Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There is no data available for Hydrocarbons, C16-C18, Isoalkanes, <2% aromatics. Data is therefore read across to Hydrocarbons, C13-C18, n-alkanes, isoalkanes, cyclics, < 2% aromatics; Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, <2% aromatics; and Hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, <2% aromatics, using the analogue approach. 

The estimated auto ignition temperature of the substance Hydrocarbons, C13-C18, n-alkanes, isoalkanes, cyclics, <2% aromatics is greater than 200°C at 1 atm.

The auto ignition temperature of the substance Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, <2% aromatics, measured according to ASTM E 659 is greater than 221°C at 1 atm.

The extrapolated auto ignition temperature for the substance Hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, <2% aromatics is minimum 200°C.
