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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- relative density
- Density:
- 1.262
- Temp.:
- 22 °C
- Conclusions:
- The relative density (compared to water at 4 °C) of the test item was found to be 1.262.
- Executive summary:
The relative density of the test item was determined according to Council Directive 92/69/EEC Part A. Method A.3 and OECD Test Guideline 109 using the air comparison pycnometer method. The relative density (compared to water at 4 °C) of the test item was found to be 1.262. This value is the mean of two experiments with three replicates each.
Reference
Before measurement the test item was liquefied, filled into the test vessel and cooled down in a refrigerator for crystallization. Subsequently the test item was stored at ambient temperature over night. Two test series with different weights were performed at ambient temperature (22.0 °C).
