Applicant's summary and conclusion

Conclusions:
A pycnometer was used for the determination of the density and relative density of Dermol TDSA.
The density of the test item at 20ºC was 0.969 g/cm3 (0.969  103 kg/m3).
The relative density was 0.969.

The relative density of the test substance was found to be 0.969 g/cm³ at 20 °C.
Executive summary:

In this guideline 9OECD 109) study, [conducted with GLP certification], the relative density of the test substance (EC 243-214-1) was found to be 0.969 g/cm³ at 20 °C.
