Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The density of the test item at 20 °C is: ρ = 0.9444 g/cm3
Estimated accuracy: ± 0.0001 g/cm3
Description of key information
The density of the substance at 20 °C is 0.9444 g/cm3.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.944
Additional information
Two GLP studies were conducted.
BASF GLP study no. 14L00334 determined the relative density in accordance with the OECD Guideline for the Testing of Chemicals 109. using the oscillating densitimeter to be 0.9444 at 20 °C.
In a non-GLP supporting study (BASF, PH 2615, 1980) the density was determined. Only limited documentation of the study and the test item purity was available. The density of the test item was determined at 10 °C, 20 °C and 40 °C to be 0.9521 g/mL, 0.9399 g/mL and 0.9277 g/mL respectively.
The value from the BASF GLP study was chosen as key value for the relative density.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
