Results and discussion
Density
- Key result
- Type:
- relative density
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- We tried to measure the relative density using heptane or liquid paraffin as an immersion liquid, but the air bubbles in the test item could not be completely removed and the test item swelled in solvents.
Any other information on results incl. tables
The measurement of the relative density should be performed with a solvent that does not dissolve the test item. As the result of preliminary test, heptane and liquid paraffin were confirmed to be poor solvents for the test item. We tried to measure the relative density using heptane or liquid paraffin as an immersion liquid, but the air bubbles in the test item could not be completely removed and the test item swelled in solvents. Therefore, it is concluded that the relative density of test item could not be measured.
Applicant's summary and conclusion
- Conclusions:
- It is concluded that the relative density of the registered substance could not be measured under this test condition.
- Executive summary:
-Test guideline
OECD Guidelines for Testing of Chemicals, No. 109, October 2, 2012, "Density of Liquids and Solids: Pycnometer (liquids and solids)"

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).
