Applicant's summary and conclusion

Conclusions:
The density of the substance was determined to be 0.940 g/cm3.
Executive summary:

The density of the substance was determined at 20.4°C using a pycnometer in a non-GLP study according to OECD 109. The density was determined in duplicate obtaining a mean value of 0.940 g/cm3.
