Conclusions:
The density of test item was determined to be 1.1038 ± 0.0003 g/cm3 at 20 ± 0.4 °C.
This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows very good correlation of the two determinations.
Executive summary:

The study was performed in order to determine the density of test item according OECD 109, resp. EU A.3 guideline, using a pycnometer.

A density of 1.1038 ± 0.0003 g/cm3 at 20 ± 0.4 °C was measured. This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows very good correlation of the two determinations.

Description of key information

The density of test item was determined to be 1.1038 ± 0.0003 g/cm3 at 20 ± 0.4 °C.

Key value for chemical safety assessment

Relative density at 20C:
1.104

Additional information

A fully reliable experimental study, conducted according to OECD 109/ EU A3 guideline is available.

It is considered as a key study, and the result is retained as key data.
