Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Type:
- relative density
- Density:
- 1.202
- Temp.:
- 20 °C
- Remarks on result:
- other: mean value of 2 determinations
- Conclusions:
- The relative density at 20 ºC was was 1.202.
- Executive summary:
According to the OECD Guideline 109 (Density of Liquids and Solids) corresponding to A.3., Council Regulations EC No 440/2008 the solid sample was accurately weighed into a 20 mL pycnometer and by displacement of the solvent (n-heptan), its equivalent volume was determined. Finally, the density of the sample was calculated. The relative density at 20 ºC was 1.202.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
