- Executive summary:
The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 and in the OECD 109 was determined to be:
D420= 1.58

D420= 1.58
Key value for chemical safety assessment
- Relative density at 20C:
- 1.58
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.
