Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The relative density of the substance at 20°C was 0.7885

Key value for chemical safety assessment

Relative density at 20C:

Additional information

Hydrocarbons, C16-C22, n-alkanes, isoalkanes, , <2% aromatics has a measured density value of 0.7919 g/cm3 at 15°C and 0.7885 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, C15-C19, n-alkanes, isoalkanes, <2% aromatics (GS270) and Hydrocarbons, C18-C24, isoalkanes, <2% aromatics (GS310) had measured relative density values of 0.783 at 20.2 ± 0.5°C (density = 783 kg/m3 at 20.2 ± 0.5°C) and 0.797 at 20 ± 0.5°C (density = 797 kg/m3at 20 ± 0.5°C) respectively. The results are considered to be reliable and are used as weight of evidence.
