According to the weights, the density of the test item at 22°C was 1.478 g/mL in the test 1 and 1.490 g/mL in the test 2.

The mean value derived from test 1 and test 2 at 22°C was 1.484 g/mL.

 

Applicant's summary and conclusion

Conclusions:
Density was determined to be rho (22 °C) = 1.484 g/cm³
The study was performed according to OECD TG109 with accepltable restrictions and therefore reliability of Klimisch 2 has been assigned.
Executive summary:

The density of the test material sodium 3-[[(dimethylamino)thioxomethyl]thio]propanesulphonate was determined experimentally using the buoyancy method in a non-GLP test according to OECD guideline 109 as rho (22 °C) = 1.484 g/cm3.
