Conclusions:
The substance is as dense as water.
Executive summary:

The density of the test substance was measured under GLP according EU A3/OECD 109 guideline, pycnometer method.

Two runs were performed, and the mean density towards water at 20.0°C was calculated taking into account the correction for air pressure. This results was then converted to relative density towards water at 4°C.

The density of the test substance at 20.0°C is 1.0031 g/cm3, and its relative density (D20°C/4°C) is 1.003.

Description of key information

Density at 20°C is 1.0031 g/cm3

Relative density (D 20/4) = 1.003

The substance is as dense as water.

Key value for chemical safety assessment

Relative density at 20C:
1.003

Additional information

A fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Therefore, it is considered as a key study. The result is retained as key data for purpose of CSA.
