Evaluation of available information for relative density (ref. enpoint specific guidance R.7.1.4.3 p 61):

The relative density related to seawater allows a judgement on whether a substance will float or sink

based on the standard phrases of the European Classification System criteria of the Bonn

Agreement (1983). Assuming that the water solubility is relatively low (<50g/l) the substance is likely to float with a density <1.0 and sink if the density is > 1.03. Tetramethylenediamine has a relative density of 0.877 g/cm3.

Applicant's summary and conclusion

Conclusions:
Evaluation of available information for relative density (ref. enpoint specific guidance R.7.1.4.3 p 61):
The relative density related to seawater allows a judgement on whether a substance will float or sink
based on the standard phrases of the European Classification System criteria of the Bonn
Agreement (1983). Assuming that the water solubility is relatively low (<50g/l) the substance is likely to float with a density <1.0 and sink if the density is > 1.03. Tetramethylenediamine has a relative density of 0.877 g/cm3 but the substance is very soluble in water and therefore not will float on water.
Executive summary:

The relative density related to seawater allows a judgement on whether a substance will float or sink based on the standard phrases of the European Classification System criteria of the Bonn Agreement (1983). Assuming that the water solubility is relatively low (50g/l) the substance is likely to float with a density 1.0 and sink if the density is > 1.03. Tetramethylenediamine has a relative density of 0.877 g/cm3 but the substance is very soluble in water and therefore not will float on water.
