Applicant's summary and conclusion

Conclusions:

The density of substance was found to be 1.0468 g/mL at 20.1°C.

Executive summary:

The density of the substance has been determined employing Pykcnometer method according to the OECD 109 guideline 'Density of Liquids and Solids'. The capacity of the pyknometer and the specific gravity of wetting solution was determined by recording the weights of empty pyknometer, pyknometer with water and pyknometer with wetting solution. The density of substance was calculated from the capacity of the pyknometer and specific gravity of wetting solution. The test was performed at 20.1 °C, in duplicate and the mean density of substance was found to be 1.0468 g/mL (or 1.0468 g/cm3).
