A relative density value of 0.896 at 20°C was determined for the substance using a relevant test method. The result is considered to be reliable.
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
