Applicant's summary and conclusion

Conclusions:
The density of the test substance was measured according OECD 109, by pycnometer method. The test substance is less dense than water.
The density of the test item was calculated as 774.3 ± 3.9 kg/m3 at 24.5±0.1°C, which is the mean of two values ± the standard deviation.
Standard deviation was 3.9 kg/m3, showing good correlation of the two determinations.
Executive summary:
