- Conclusions:
- The density of the test substance at 20ºC was 0.9819 g/mL, the relative density (20/20ºC) was 0.9848 and the relative density (20/4ºC) was 0.9820. The accuracy was ± 0.0005.
- Executive summary:
A study was conducted to determine the density of amides, C8-18 and C18-unsatd., N,N-bis(hydroxyethyl) according to ISO 758 using a pycnometer, Gay-Lussac type, conforming to the dimension given in ISO 3507. The water bath temperature was at 19.9ºC, the normal capacity was 25.073 cm3 and the solvent was hexene. The density of sample at 20ºC was 0.9819 g/mL, the relative density (20/20ºC) was 0.9848 g/mL and the relative density (20/4ºC) was 0.9820 mg/L. The accuracy was ± 0.0005.

Description of key information
The density was evaluated using a pycnometer, Gay-Lussac type, conforming to the dimensions given in ISO Method 3507 (Carrillo, 2009).
Key value for chemical safety assessment
- Relative density at 20C:
- 0.985
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.
