Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

Two tests with different amounts of the test item were performed to determine the relative density D420 at a temperature

of 20 °C ±0.01 °C.

Test No. Temperature [°C] Amount of test item [g] Average sample volume [cm³] Density [g/cm³]*

1 20 8.88 7.19419 1.23433

2 20 8.76 7.02453 1.24706

* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.

The mean density of the test item at 20 °C is 1.24073 g/cm³. The relative density D420 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³). The relative density is D420 = 1.241.

Applicant's summary and conclusion

Conclusions:
According to OECD Test Guidelines 109 (2012), Regulation EC No. 440/2008 Method A.3. and EPA OCSPP Test Guideline 830.7300 (2002),
the relative density D420 of the test item at 20 °C ±0.01 °C (compared to water at 4 °C) is D420 = 1.241.
