Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The relative density at ambient temperature (compared to water at 4 °C) was determined to be 1.37.
Executive summary:

A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item. The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 1.37 g/cm3 at 20 ± 0.5 °C and the relative density 1.37 with respect to water at 4 °C respectively.

Description of key information

The relative density at ambient temperature (compared to water at 4 °C) was determined to be 1.37 (4.4 -1).

Key value for chemical safety assessment

Relative density at 20C:
1.37

Additional information

A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item (reference 4.4 -1). The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 1.37 g/cm3 at 20 ± 0.5 °C and the relative density 1.37 with respect to water at 4 °C respectively.
