Applicant's summary and conclusion
- Conclusions:
- The relative density D20/4 of the substance was determined to be 1.244.
- Executive summary:
The relative density of the solid substance was determined at 19.5°C using a gas comparison pycnometer in a GLP study according to EC A.3 and OECD 109. The relative density D20/4 was determined to be 1.244.
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.
