Description of key information

The relative density of the substance at 20 ± 0.5°C is 0.7627

Key value for chemical safety assessment

Additional information

Hydrocarbons, C11-C16, n-alkanes, isoalkanes, <2% aromatics has a measured density value of 0.7663 g/cm3 at 15°C and 0.7627 g/cm3 at 20°C using an oscillating densitometer. Full study details are not available therefore reliability could not be assigned to these data.

Reliable data are, however, available for related substances in the relevant carbon number range, including other Fischer-Tropsch process-derived substances.

In OECD 109 studies using the pycnometer method, which were conducted in compliance with GLP, Hydrocarbons, C10-C13, n-alkanes, isoalkanes, <2% aromatics (GS190), Hydrocarbons, C12-C15, n-alkanes, isoalkanes, <2% aromatics (GS215) and Hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics (GS250) had measured relative density values of 0.75 at 20.2 ± 0.5°C (density = 750 kg/m3 at 20.2 ± 0.5°C), 0.763 at 20 ± 0.5°C (density = 763 kg/m3 at 20 ± 0.5°C) and 0.773 at 20 ± 0.5°C (density = 773 kg/m3 at 20 ± 0.5°C) respectively. The results are considered to be reliable and are used as weight of evidence.
