Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
