necessary based on the use of existing data and, given the above points, the criteria in Regulation (EC) No. 1907/2006, Annex XI, 1.1.1 are considered to be met.
