Additional information
For the evaluation of this endpoint data from an experimental study were used as key information. The study was conducted according to GLP and according to OECD guideline 109. The test data are considered as reliable without restrictions.
The density of the solid was measured with a gas comparison pycnometer. Two measurements were conducted with 18.16 g and 20.03 g, respectively. Results indicate that potassium thiosulfate has a relative density of 2.37 at 22.6 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
