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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Executive summary:
The density of the test substance was measured with a procedure similar to the OECD guideline, oscillating densitimeter method.
After calibration with air and water, the sample was measured at 20, 25, 30 and 40°C.
The density of exo-THDCPD (JP-10) was determined as 0.9356 g.cm-3 at 20°C and 0.9312 g.cm-3 at 25°C.

Description of key information
The density of THDCPD was determined as 0.9356 g.cm-3 at 20°C and 0.9314 g.cm-3 at 25°C.
The relative density (D20/4) was calculated as 0.9356.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.936
Additional information
Two reliable publications were identified, providing consistent values. However, in Xing 2009 the density was measured only at 25°C, while Wei 2010 provides values at four temperatures, including 20°C which is the prefered reference temperature for relative density (D20/4). Therefore it is considered as key data.
