RESULTS

Determination 1

Density (d(20)): 0.9043 ± 0,0002 (g/ml)

Rel. density : D2020=0.9059 ± 0,0002

Determination 2:

Density (d(20)): 0,0.9043 ± 0,0002 (g/ml)

Rel. density : D2020=0,9059 ± 0,0002

Conclusions:
The test substance is less dense than water.
The mean relative density of the test item was D20/20 = 0,9059 ± 0,0002.
Executive summary:

The density of the test substance was measured according to OECD 109 / EU A3 guideline, using oscillating density meter. After calibration, two determinations were performed and the mean value was retained.

The relative density of the test item was measured as D20/20= 0.9059 ± 0.0002.

Description of key information

The test substance is less dense than water.

The mean relative density of the test item was D20/20 = 0,9059 ± 0,0002.

Key value for chemical safety assessment

Relative density at 20C:
0.906

Additional information

A fully reliable experimental study, conducted according to OECD 109 /EU A3 guideline, using oscillating density meter, is available. It is considered as a key study, and the result is retained as key data.
