Conclusions:
The density of the sample at 20 ºC was 0.9986 g/mL, the relative density (20/20 ºC) was 1.0004 g/mL and the relative density (20/4 ºC) was 0.9987 mg/L. The accurancy was ± 0.0005.
Executive summary:

The density of amides, C8-18 and C18 unsatd., N-(hydroxyethyl) was determined according to ISO 758 and pycnometer,Gay-Lussac type conforming to the dimension given in ISO 3507. The water bath temperature was at 19.9 ºC, the normal capacity was 25.073 cm3and the solvent used was hexene. The density of the sample at 20 ºC was 0.9986 g/mL, the relative density (20/20 ºC) was 1.0004 g/mL and the relative density (20/4 ºC) was 0.9987 mg/L. The accurancy was ± 0.0005.

Description of key information

The density was determined according to ISO Method 758 (Carrillo, 2008).

Key value for chemical safety assessment
