Description of key information

The density of dodecan-1-ol is 0.9003 g/cm3 at 16°C.

Key value for chemical safety assessment

Relative density at 20C:
0.9

Additional information

The density of 0.9003 g/cm3 at at 16°C was determined in a reliable study in accordance with ASTM D-70. The result is considered to be reliable.

It is supported by a value of 0.83 at 24°C taken from a reliable handbook.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

The relative density values are similar across the category. Values are consistently within the range 0.80 - 0.90 at ambient temperature.
