*The relative density D20/4 is the ratio between the measured density of the test substance at 20°C and the density of water at 4°C (= 0.99997 g/cm3). The relative density has no dimension.
Description of key information
Relative density: 0.934 at 20°C (OECD 109)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.934
Additional information
A relative density value of 0.934 at 20°C was determined for the substance using an oscillating densitometer in accordance with OECD Test Guideline 109 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.
The key study is supported by a relative density value of 0.93 at 20°C which was reported for the substance in a handbook or collection of reliable data which has been subject to peer review and in which the original references are traceable. In addition, a predicted density value of 0.96 g/cm3 at 20°C was obtained for the substance using a validated QSAR estimation method.
In available secondary sources to which reliability could not be assigned, density values of 0.93 - 0.94 g/cm3 at 20 - 25°C were reported for the submission substance.
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).
